基于AHP法的湿地生态基础设施评价研究——以六盘水市双桥水库为例

Study on Evaluation of Ecological Infrastructure Quality of Wetland Based on AHP——Case of Shuangqiao Reservoir in Liupanshui City

湿地生态基础设施是关系到湿地生态安全和健康的问题,其评价尚没有统一的指标和方法。从生态基础设施的概念出发,根据六盘水市双桥水库的环境特征和已有的研究成果,以生态基础、生态功能和社会经济3个系统为依据,构建评价指标体系,采用层次分析法和综合指数法建立评价模型,对其生态基础设施品质进行评价,结果表明双桥水库生态基础设施质量为一般状况。并对影响库区生态基础设施质量的主要原因进行分析,以期为湿地生态基础设施建设提供科学参考。

Ecological Infrastructure of wetland concerns the ecological security and health of city. There has not uniform evaluation index and method. Starting from the conception and connotation of ecological infrastructure, the evaluation index system is established on the basis of ecological basis, ecological function and social economy according to the environmental characteristics and the existing research results in the Shuangqiao reservoir in Liupanshui city. Analytic Hierarchy Process （AHP） and the method of com- prehensive index evaluation are applied to establish the evaluation model. Then, it is used to study the quality and evolvement charac- teristic of ecological infrastructure in Shuangqiao Reservoir in Liupanshui. The result shows that the quality of ecological infrastructure of Shuangqiao Reservoir in Liupanshui belongs to common grade. And the main cause of the impact on ecological infrastructure quality is analyzed, which can provide a scientific basis for the wetland ecological infrastructure construction.
