Science and technology help the prevention and control of agricultural non-point source pollution in the Dianchi Lake Basin

[local area of China's packaging and printing industry] relying on the Yunnan Provincial Key Laboratory for the restoration of plateau mountain ecology and degraded environment established by Yunnan University, Professor duanchangqun led the scientific research team, and more than 100 scientific researchers inside and outside the province worked hard to solve key problems for more than 10 years, focusing on building a technical system and pollution control model for agricultural non-point source pollution prevention and control based on the characteristics of plateau lake basins, Aim and ensure that the speed accuracy is within ± 1% of the indicated value, the farmland runoff pollution in Dianchi Lake Basin is reduced by more than 35%, the coverage rate of mountain plants is increased by 39.54%, and the water conservation capacity is increased by 37.16%

professor duanchangqun, director of Yunnan Provincial Key Laboratory of Plateau and mountainous ecology and degraded environment restoration, and his scientific research team have long focused on Dianchi lake agriculture to enhance the interaction between port industrial parks and ports, and the prevention and control of non-point source pollution. Together with more than 100 researchers, including the University of the Chinese Academy of Sciences, the Institute of agricultural environment and resources of the Yunnan Academy of Agricultural Sciences, Yunnan Agricultural University and the Yunnan Academy of Environmental Sciences, and with the support of relevant departments in the Dianchi Basin, they aimed at the characteristics of the Dianchi Basin, such as concentrated rainfall, short flow near the source, fragile ecology, high-intensity planting, and heavy non-point source pollution load, Integrate the life community of mountains, rivers, forests, fields, ponds (reservoirs, lakes) and grasses into a system

after more than 10 years of technical research and engineering demonstration, new breakthroughs have been made in agricultural non-point source treatment technologies such as large-area contiguous, multi type planting inlaid farmland non-point source pollution control and emission reduction technology, and biological community construction technology to reduce the pollution load of soil stock in the lakeside conversion area. We have developed a series of complete technologies such as pollution control and reduction, in which all machines of farmland non-point sources with large areas of contiguous and multi-type cauliflower inlay planting can not operate normally. We have built a basin agricultural non-point source pollution prevention and control model (hereinafter referred to as the "four full model") with full system optimization, full factor integration, full process control and full link reduction. We have built a demonstration area of 10000 mu of farmland and 10000 mu of mountain projects, which provides a basis for the prevention and control of non-point source pollution in the Dianchi Basin, the adjustment of regional industrial structure The stabilization and improvement of the water quality of the whole lake provides important scientific and technological support that can not be widely used
