【 摘 要 】

Weishan Lake is one of the four lakes in the Nansi Lake and an important water transport hub for the east route of the South-to-North Water Transfer Project. The water quality study of Weishan Lake is conducive to a comprehensive understanding of the water quality and ensure the smooth progress of the South-to-North Water Transfer Project. This paper uses the water quality comprehensive pollution index evaluation method to analyse the water quality of Weishan Lake, and uses ArcGIS drawing software to spatially distribute the concentration of CODMn, NH3-N, TP, TN and SS in Weishan Lake water quality monitoring. Visualize to analyse the maximum impact factor for each space. At the same time, this paper combines the water quality evaluation results of Weishan Lake and the cause of water pollution, and puts forward the control countermeasures suitable for the pollution control of the basin, which provides a basis for the Weishan Lake watershed management and the realization of the water quality target of the South-to-North Water Diversion Project.
