Trend analysis of water quality changes and countermeasures at the Taocha Canal Head
摘要
Abstract
As the"water tap"of the Middle Route of the South-to-North Water Diversion Project,the water quality at the Taocha Canal Head is directly related to the water and ecological security of hundreds of millions of people in North China.Currently,the water quality at the Taocha Canal Head is generally excellent,though fluctuations in its classification still occur.Analysis of monitoring data from 2017 to 2024 for the Danjiangkou Reservoir and the Taocha Canal Head section shows that the water quality at the Taocha Canal Head has remained at Class I(evaluated according to river water quality standards),while indicators such as total phosphorus,dissolved oxygen,and permanganate index occasionally exceed Class I standards.Total phosphorus,dissolved oxygen,and permanganate index are the key indicators affecting the water quality classification at the Taocha Canal Head section,whereas inflow discharge,water level,and water temperature are the main environmental factors driving water quality variations.In addition,algal proliferation and local hydrodynamic conditions may intensify water quality fluctuations.Based on these findings,management measures are proposed,including optimizing the water quality and quantity monitoring system,strengthening the application of the Digital Twin Hanjiang River,enhancing comprehensive basin risk control,and deepening studies on water quality evolution.These measures provide a scientific basis and practical reference for maintaining excellent water quality at the Taocha Canal Head section and strengthening water quality security in the water source area of the Middle Route of the South-to-North Water Diversion Project.关键词
