摘要：

The loss of non-point source pollution of Shiyan City was calculated in 2002, 2004, and 2006 with the method of pollution discharge coefficient; Based on social and economic data of Shiyan City and stepwise regression analysis, the relationship between economic, social factors and non-point source pollution loss was studied. The results showed that: Pollutants of total nitrogen(TN) and total phosphorus(TP)in Shiyan City showed an upward tendency and regional difference in 2002, 2004, and 2006. Agricultural output value and orchard area were the main driving factors of TN loss; the output value of fishery, the output value of agriculture and land area were the main driving factors of TP loss.
