Abstract:: The Taihu Lake Basin is one of the most important water source areas in the Yangtze River Delta region. Due to different land uses in the water sources area, non-point source pollution is still serious. To control the losses of nitrogen(N)and phosphorus(P), we took the Fushi Reservoir catchment in Anji, an important water source in the Taihu Lake Basin, as the test plot, and explored the characteristics of N and P losses with different land uses through field runoff observations. The results showed that:(1)the average loss of TN in economic forests in this region was the largest, which was 3.21 mg/L; the average loss concentration of TP decreased in the order: economic forest(0.13 mg/L)> white tea(0.09 mg/L)>natural land(0.07 mg/L)= secondary forest(0.07 mg/L); clearly, secondary forests could effectively reduce the losses of N and P;(2)rainfall intensity and rainfall volume were the main rainfall factors affecting N loss in this area;(3)nitrate-N and DP were the main forms of N and P loss;(4)N pollution was the key factor that impacted water quality, so it was necessary to strengthen the control of N loss. Obviously, optimizing the land uses of water source areas and constructing well-structured water source shelter forests are helpful to improve the environment of water source areas and ensure drinking water safety.
