基于AHP法白洋淀湿地生态评价

Ecological Evaluation of Baiyangdian Wetland by AHP Method

以白洋淀湿地为研究对象,采用层次分析法对湿地进行生态评价。结果表明:湿地最主要的功能是生态服务功能(0.64);其次是生态保护功能(0.26);最次是资源功能(0.1)。单项指标中最重要的是缓洪滞沥功能(0.31),最次为土地资源功能(0.004)。最后,通过计算湿地综合评价指数(CEI=0.58),根据自然保护区生态环境质量分级标准,得到湿地生态质量等级为一般。

As the object of study, Analytic Hierarchy Process（AHP） method was used for the Baiyangdian wetland ecological evaluation. The evaluation results show that the weights of evaluation indexes of the ecological service function is 0.64, the ecological protection function is 0.26, and the resources function is 0.1. The weight of homogenization flood function is 0.31. The weight of land resources function is 0.004. They are the maximum and minimum value in the single index divided. According to ecological evaluation criteria and standards for nature reserve, by calculating the comprehensive evaluation index （CEI=0.58） obtains the ecological quality grade is general.
