湖北宣恩贡水河国家级湿地公园 生态系统服务价值评估

湖北宣恩贡水河国家湿地公园的湿地类型为库塘湿地和永久性河流湿地,具有多种重要的湿地生态系统功能。以湖北宣恩贡水河国家湿地公园为研究对象,利用遥感和地理信息系统技术,从水质净化、保持生物多样性、旅游休闲、涵养水源、保持土壤、气候调节、科研教育等9项生态系统服务价值进行研究;采用市场价值方法法、影子工程方法和成本参照方法等,对各项生态系统服务价值进行估算。结果表明,湖北宣恩贡水河国家湿地公园生态系统服务功能总价值为15.4×108元,单位面积价值约为275万元/hm2,其中水源供给、水质净化、调蓄水源、气候调节、旅游休闲、科研教育是湖北宣恩贡水河国家湿地公园湿地生态系统的主导服务。研究结果有助于人们更加直观地认识湿地生态系统服务的重要性,同时也为湿地生态系统的保护和管理以及合理的开发利用提供科学的依据。

Gongshuihe National Wetland Park, Xuan ''en, Hubei Valuation of ecosystem services

The wetland types of Gongshuihe National Wetland Park in Xuan ''en, Hubei Province are pond wetland and permanent river wetland, which have many important wetland ecosystem functions. With Gongshuihe National Wetland Park in Xuan ''en, Hubei Province as the research object, nine ecosystem service values, including water purification, biodiversity conservation, tourism and leisure, water conservation, soil conservation, climate regulation, scientific research and education, were studied by remote sensing and GIS technology. The market value method, shadow engineering method and cost reference method are used to estimate the value of each ecosystem service. The results showed that the total value of ecosystem services in Hubei Xuengong Shuihe National Wetland Park was 15.4×108 yuan, and the unit area value was about 2.75 million yuan /hm2, among which water supply, water purification, water regulation and storage, climate regulation, tourism and leisure, scientific research and education were the leading services of the wetland ecosystem in Hubei Xuengong Shuihe National Wetland Park. The research results help people to understand the importance of wetland ecosystem services more intuitively, and also provide scientific basis for the protection and management of wetland ecosystem and rational development and utilization.
