【摘要】 湿地是具有多功能的独特的生态系统,对其生态服务功能进行评价.为管理和保护湿地提供科学的依据。以白洋淀湿地为研究对象,采用市场价值法、权变估价法、生产成本法、影子工程法,模糊数学法、旅行费用法、生态价值法等.对该湿地生态系统服务功能进行了价值估算。经计算,该湿地生态系统服务功能的总利用价值为1 75 910.1×104元/a,其中,维持白洋淀湿地生态系统的完整性和自然过程的服务功能最人为68 200×104元/a,柄息地价值最低为92×104元/a。扎最后,对该湿地生态系统服务功能的价值构成进行了分析和讨论。更多还原

【Abstract】 The wet land has its own multi-funtional and unique ecosystem and the evaluation of its ecological service function provides the scientific basis for its managemend and protection. This paper, by adopting the market value method, tact evaluation method,production cost method, reflection engineering method, fuzzy maths method, travel cost method and ecological value method, takes the Baiyangdian Lake as the object of study to estimate the value of its wet land ecosystem and its service function. The estimated total usable value of the wetland ecosystem service function is RMB 175910. 1×104yuan/year, among which, maximum RMB 68200×104yuan/year is used to maintain the miegrity and the natural service process of the wetland, and minimum RMB 94×104yuan/year is used to maintain the habitat. This paper finally analyses and discusses the value formation of the wetland ecosystem service function.更多还原
