摘要
密云水库作为北京市的主要水源地,其水质的保护和水库安全对北京市起着极为重要的作用。密云水库上游的水土流失情况对于首都地区的生态安全具有重要影响。本文根据研究区的土壤侵蚀特点和具体情况,从土地利用、坡度、土壤类型和人口等方面进行研究,探讨研究区土壤侵蚀的空间分布特征,为该地区的水源保护和侵蚀防治提供科学依据。
Miyun Reservior, as the most primary water supply source of Beijing city, its water quality protection and safety plays an improtant role for Beijing city. Water and soil loss in the upper reaches has great influence on ecological safety in capital area. Based on soil erosion features and actual condition of the reseach area, combining with land use, slope, soil type and the population, the article discussed the characteristics of soil erosion spatial distribution in the reseach area. The results will provide the area with scientific foundation of water source protection and soil erosion control.
