摘　　要：草海是我国最大的高原淡水湖泊,因特殊的地理位置关系,草海湖泊接纳了来自区域内生产生活产生的各种污染物质,加之草海作为一个脆弱的生态系统,对抗外界干扰的能力差,在流域强烈的外界人类活动干扰下,草海脆弱的生态环境逐渐退化。在草海高原湿地,面对巨大的农业生产与旅游开发中的人为干扰,急需对生态环境进行改善和治理。综合分析了造成草海地区主要环境污染的污染源、污染物的种类及分布特征,并对草海湿地污染情况进行评价,以期为草海湿地土壤环境的保护提供理论依据。Caohai is China＇s largest plateau freshwater lake. Due to its special geographical location,the lake accepted all kinds of pollutants from production and life in the region. As a fragile ecosystem,its anti-interference ability is poor,and under the strong disturbance of human activities,the ecological environment is gradually degrading.The wetlands are faced with great agricultural and tourist pressures,so it is urgent to improve and control the ecological environment. In this paper,we analyzed the main pollution sources,pollutant types and distribution characteristics,and evaluated the pollution status,so as to provide theoretical basis for the protection of Caohai.
