Abstract:

Nansi Lake serves as a crucial regulating lake and water diversion channel for the East Route of the South-to- North Water Diversion Project, playing a strategic role in maintaining regional ecosystem balance. In Jining Municipality, it continuously improved water pollution prevention and control in Nansi Lake, leading to sustained water quality improvement and ensuring the continuous northward flow of "clear water". This paper analyzes problems such as lake eutrophication, total pollutant discharge in the basin, sudden environmental risks, and treatment of emerging pollutants. It also proposes countermeasures for urban and agricultural nonpoint source pollution, aiming to provide references for the protection and management of Nansi Lake and other rivers/lakes.
