摘要： The quantification of nitrogen and phosphorus nutrient loads is the primary task for the control of non-point pollution. In this study, the data between 2006 and 2011 were collected and analyzed in Haikou City. The results showed that the major agricultural non-point source structure was composed of nitrogen and phosphorus and the order was fertilizers > living sewage > animal feces in last 5 years in Haikou City. Constitute changes of nitrogen and phosphorus in agricultural non-point source suggested that the nitrogen and phosphorus contribution rate of fertilizer on agricultural non-point source declined, while residents of sewage, animal feces annually increased.
