基于熵权灰色关联分析的湿地补水项目综合效益评价

为了对湿地补水项目带来的效益进行综合评价,通过对我国湿地生态现状的调研和分析,构建了包含3个一级指标、12个二级指标的湿地补水项目综合效益评价指标体系,并将熵权法与灰色关联分析相结合的模型应用于湿地补水项目评价。为了从实践角度说明评价方法的可行性,选取3个典型的湿地补水项目,采用专家打分的方法获得原始数据并进行实证分析。结果表明:所构建的指标体系合理,熵权与灰色关联分析相结合的模型也能够对已实施的湿地补水项目的效果进行科学的评价。

Comprehensive benefit assessment of wetland replenishment project based on entropy method and grey correlation analysis

To assess the benefits of wetland replenishment project comprehensively, based on the research and analysis of ecological status of wetlands, the paper established the index system of comprehensive benefit evaluation for wetland replenishment project which included three primary indicators and twelve secondary indicators. Furthermore,the paper applied the model combining entropy and grey correlation analysis to the assessment of wetland replenishment project.In order to verify the feasibility of the assessment method, this paper selected three typical wetland replenishment projects,and used expert scoring method to obtain the original data. the results show that the constructed indicator system is reasonable, and the combined model of entropy method and grey correlation analysis can scientifically assess the effects of implemented wetland replenishment project.
