Tuohu Lake area is low-lying, which is obviously influenced by the high water level jacking of Huaihong New River in flood season, and its self-discharge capacity is insufficient. In addition, its own storage capacity is not large, and its storage capacity is weak, so it is easy to cause waterlogging and flooding. The contradiction between flood control, water storage irrigation, ecological restoration and environmental improvement is becoming increasingly acute, and the requirements for regional flood control and drainage are further improved. The flood control dispatching of Tuohu Lake and its surrounding tributaries tends to be complicated, and the ability of monitoring and dispatching emergency needs to be improved.
(one) The current shoreline resources need to be integrated.
Congtuo LakeAccording to the present situation of shoreline utilization, there are water conservancy projects, bridges and lines on both sides of Tuohu Lake.64Place, occupy the coastline length.16789rice.With the rapid economic development along the river and the increase of town scale, the development and utilization of shoreline resources are on the increase, and the coastline layout of some river sections is notReasonable, the shoreline resources are seriously wasted.
(2)Shoreline management mechanism still needs to be improved
TuohuShoreline not only has the natural functions of flood storage, protecting aquatic habitats and maintaining the health of lakes, but also is the carrier of land resources for river-related projects such as water intake and drainage outlets and tourist facilities. The diversity of its functions also determines the complexity of its management. As far as the effect of shoreline management, protection, development and utilization is concerned, it is easy to appear in the process of shoreline use because it involves many industries and departments.Problems such as "multiple policies" and "separate policies" are not conducive to effective protection and rational utilization along the lakeshore, and need to be further straightened out and improved urgently.TuohuShoreline management system and mechanism, and refine the provisions on shoreline management and protection.
(three)The phenomenon of sporadic illegal occupation of shoreline rivers still exists.
The phenomenon of illegal occupation of the shore and purse seine farming is sporadic, and the river-related construction projects in some areas need to be further standardized. The phenomenon of illegal farming, illegal construction, livestock and poultry farming and other encroachment on the river is still prominent.

According to Water Function Zoning of Anhui Province,Tuohu five rivers territory.sevenSquare kilometers is the transition zone, but the water function zone is not defined in the upper reaches of Tanghe River. Once there is pollution in the upper reaches, it will cause great losses in the fishery and agricultural water use zone of Tuohu Lake water function zone. The monitoring ability of water resources is weak, and monitoring facilities have not been installed in non-agricultural water intakes, so the classification supervision of water functions needs to be further strengthened.
In addition,The water resources and deployment capacity of Tuohu Lake are obviously insufficient.TuohuPer capita water resources in river basinlow, is a typical water shortage area, the local available water resources are inherently insufficient; Second, under the stress of water shortage,Affected by the upstream,Urban life and industrial production occupy the ecological water of rivers and worsen the water ecological environment; Third, the lack of water resources allocation capacity has aggravated the deterioration of water quality in rivers and lakes.
Pollution sources entering the lake mainly come from the upper reaches of Tuohe River and Beituo River. The pollution in the lake area is mainly agricultural non-point source pollution. A large number of studies have proved that in the process of rainfall, the initial rainwater is mixed with a lot of dust and sediment, which has a high pollutant load and poor water quality. Agricultural pollution residues can enter the lake area through surface runoff, which has a great impact on the water quality and pollutes the lake water environment.
Agricultural non-point source pollution has not been effectively controlled: the land along Tuohu Lake is mainly planted with rice and wheat, and more fertilizers and pesticides are used. The residues are discharged into Tuohu Lake with agricultural water, and the residues contain fertilizer deposits and undegraded pesticide components. The lakeaccumulateThe residual bait will go deep into the water body and cause pollution; Tuohu coastNearby individualsPoultry farming mainly raises ducks and geese, and the feed put in the process of raising ducks and geese and the feces of ducks and geese flow into the water body to cause pollution.
The treatment capacity of township domestic pollution needs to be improved: the township domestic garbage in the basin is piled up in disorder, the progress of classification and reduction is slow, the resource recycling is insufficient, and the level of harmless treatment technology is not high; Due to the lack of sewage collection and treatment facilities, part of the domestic sewage from the villages around the lake area is directly discharged into the lake from the ditches entering the lake.
The main water environment problems in Tuohu Lake area are: the quality of drinking water source is not up to standard, the eutrophication of Tuohu Lake exists, and the safety risks of water source exist, as follows:
(one) The environmental quality of drinking water source water is not up to standard.
At present, there are two centralized drinking water sources at township level in Tuohu Lake area. According to the monitoring data, the two drinking water sources have not reached surface water.ⅢClass A, the total phosphorus and total nitrogen in the lake exceeded the standard, and the rate of exceeding the standard reached.100%; Affected by the water quality of Tuohu Lake, the total phosphorus and total nitrogen in the water intakes of Shenji Town and Shuangzhongmiao Town in Wuhe County have exceeded the standard in recent years.
(2) There is eutrophication in Tuo Lake.
The total nitrogen and total phosphorus in Tuohu Lake area are inferior to those in Tuohu Lake area.ⅤThe water quality standard is similar, and the level of nutrient-rich salt is generally high. In recent years, Tuohu Lake has changed from mild eutrophication to moderate eutrophication.2015year-2016Niantuo Lake is slightly eutrophic;2017year-2018In, it was moderately eutrophic;2020The annual eutrophication index is58.67It is moderately eutrophic.
(three) There are security risks in water sources.
Due to the heavy rain in summer, the sewage mass in the upper reaches of Tuohu Lake transits, causing pollution in Tuohu Lake and its surrounding areas, and a large number of crabs, shrimps and fish die in Tuohu Lake. According to statistics,2016Water surface area of disaster-stricken aquaculture in Tuohu Lake, Wuhe County in44398Mu,2018The water quality deteriorated again in Niantuo Lake.
Insufficient ecological water demand guarantee: the social and economic development in Tuohu Basin is rapid, and the water consumption is large. In dry years and dry seasons, the water shortage in the basin is serious, which squeezes the ecological environment water in the river. At the same time, most control sections of Tuohu Lake and main tributaries lack ecological flow scheduling schemes.
Over-exploitation of river and lake wetlands has threatened biodiversity: different forms of exploitation and utilization have led to obvious shrinkage of wetlands, and environmental pollution has endangered wetland animals and plants and threatened wetland ecosystems. The controlling buildings in Tuohu Lake and its main tributaries play an important role in flood control and irrigation, but they also isolate the communication between rivers and lakes, block the migration of aquatic animals, and destroy the habitat and breeding habitat of fish, shrimp and crabs, as well as the habitat of rare waterfowl. Excessive fishing and hunting have reduced the food sources of fish-eating birds, and the phenomenon of indiscriminate fishing in Tuohu Lake has occurred from time to time, which has seriously threatened biodiversity.
Biodiversity protection is under pressure: in flood season, lakes and depressions can hold back floods to ensure the safety of flood control in important cities. However, there are many kinds of aquatic organisms in lakes and a considerable number of waterfowl are distributed in lakes and wetlands, so the function of biodiversity maintenance is also very important. becausehistoricalOver-breeding, wetland vegetation is damaged to some extent, waterfront vegetation is lacking, beaches are exposed, bird breeding and habitat are not guaranteed, and biodiversity protection is under pressure. The key point of protection is to strengthen the protection and restoration of lake depressions and control the development intensity.
Imperfect law enforcement and supervision system: the management and protection system of Tuohu Lake is not perfect, and some water activities have no rules to follow and no laws to follow. The system of supervision of lake-related construction projects, compensation for occupied waters, daily inspections and other systems need to be further improved.
The law enforcement and supervision mechanism is not perfect: the law enforcement and supervision mechanisms such as illegal water activities disposal and joint law enforcement are not perfect, and the law enforcement and supervision means are not complete. The spatial management and control of the waters around the lake and the shoreline management and protection involve many departments, which have overlapping functions and insufficient coordination and linkage, and the joint supervision needs to be further strengthened.
The informatization construction of law enforcement supervision lags behind: the information sharing of administrative law enforcement supervision related to lakes is not enough, the communication of cross-regional and cross-industry law enforcement supervision information is not smooth, the construction of comprehensive information management system lags behind, and the accuracy, comprehensiveness and timeliness of law enforcement supervision information need to be improved urgently.

2) General requirements
Tuo Lake is an important water area with multiple functions and comprehensive benefits, and it is also an important natural resource and strategic economic resource. For a long time, Tuo Lake has played a very important role in the social and economic development of Wuhe County and even Bengbu City. according to“Give priority to protection and coordinate development"and“Development in protection and protection in development"The principle of Tuo Lake protection, the overall requirements are as follows:
oneProtect the lake form, prevent encroachment and reclamation of the lake area, and reduce the lake area.
2Strengthen pollution prevention and control to improve the water quality of lakes; Control and reduce the input of exogenous substances, control the breeding capacity and implement ecological fisheries; Strengthen ecological protection and maintain the healthy life of lakes.

fiveIncrease the publicity of lake protection, raise the awareness of lake protection of the whole people, encourage public participation, and make the protection of Tuo Lake become the consensus of the surrounding people.
The sequence of functional orientation of Tuohu Lake in Wuhe County is flood storage and waterlogging detention, irrigation, water supply, ecology and aquatic products provision.
fiveProtection and control measures
There are Wuqiao Town, Shenji Town, Xiaowei Town, Tuohu Township and Shuangzhongmiao Town around Tuohu Lake in Wuhe County.fiveA township. According to the flood control standard (GB50201-2014) The protection level of flood control protection object of Tuohe dike isⅣAnd so on, the flood control standard istwentyOnce in a year, the drainage standard is reached.10Once in a year
There is a flood control sluice at the entrance of Tuohu Lake into Huaihong New River, and the flood diversion of Huaihong New River will not affect the flood control safety in the lake area. The main threat of Tuohu Lake is that the waterlogged water in the lake area is produced when it encounters the flood diversion of Huaihong New River.“Guanmenyan"The situation.
It is planned to build a new Siheli drainage pumping station in Haan Lee of Sihe River to solve the problem of waterlogging near Siheli when the high water level of Tuohu Lake is jacking. It is planned to reinforce the existing dike from Siheli Bridge to Dalu main canal, so as to solve the problem that the section of dike body in this section can not fully meet the requirements of flood control safety.
According to the defined shoreline functional zoning, the management requirements for the protection and utilization of Tuohu shoreline in Wuhe county are put forward, so as to further standardize the shoreline development and utilization behavior, and reasonably determine the inter-departmental management scope and responsibilities related to the shoreline utilization behavior. arrive2025In 2000, the management requirements were strictly implemented, the intensive and efficient utilization of shoreline resources was realized, and the comprehensive utilization level of shoreline resources was improved.
According to "Protection and Utilization Planning of Tuohe and Tuohu ShorelinesThe results of functional zoning of shoreline, the protection objectives and management requirements of functional zoning are managed.

For projects that have been built in the shoreline functional area and have a significant impact on flood control, water supply, bank slope stability and water ecological environment, we should adhere to the principle of seeking truth from facts, and put forward opinions on repaying them in a planned and step-by-step manner according to the principles of justice, fairness and openness.
(threeManagement should be strengthened and strictly controlled for shoreline utilization projects prohibited from development in the shoreline functional area, and no unit or individual is allowed to develop and utilize the shoreline without authorization. For the established or planned shoreline utilization projects, we should communicate with relevant departments in time and put forward adjustment opinions.
(four) For the projects controlled for development and utilization in the shoreline functional area, the principles, measures and restrictive conditions for control and utilization should be put forward according to the attribute requirements of the functional area. Such as controlling the project scale, quantity, shoreline utilization length, etc.
(five) For the projects that conform to the development and utilization of the shoreline functional areas, the basic requirements and management measures for the development and utilization of the projects should be put forward according to the specific conditions of the development and utilization projects, combined with the attributes and evaluation opinions of the shoreline functional areas.
We will fully implement the strictest water resources management system, build a water supply system with reasonable layout, optimized allocation, reliable capacity and safe guarantee, rationally arrange water for life, production and ecology, and improve the guarantee capacity of urban and rural water supply, agricultural irrigation and ecological water storage through rational allocation of water resources.

6.2Coordination of planning
This plan is based on“Strengthen lake protection, give full play to lake functions, rationally utilize lake resources, maintain lake ecological environment, prevent and control water disasters, standardize lake development and utilization behavior, and realize sustainable utilization of lake resources."And compiled, with significant protective characteristics. The planning content fully considers the connection of flood control and drainage, water resources, water ecology, aquaculture, agriculture, forestry, water environment and other aspects. After the implementation of the planning, it will improve the flood control and disaster reduction capacity of Tuohu Lake, improve the water quality environment of Tuohu Lake, repair the severely damaged Tuohu Lake ecology and promote the sustainable development of regional economy and society. The planning conforms to the sustainable development strategy and policies established by the state.
The planning conforms to the requirements of laws and regulations such as People’s Republic of China (PRC) Water Law, People’s Republic of China (PRC) Flood Control Law, People’s Republic of China (PRC) Water and Soil Conservation Law, People’s Republic of China (PRC) Water Pollution Prevention Law, People’s Republic of China (PRC) Aquatic Wildlife Protection Implementation Regulations, Wetland Protection Management Regulations and Anhui Wetland Protection Regulations.
According to the identification and analysis of environmental impact, the implementation of this plan has good environmental benefits, and its main beneficial effects mainly include:
oneAccording to the once-in-20-year-period design flood control standard, strengthening and upgrading dikes and building flood control channels at the top of dikes will play a positive role in improving people’s production and living environment and providing flood control security for the economy and society.
2By preventing and controlling the pollution of rivers entering the lake, promoting the prevention and control of agricultural non-point source pollution, livestock and poultry breeding pollution, speeding up the centralized treatment of rural domestic sewage and promoting the construction of township domestic garbage treatment facilities, etc., the prevention and control measures of aquaculture pollution, such as returning fish (fields) to the lake and promoting healthy ecological farming, can reduce endogenous pollution, improve the water quality of the lake and increase the available water resources, which has a positive role in promoting economic development.
threeThe implementation of protection measures such as aquatic vegetation restoration and fish resources protection (proliferation and release, control of fishing intensity and reform of fishery management mechanism) is beneficial to the restoration and protection of fishery resources and aquatic organisms in Tuohu Lake, and to the restoration and protection of biodiversity in Tuohu Lake, so as to make rational use of Tuohu Lake resources on the basis of full protection, realize significant and sustained growth of biological output and economic output in Tuohu Lake, and at the same time maintain and improve the natural ecological environment of the region and river basin.
fourThrough the delineation of Tuohu shoreline development and utilization functional zones (shoreline protection zones) according to lawfiveA reserved areaeightA restricted development zonesevenA development and utilization areafourA total of24), strictly control the space of lake waters (control the construction of lake-related projects, scientific demonstration, restoration and remediation, and special cleaning and rectification), promote the demarcation of management scope (delimit the management scope of rivers and lakes and the management and protection scope of water conservancy projects), strengthen shoreline protection and economical and intensive utilization (strengthen the control of shoreline use and economical and intensive utilization, strictly control the intensity of development and utilization) and supervise the disposal of solid waste (strengthen the supervision of solid waste stacking, transfer and dumping, and improve the treatment of solid waste)
fiveThe implementation of the plan can protect important infrastructure such as water conservancy projects, which is conducive to lake flood control and water supply safety and has a positive effect on promoting economic and social development.
sixThrough the health assessment of Tuo Lake in different periods (before, during and after the implementation of the plan), the health status of Tuo Lake, the implementation effect of the protection plan and the existing problems were evaluated, so as to provide more targeted suggestions and measures for the protection of Tuo Lake.
sevenIt plays an important role in improving the eutrophication of Tuohu Lake by strengthening the water ecological protection in key areas such as the headwaters, water conservation areas and ecologically sensitive areas of the main tributaries of Tuohu Lake, and carrying out forest greening and efficiency improvement projects, degraded forest restoration projects, young and middle-aged forest tending projects and immature forest conservation projects in the water conservation areas of the river basin to ensure the water quality at the headwaters. By reducing the pollution load of rivers entering the lake, strengthening the control of endogenous pollution, proliferating filter-feeding fish and strengthening the protection and restoration of the lakeshore zone, the water pollution degree of Tuo Lake is reduced and its nutritional status index is reduced.
Generally speaking, all the measures to be taken in this plan can promote the harmonious coexistence between man and nature to a certain extent, and at the same time promote the sustainable and coordinated development of regional economy and society and the resources and environment of Tuohu Lake.
one, planning the impact of engineering construction.
Measures such as lake shoreline regulation and dredging basically do not produce new pollution sources, but in the construction process, mechanical operation may affect the water quality in a short period of time and destroy aquatic organisms in the lake. Improper sludge disposal will cause certain pollution to farmland and water areas in the surrounding areas. Produced during the construction period of the project“three wastes in industrial production"And noise will have a certain impact on the lives of construction workers and nearby residents. Earthworks are prone to local soil erosion, and some projects will also have some impacts on transportation, water supply, flood control and drainage during construction, but these impacts are short-term and have a small impact range, which can be reduced or eliminated through reasonable construction arrangements and environmental protection measures.
2The influence of returning farmland (polder) to lakes
The plan will implement the scheme and plan of returning farmland to lake and returning polder to lake. Withdrawing farmland and polder will damage the economic interests of farmers and fishermen, especially may change their way of life and affect the lives of residents around the lake. Government departments should actively strengthen environmental protection propaganda, pay attention to the production and life of the affected residents and formulate compensation plans when implementing the plan.
three, the impact of the adjustment of fishery culture
The total withdrawal of polder and the reduction of purse seine farming will reduce the number of its employees, affect its normal production and life, and have a certain adverse impact on economic development in the short term. However, the adjustment of aquaculture structure and mode plays an important role in the restoration of aquatic vegetation and the diversity of fish population structure in Tuohu Lake. It is beneficial to improve the health of Tuohu Lake and promote the sustainable development of economy.
four, the impact of tourism development
Tourism development has a positive effect on residents’ leisure, entertainment, culture and education, and can improve residents’ happiness. However, tourism development may cause the lake area to shrink and the wetland to be destroyed, and the sewage and waste generated by various water sports, restaurants and entertainment in tourist attractions may have an impact on the environment of Tuohu Lake.
one) social environmental protection countermeasures
Reasonably plan the construction site and resettlement methods, control the scale of the project, and try not to occupy or occupy less cultivated land. For the cultivated land occupied by the project that cannot be avoided, the cultivated layer soil is collected for soil improvement of reclaimed cultivated land, inferior land or other cultivated land. After the completion of the project, the cultivated land temporarily occupied by the construction will be reclaimed in time. Develop circular, ecological and intensive agriculture, and optimize the structure and layout of land use. During the project construction, the production wastewater and domestic sewage should be treated, and appropriate dust suppression and noise reduction measures should be taken.
2) Countermeasures for water environment protection
(one) to carry out joint prevention and treatment of water environmental protection.
Fully implement the lake length system, take the long-term mechanism construction of water pollution prevention and control and water resources protection as the starting point, establish a management system of water conservancy and environmental protection cooperation, and promote cross-departmental joint pollution control in Tuohu Basin. Specific measures include:①Establish a joint regular consultation system. By the Bengbu water administrative department in conjunction with the administrative department of environmental protection jointly established Tuohu water environmental protection coordination joint consultation system, held regular joint meetings to coordinate the development of related work.②Establish a regular information notification system and joint monitoring. Strengthen the communication and cooperation of water conservancy and environmental protection system monitoring institutions in water quality monitoring, and carry out joint monitoring on important sections of Tuohu Lake regularly or irregularly. If abnormal monitoring results are found, joint third-party sampling monitoring should be carried out to investigate the causes and solve problems in time.③Conduct regular joint law enforcement inspections.④Establish an emergency linkage system for water environment in Tuohu Basin, coordinate the handling of sudden water pollution incidents, jointly respond to and prevent pollution accidents, and properly handle cross-border water disputes.
(2Deepen the prevention and control of agricultural non-point source pollution
Strengthen the treatment of domestic sewage in rural areas, adopt appropriate technical routes according to local conditions, and disperse when appropriate and concentrate when appropriate. arrive2025In, the main rivers entering the lake and their tributaries on both sides.500The villages involved in the rice range have fully realized sewage treatment and discharge up to standard. Organize the investigation of black and odorous water bodies in rural areas, work out a treatment plan for black and odorous water bodies, take multiple measures simultaneously, take a multi-pronged approach, and take comprehensive measures such as source control and pollution interception, garbage cleaning, dredging and ecological restoration to promote the treatment of black and odorous water bodies in rural areas. We will continue to promote river dredging, bank slope improvement and water system connectivity in rural areas to achieve a smooth flow of living water.
In areas around Tuohu where conditions permit, we will accelerate the pilot project of rotation fallow, carry out the action of replacing chemical fertilizers with organic fertilizers, guide the transformation of fertilization methods and modes, support the construction of specialized unified prevention and control service system, and promote the reduction and efficiency increase of chemical fertilizers and pesticides. arrive2025In, the popularization coverage rate of soil testing and formula fertilization technology for main crops reached.90%Above, the utilization rate of nitrogen fertilizer is improved to40%Above, the coverage rate of unified prevention and control of crop diseases and insect pests has reached40%Above. Promote the construction of ecological ditches, runoff collection and reuse facilities according to local conditions, and effectively prevent and control farmland water pollution.
(three) purse seine culture improvement
2025At the end of the year, the purse seine culture outside Tuohu fishery culture zone will be completely dismantled, and the aquaculture outside the culture zone will not be issued and charged. The purse seine culture in the culture zone needs to be cleaned up and rectified, and the ecological and healthy aquaculture technology will be promoted. Promote the fishermen’s ashore project. Adhere to local conditions, make full use of the existing policies related to urban and rural housing and social security, support fishermen’s landing and housing projects through multiple channels, and give the province overall and separate support for the land use indicators of new resettlement houses.
(four) Rational development and utilization of tourism resources
The tourism authorities should work out the development plan of Tuohu scenic spot, standardize the development behavior of tourism resources, and avoid disorderly development and blind construction. The development of tourism resources should be combined with the restoration and construction of lake ecosystem, and the destruction of lake ecological environment is strictly prohibited. Sewage and waste generated by tourism projects and activities should be collected and treated in a centralized way, and discharged up to the standard. It is strictly forbidden to directly discharge into the lake, which may not affect the water quality.
The planned measures can obviously promote the stability of lake morphology and improve the safety environment of people’s production and life, and have long-term positive significance for improving lake water quality, increasing the available water resources, restoring and protecting lake species diversity, and improving the natural ecological environment of regions and river basins, which is conducive to the sustainable utilization of lake resources such as fisheries and tourism, and to the sustainable development of regional social economy. The implementation of the plan may affect the original fishery output value and the life of its employees in the short term, and may also affect the water quality and natural environment of a small area of the lake, but these adverse effects are short-term and small-scale, and can be reduced by taking countermeasures. In the long run, it is beneficial to the ecological environment of the whole lake and the economic development of the whole region.
