| 摘 要： | 以流溪河流域为例,运用输出系数模型对该流域1990与2008年的非点源污染负荷进行了估算,并初步探讨了流域非点源污染负荷发生变化的原因。结果表明：1990-2008年间,流溪河流域的非点源BOD/COD/TN/TP污染负荷都呈快速增加的趋势,其中BOD/COD增幅较大;流域非点源污染负荷的增加主要是由于土地利用类型的改变、GDP的增长和人口的增加引起的。

| Abstract: | Now,the study of non-point source(NPS) pollution of large and medium-sized basin is still not common.In this paper,spatial-temporal changes of non-point source pollution in Liuxi river watershed over the last 18 years were studied based on the simulation of its load by export coefficient model.The results indicated that the NPS pollution load caused increased year by year,mainly due to land use change and rapid increase of GDP and population. |
