| 摘 要： | 磨盘山水库是哈尔滨市的重要地表饮用水源,水库水质的好坏直接关系到哈市人民的生产和生活。通过划分不同类型的非点源污染发生区,选定典型区域,应用水土流失方程(USLE)估算出吸附态氮磷的潜在侵蚀量。通过率定输沙比和富集比,得出吸附态氮磷污染物实际的年入库量。结果表明,2006年通过地表径流作用,进入库区的吸附态氮的量为168.88 t,吸附态磷的量为128.67 t。

| Abstract: | As an important water-source region,Mopanshan reservoir plays a crucial role in people＇s daily life and work for Harbin＇s people.According to different occurring regions of non-point pollution,we apply Universal Soil Loss Equation（USLE） to typical areas and reckon the potential erosion load of absorbed nitrogen and phosphorus.On the basis of sand deliver rate and enrichment rate,we may figure out the annual load of absorbed nitrogen and phosphorus flowing into the reservoir.The results show that 168.88t absorbed nitrogen and 128.67t absorbed phosphorus flow into reservoir in 2009. |
