摘　　要：指出了山区水土流失易造成山区土地资源破坏、生产力降低、土壤肥力下降、土层变薄、洪涝、干旱、淤积等灾害,导致生态环境恶化,是世界性的生态破坏现象之一。严重的水土流失会导致土地生态系统的退化和崩溃。通过了解北京市山区水土流失现状,对山区水土流失的进行了敏感性分析,找出了北京山区水土流失存在的主要问题,并提出了解决北京山区水土流失问题的对策。以期为北京市山区水土流失提出科学合理的治理措施提供参考。Soil erosion in mountain area as one of the world ecological destruction phenomenon is easy to cause the destruction of land resources, the decrease of productivity, the decline of soil fertility, thinning of soil layer, flood, drought, siltation and other disasters, which results in the deterioration of ecological environment. Serious soil ero- sion will lead to the degradation and collapse of land ecosystem. Through understanding the current situation of soil and water loss in mountainous area of Beijing, this paper carried out the sensitivity analysis of soil and water loss in mountainous area. It found out the main problems of soil and water loss in Beijing mountain area. This paper also put forward the countermeasures to solve the problem of soil and water loss in Beijing mountain areain order to provide guidance for scientific and reasonable measures for soil erosion in mountain areas of Beijing city.
