摘要: 阳宗海是云南省九大高原湖泊之一，在区域生态维持和经济发展上有着不可代替的作用。本文采用成果参照法、市场价值法、替代法、条件价值评估法等方法对阳宗海水产品提供、生物多样性保护、水源涵养、土壤保护、气候调节、废物处理、科研文化、休闲娱乐等方面的价值进行了评估，评估结果为：阳宗海湖滨湿地生态系统服务总价值为6.7042亿元/a，其中，休闲娱乐功能的服务价值最高，为5.29亿元/a，占总服务价值的78.91%，废物处理和气候调节功能的服务价值次之，研究结果表明了阳宗海湖滨湿地对控制污染源、改善水质、维护区域生态体系有着重要作用。

Abstract: Yangzong Lake is one of the nine high plateau lakes in Yunnan Province. It has an irreplaceable role in regional ecological maintenance and economic development. In this paper, the results reference method, market value method, substitution method and conditional value evaluation method are used to evaluate the value of aquatic product supply, biodiversity conservation, water conservation, soil protection, climate regulation, waste treatment, scientific research culture, recreation of Yangzong Lake. The evaluation results show that total value of Yangzong Lake wetland ecosystem service is 0.67042 billion Yuan a year, among which, the value of recreational and recreational functions is the highest, which is 0.529 billion Yuan a year, accounting for 78.91% of the total service value. The value of waste treatment and climate regulation ranks the second. The results indicate that Yangzong Lakeside wetlands play an important role in controlling pollution sources, improving water quality and maintaining regional ecological systems.
