洪泽湖湿地生态系统服务功能价值评估研究

On Ecosystem Services Valuation in Hongze Lake Wetland

洪泽湖是我国第四大淡水湖,是淮河中下游最重要的湿地,具有多种生态服务功能。本文在分析洪泽湖湿地生态系统主要服务功能的基础上,运用市场价值法、影子功能法、替代费用法等方法,对湿地的各项功能进行价值评估。研究结果表明,洪泽湖湿地生态服务功能的总价值为80.59亿元,其中蓄洪滞洪功能最大,占总服务功能的61.68%。在此基础之上,对洪泽湖湿地资源可持续利用,提出若干有益探讨。

Hongze Lake, as the fourth biggest fresh-water lake in China, is the most important wetland in the middle and lower reaches of Huaihe River with many functions of ecosystem service. This paper analyzes the main ecosystem services of Hongze Lake, and provides monetary evaluations on the function of these services by direct market evaluation, shadow project approach, replacement market method. The evaluation results indicate that the total value of the ecosystem services is 80.59 x 108 RMB, and that the most important ecosystem service is flood regulation, which accounts for 61.68%. Based on the results, some useful discussions have been put forward on the sustainable utilization of the wetland resource.
