Pollution loading of dissolved N and P in ChaoHu lake watershed could be evaluated through export model of N and P after annual runoff volume was work out according to SCS model.
流域溶解态N、P污染负荷估算是由SCS模型得到流域年径流量，然后由溶解态N、P输出模型计算得出。
This implied that the relatively high risk of N and P losses through leaching and runoff in Taihu Lake region during season of wheat growth could probably occur after earing stage of the wheat growth.
太湖地区小麦生长季节土壤氮磷向水体迁移的环境风险在小麦抽穗期后相对较高。
