| 摘 要： | 为了解岗南水库流域水土流失现状，以岗南水库上游典型小流域为研究区域，通过遥感手段和野外调查进行信息采集，在GIS支持下，根据通用土壤流失方程（USLE）模型对数据实施运算，估算小流域土壤流失量。结果表明，自然背景状态下，研究区年均土壤流失量为50.23 t/（km^2·a）。

| Abstract: | In order to understand the soil erosion status in the basin of Gangnan Reservoir, with the typical small upper basin of Gangnan Reservoir, the information was collected by using the methods of RS and field survey. Under the support of GIS, the data were calculated according to USLE model. The soil loss amount of small basin was estimated. The results showed that the annual mean soil loss amount in the study area was 50.23 t/(km~2·a) under the general conditions. |
