改进的AHP在黄河三角洲湿地生态环境质量评价中的应用

Eco-Environmental Quality Appraisal of Yellow River Delta Wetland using the Improved AHP Method

基于层次分析法的基本原理,构建黄河三角洲湿地生态环境质量评价的指标体系,运用改进的AHP确定各个评价指标的权重,从而确定影响黄河三角洲湿地生态环境的重要因素、次要因素及一般因素。结果表明:在黄河三角洲湿地生态环境质量评价中,相关部门在三角洲的洪水调节功能这方面,重视程度相对较高,而在气候调节功能方面,却没有引起足够的重视,这些都为黄河三角洲湿地景观规划、管理和保护提供一定参考依据。

Based on the basic principle of AHP,the index system of ecc-environmental quality appraisal of Yellow River Delta wetland was built in this study. The improved AHP method was used to determine the weight of each appraisal index,and consequently to determine the main fac tors, secondary factors,and general factors which have impacts on the ecc-environment of Yellow River Delta wetland. The results showed that the flood regulation function of the delta had been highly emphasized by the sectors concerned while the climate regulation function of the delta had received little attention, which could provide some references for the landscape planning, management and protection of the Yellow River Delta wetland.
