On the 5th, the colorful Yunnan Protection Action website of Yunnan Provincial Environmental Protection Department announced the "12th Five Year Plan" for the comprehensive prevention and control of water pollution in plateau lakes in Yunnan Province, and widely solicited opinions from all sectors of society on the ideas, objectives, tasks, project settings, and whether the pollutant reduction is scientific and reasonable of the "12th Five Year Plan" for the comprehensive prevention and control of water pollution in plateau lakes. The publicity period is from March 6, 2012 to March 22, 2012.
Water environment quality of Fuxian Lake: the water nutrition level continues to increase, and the pollution from farmland non-point source, rural sewage, livestock manure increases, and sewage treatment.
The objectives of the "12th Five Year Plan" governance plan: a total of 4.642 billion yuan will be invested in the seven major categories of comprehensive prevention and control of water pollution in Fuxian Lake. By the end of 2015, the average water quality of the whole lake will be stable and maintain Class I surface water quality. After governance, the water quality of the estuary sections of the seven main rivers into the lake will reach Class IV, and after the industrial structure adjustment, pollution control and emission reduction measures, The output of structural pollutants decreased significantly. Establish a system of lake ecological environment protection and management, and improve the ecological environment of the basin.
Water environment quality of Erhai Lake basin: the water body is at the initial stage of eutrophication, and algal blooms can be seen every year in local lake bays (especially the northern lake bay) and downwind banks. The pollution load of Erhai Lake basin mainly comes from rural domestic pollution, livestock and poultry breeding pollution, farmland non-point source pollution, urban domestic pollution, etc.
The goal of the "12th Five Year Plan" is to ensure the stability of the water quality of the whole lake to reach the Class III water quality standard and strive to reach the Class II water quality standard by implementing comprehensive treatment and watershed management in the key areas affected by the pollution of Erhai Lake. Take Miju River, the three rivers in the north, and Shibaxi small watershed in Cangshan as the key pollution prevention and control area, and carry out regional industrial structure adjustment, key pollution source system treatment, low pollution water purification system construction, and clean water production system construction of rivers entering the lake; Strengthen river basin management and carry out the construction of ecological civilization system.
Water environment quality of Qilu Lake: the main pollution sources are rural domestic sewage and farmland non-point source pollution. The concentration of total phosphorus and total nitrogen in the water body remained high, showing a moderate eutrophication state; The permanganate index of the water body is also quite high, and the water quality is poor V. A large number of submerged vegetation died out, and the ecological function gradually lost.
The goal of the 12th Five Year Plan is to significantly reduce the pollution load into the lake. By the end of 2015, the overall water quality will reach Class V of surface water and strive to reach Class IV; The main water quality indicators of Hongqi River and Zhonghe River, the main rivers entering the lake, reach Class V of surface water.
Water environment quality of Lugu Lake: the water quality of the lake is generally good, but the water quality of the main rivers entering the lake is polluted to a certain extent. Tourism pollution has become the main source of pollution in the basin, and the pollution interception and treatment system along the lake is not perfect; The terrestrial ecosystem of the basin is fragile, and the problem of water and soil loss cannot be ignored; Rural agricultural non-point source has always been an important source of pollution in the basin. The village sewage collection facilities are backward and the treatment project is single; The land use structure of the lakeside buffer zone is unreasonable, the construction of the lakeside zone lags behind and is not large-scale, and the pollution pressure of production and living in the nearshore zone is prominent.
The goals of the "12th Five Year Plan" governance plan: by the end of 2015, the water quality of Lugu Lake will be stable and maintain the Class I surface water quality goal, and the main rivers entering the lake will reach the Class II surface water quality goal; The pollution sources in tourism and tourist reception areas have been comprehensively reduced and transferred to other river basins, with a reduction rate of more than 80%. The discharge of rural agricultural non-point source pollution load has been reduced by more than 30%, and the rate of water and soil loss has been reduced by more than 10%.
The water environment quality of Xingyun Lake: the nutrient status shows a sharp upward trend, and the pollutants entering the lake mainly come from farmland runoff pollution, livestock manure pollution, rural life pollution, etc.
The objectives of the "12th Five Year Plan" governance plan: by the end of 2015, the declining trend of water quality will be significantly curbed, and the water quality and water ecology will be gradually improved, eventually reaching Class V and striving to reach Class IV level; The treatment and resource utilization of livestock manure pollution in the dam area along the lake and the "two pollutants" in the villages along the lake have basically controlled the major pollution sources in the basin and the pollution around the lake; The main rivers entering the lake were comprehensively renovated, the water quality pollution of rivers was basically controlled, and the pollution load into the lake was significantly reduced; Control the cyanobacteria bloom and "internal load" in Xingyun Lake. Establish a comprehensive management system for the ecological environment of the lake basin to realize scientific and comprehensive management and protection of the basin.
Environmental quality of Yangzong seawater: the water quality of the lake is Class IV, and the main items exceeding the standard are total phosphorus and arsenic. In 2010, the water quality of the main rivers entering the lake was Class V. The agricultural non-point source pollution and industrial pollution in the basin were the main sources of pollutants.
The objectives of the "12th Five Year Plan" governance plan: strictly control tourism and industrial pollution, significantly reduce agricultural non-point source pollution, and further reduce the concentration of arsenic pollutants in lake water and the diffusion impact of terrestrial arsenic pollution sources through scientific and effective measures. By the end of 2015, the water quality of Yangzonghai will be stable at Class III, striving to reach Class II, and the main rivers entering the lake will be stable at Class III or above.
Environmental quality of Chenghai water: the water pollutants mainly come from agricultural production and rural life, followed by urban pollution, and industrial pollution is the least. In 2010, the average nutritional status index was 43.2, which was in a moderate nutritional status.
The objectives of the "12th Five Year Plan" governance plan: by 2015, the discharge of major pollutants will be effectively controlled, and the ecological environment will be significantly improved. The water quality of Chenghai Lake, except for PH and F ions, will remain stable at the Class III water quality standard for surface water environmental quality, strive to reach the Class II standard, and maintain the nutrition level at the mesotrophic level.
