Abstract: 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.
