小流域N、P污染负荷的构成比重研究

The pollution of nitrogen and phosphor constitute at small watershed

对浙江省宁海县颜公河流域 N、P污染物负荷的构成比重进行了研究 ,提出了农业非点源污染造成水体污染的严重性。采用美国农业部的 Ann AGNPS模型模拟计算流域中农业面源污染的 N、P负荷 ,并对模型模拟计算的可靠性进行了验证。

The studies on nitrogen and phosphor pollution constitute in Yangonghe watershed at Ninghai county, Zhejiang province were presented. The results show that agricultural non point source pollution is the most important pollution,which computed by AnnAGNPS model and tested by survey data.
