英文摘要	Total nitrogen (TN) and total phosphorus (TP) flowing into water were calculated with the method of pollution discharge coefficient to determine non-point source (NPS) pollution of Songyuan City in the year of 2000, 2005 and 2008. The pollute sources included five categories: chemical fertilizer, livestock waste, household pollution, soil and water loss, and farmland waste. Results showed that: The equivalent pollution load of NPS following into water bodies in 2000, 2005 and 2008 in Songyuan City were 40907.61 m3/a, 42112.51 m3/a and 42682.25 m3/a, respectively. Chemical fertilizer, livestock waste and household pollution were the primary pollute sources and they accounted for more than 95% of the NPS pollution. In terms of the total amount of NPS pollution, it was gradually intensifying. However, as NPS pollution has been paid increasing attention, its growth rate has declined in the duration from 2000 to 2008.; EI; 0; SUPPL. 1; 92-100; 18
