安庆沿江湖泊湿地是长江中下游淡水湿地的重要组成部分,是"东亚—澳大利亚鸻鹬类保护网络"中的重要一环,湿地资源十分丰富。本文运用生态经济学中的市场价值法、碳税法、影子工程法等评价方法,依据安庆沿江湖泊湿地特点对它的经济功能价值包括水资源价值、渔业资源价值、土地资源价值等;环境功能价值包括科考旅游价值、涵养水源价值、调节气候价值、调蓄洪水价值、净化水质价值等;社会文化价值等进行货币化评估;最后计算出安庆沿江湖泊湿地服务功能总价值为142.49×108元,其中渔业资源价值最大,占安庆沿江湖泊湿地生态系统服务价值中的比例为18.91%,其次是调蓄洪水价值占总生态系统服务价值的17.17%。本文可为安庆沿江湿地的可持续利用提供科学参考。

Wetlands of the nature reserve along the Yangtze River in Anqing City,as a part of wetlands in middle and lower reaches of Yangtze River,are the post station of migratory birds moving from East Asia to Australia. In this paper,the economic value of lakes and wetlands along the Yangtze River in Anqing,including water resources value,fishery resource value,land resource value,research and culture value,scientific expedition and tourism value,was studied with market value method,carbon tax method,shadow engineering approach and so on,according to its characteristics.Second,the environmental-function value was evaluated,such as water conservation value,regulation climatic value,flood diversion and storage value,water purification value and so on.Then,the social cultural value was evaluated.Lastly,the total value of different service functions of lakes and wetlands along the Yangtze River in Anqing was 142.49×108 yuan.The fishery resource value was most valuable in those functions,with a rate of 18.91% in service value of lakes and wetlands along the Yangtze River in Anqing eco-system,followed by the flood diversion and storage value,accounting for 17.17%.As a result,the above data can provide scientific reference for sustainable utilization of the wetlands along the Yangtze River in Anqing City.
