摘要
湿地是具有多功能的生态系统,对其生态服务功能进行评价是管理和保护湿地的重要途径。以白洋淀湿地为研究对象,通过调查和实验,综合运用经济学、资源学和生态学方法,对该湿地生态系统服务功能进行了价值评估。经过计算,该湿地生态系统服务功能的总利用价值为71792.7×104元/a,其中,直接利用价值为34678.4×104元/a,间接利用价值为37114.3×104元/a。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。
The wetland is a particular ecosystem with multi-functions. The evaluation of wetland ecosystem value is an important way to manage and protect wetland. Through investigation and experiment in the Baiyangdian Lake wetland, by synthetically using economic, resource science and ecology method, the value assessment of wetland ecosystem has been conducted. The results showed that the total use value of the wetland ecosystem services is 71 792. 7×104RMB/a, in it, the direct value is 34 678. 4×104 RMB/a, the indirect value is 37 114. 3X104 RMB/a. Finally, the value constitution of the Baiyangdian Lake wetland ecosystem service has been analyzed and discussed.
