| 摘 要： | 密云水库是当前北京唯一的一个地表饮用水源.上游的水土保持对于水源涵养和水库水环境具有重要意义.本文结合国内通用土壤流失方程（RUSLE）各因子研究的最新成果,首次在该模型的应用中采用了符合北京山区降雨量变化和土壤质地实际情况的因子计算方法,重点针对R、K因子的算法进行了选择并结合ArcGIS软件的空间分析和插值技术,得出了研究区域内水土流失总量和各乡镇的具体流失量进而识别出石城镇和古北口镇为水土流失的重点区域,应该加强水土保持的力度.

| Abstract: | Miyun Reservoir on the Chaobaihe River is one of the main water suppliers for Beijing.Water and soil losses are the main reasons responsible for the reservoir sedimentation.The model,which combines the latest research results of Universal Soil Loss Equation(USLE) in China,firstly is applied accord with the Beijing mountain rainfall and soil texture mai situation,R,K factor algorithm has been choosed Specially.Combining with ArcGIS interpolation technology and spatial analysis shows that the total soil erosi... |
