成都市环城生态区人工湿地生态系统服务评价

人工湿地生态系统服务评价对人工湿地的规划和建设具有重要意义。以成都市环城生态区为研究对象,基于层次分析法和模糊隶属度函数法构建人工湿地生态系统服务综合评价体系,并进行生态系统服务评价。结果表明:成都市环城生态区内人工湿地生态系统服务评价指数为0.517,整体服务水平良好,能够在一定程度上发挥人工湿地的生态服务功能。其中物质生产服务、生态调节服务和文化科研服务分别为0.0511、0.1210和0.3447,各类服务贡献率分别为10%、23.4%和66.6%。评价结果不仅能提高公众和管理部门对成都市环城生态区的认识,也有助于进一步推进成都市人工湿地的规划和建设工作。

Evaluation of Ecosystem Services of Artificial Wetlands in the Ecological Zone Around Chengdu City

Evaluation of ecosystem services is of great significance to the planning and development of constructed wetland.The ecosystem services of artificial wetlands in the ecological zone around Chengdu City was evaluated using the comprehensive evaluation system of ecosystem services of artificial wetland based on the methods of analytic hierarchy process and fuzzy membership function.The evaluated index of ecosystem services of the artificial wetlands in the ecological zone around the city is 0.517,indicating that the ecosystem service is good in general and can play the ecological function of artificial wetland to a certain extent.The indices of services of material production,ecological regulation,and culture and science were respectively 0.0511,0.1210 and 0.3447,representing a contribution of 10%,23.4%and 66.6%of the total service.The evaluation is helpful to further promote the planning and construction of artificial wetlands in Chengdu and provides new ideas for the related studies of artificial wetlands.
