摘要
云南高原湖泊山区小流域是湖泊重要的生态屏障和主要的清洁水源涵养区,随着社会经济的发展,其水环境呈现日益恶化趋势。以抚仙湖山区小流域的典型代表尖山河为例,在对其水环境现状及其污染成因分析的基础上,从林业生态建设、水土流失防治、农业面源污染控制、农村环境综合整治、主河道入湖河水净化等方面探讨了小流域水环境治理的对策。
Smallriverwatersheds are the main water sources and important ecological barriers of lakes.Water environment of the watersheds are deteriorating along with social and economic development.In this paper,a typical small watershed around Fuxian Lake,the Jianshan river watershed was studied as an example.Firstly,the status of water environment and the causes of pollution were analyzed.Then countermeasures on environmental management in the watershed was discussed with a focus on forestry ecological restoration,soil erosion control,agricultural nonpoint source pollution control,comprehensive improvement of the rural environment,and water purification of lake inlet.The paper gave some implication for the management of similar river watersheds of plateau lakes in Yunnan province.
