基于集对分析的江门市四堡水库健康综合评价

为研究江门市四堡水库生态健康状况,对四堡水库健康问题进行调查,构建了四堡水库健康综合评价体系,该体系包括水文水资源、物理结构、水质、生物和社会服务功能5项一级指标和16项二级指标。基于层次分析法和熵值法得到主客观权重,进行组合赋权确定各项指标权重,使结果更具合理性。利用集对分析法对水库进行健康综合评价,结果表明四堡水库处于健康水平,准则层中水质指标处于亚健康水平,水库存在向不健康趋势发展的风险。

Comprehensive Evaluation of Health of Sibao Reservoir in Jiangmen City Based on Set-pair Analysis Method

In order to study the ecological health of the Sibao Reservoir in Jiangmen city, the health problems of the Sibao Reservoir were investigated, and the comprehensive health assessment system of the Sibao Reservoir was constructed. The system was composed of hydrology and water resources, physical structure, water quality, biology and social service functions with 5 primary indicators and 16secondary indicators. The analytic hierarchy process and the entropy method were used to combine the subjective and objective weights to determine the weight of each index. The set-pair analysis method was used to evaluate the health of the reservoir comprehensively. The results indicate that the Sibao Reservoir was at a healthy level. Water quality indicator in the guidelines layer was at sub-health level, and there was a risk of developing the reservoir to an unhealthy trend.
