皖江地区湿地生态服务价值评估

皖江地区湿地是长江中下游流域的重要湿地，也是安徽省水网集中分布区，河流水系众多、湖泊库塘星罗棋布。【研究目的】通过对皖江地区湿地生态服务价值的估算，期望为有关部门进行区域规划和合理利用湿地资源提供科学依据；【方法】在调查和资料收集的基础上，参考Costanza等提出的17项生态系统服务功能，利用市场价值法、资产价值法、影子工程法、旅行费用法等评估方法，对皖江地区湿地9项生态服务价值进行了评估。【结果】表明：皖江地区湿地生态服务总价值为1061.21亿元/a，其中固碳价值最高，达434.22亿元/a，其次是水文调节价值、物质生产价值和净化环境价值，分别达到220.75亿元/a、163.50亿元/a和108.13亿元/a，再次是释放O2价值、供水蓄水价值和休闲旅游价值，最小的是文化科研和栖息地价值；皖江地区湿地直接价值214.84亿元/a，间接价值846.37亿元/a，间接价值远远大于直接价值。【结论】并提出了湿地的固碳功能对于全球气候变暖有很大的影响，应合理开发利用和保护湿地资源。

Evaluation of Wetlands Ecosystem Services Value of the Yangtse River Region in Anhui Province

The wetlands of the Yangtze Region in Anhui Province are very important marshes,which located in the middle and lower reaches of the Yangtze River. This Area is also a distribution of concentrated water network with lots of rivers, lakes and reservoirs. 【OBJECTIVE】Through estimating wetlands ecosystem services value of this region,expect to provide scientific reference for the relevant sector regional planning and rational using of wetland resource;【METHOD】Based on the investigation and data collection, reference 17 items of valuating parameters and methods proposed by Costanza and others (1997), evaluated 9 items of ecosystem services value of the wetlands of the Yangtze Region in Anhui using the market value approach, assets value method, shadow project method and travel cost method and so on. 【RESULTS】The results show that the annual value of the wetlands ecosystem service is about 106.12 billion Yuan RMB, which the carbon storage value is the highest with 43.42 billion RMB; secondly is the hydrological conditioning value, material production value and cleaning up the environment value, respectively reached 22.08 billion RMB, 16.35 billon RMB and 10.81 billon RMB; and thirdly is the release oxygen value, water supply value and leisure tourism value; the last is cultural value and habitat value; the wetland direct value is about 21.48 billon RMB and indirect value is about 84.64 billon RMB, which indirect value is far more than direct value. 【CONCLUSION】At the last present that wetland carbon sequestration has great effect to the global climate warming, human should develop rationally and protect wetland resource.
