Under base employ of the coated urea, the total N concentration of farm surface water was near the contract level, and the possibility via runoff was very little.
结果表明，包膜尿素在基施情况下，田面水总氮浓度始终接近对照水平，通过径流损失的可能性很小。
It was showed that the mean concentration and accumulated amounts of runoff losses of nitrogen were highly correlated with N-application rates.
结果显示，随施氮量增加，农田径流液中氮素的平均浓度和氮素径流累积流失量提高，两者间呈显著正相关。
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。
