汉江中下游湿地面积减小后的生态系统服务价值损失

The Loss of Ecological Service Value after Wetland Area Decreasing in Middle and Lower Reaches of Hanjiang River

鄂北地区水资源配置工程2018年建成并实施后,将从丹江口库区引水7.70×108m3,为了研究其对汉江中下游干流河段湿地生态系统服务的影响,采用模糊数学方法,选择汉江中下游5处重要湿地,对工程实施前后湿地生态系统服务价值进行定量评估。结果表明,工程实施后,汉江中下游湿地面积减小64.8 hm2,生态系统服务价值损失931×104元。

The water resources allocation project in Northern Hubei province will be set up in 2018, it will draw about 7.70×10^8m3water resources from Danjiangkou Reservoir. According to the method of fuzzy mathematics, 5 important wetlands in middle and lower reaches of Hanjiang River will be affected due to the project. After the project implemented, the area of the wetlands will be reduced 64.8 hm2. And the value of wetland ecosystem service will lose 9.31 million yuan.
