Abstract:: In order to examine the sources of agricultural nonpoint source pollution in Suzhou Taihu Lake Basin area for the study, based on analysis of the characteristics of the area of agricultural industrialization, agriculture point source pollution of nitrogen and phosphorus pollution load represented by the Taihu Lake Basin farming, aquaculture, large-scale poultry industry were investigated, and the nitrogen and phosphorus pollution load was calculated. The results showed that farming, aquaculture, livestock and poultry breeding industry emissions of nitrogen and phosphorus pollutants were: TN 2 344.12 t; TP 123.78 t;TN 12 915.72 t; TP 2 560.76 t; TN 2 348.98 t; TP 460.81 t in Suzhou City in 2011. It was suggested that the amount of nitrogen and phosphorus pollutants decreased in the order: aquaculture > planting > poultry, aquaculture pollutant emissions of nitrogen and phosphorus are more than four times of the sum of farming and poultry, aquaculture is the main sources of pollution of the Taihu Lake Basin surface. In order to improve the water environment in Taihu Lake Basin, it is recommended to reduce the size and density of aquaculture, decrease the amount of nitrogen and phosphorus pollutants into the lake.
