The article discusses pollution sources and ways to control the eutrophication of Taihu Lake. Researchers focused on factors like TN, TP, and CODCr to understand the main environmental issues. They identified different pollution sources and how pollutants enter the lake. The study suggests controlling TN, TP, and CODCr to address the problem. The researchers proposed ecosystem regulation, nutrient transfer, and building ecological zones to control eutrophication in Taihu Lake.
