N in the main form of nitrate through the subsurface runoff was put into the stream, the vegetation-covered riparian had high on the nutrient in the soil water.
溪流相邻高地通过地下径流向溪流中N素的输入，主要是以硝态氮的形态通过土壤水的输入；
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。
