In order to comprehensively evaluate the water environment health status of Poyang Lake, a quantitative evaluation index system was established from three aspects of water quality, hydrology and aquatic organisms. The comprehensive weighting method combining analytic hierarchy process and coefficient of variation method was used to determine the comprehensive weights of indicators. The TOPSIS method was applied to construct the evaluation model, which determine the score of evaluation objects by combining the weights of indicators. The results show that there are seasonal changes in the water environment health status of Poyang Lake, and the two indicators of hydrology and aquatic organisms in summer are obviously better than other periods, so that water environment health grade is the highest and belongs to grade Ⅰ, with better coordination; The water environment health grade in autumn and winter is the worst and belongs to grade Ⅲ, among which hydrological condition is the main influencing indicator. This study can provide reference for water environment protection and construction of Poyang Lake.

为综合评价鄱阳湖水环境健康状况,从水质、水文、水生生物三方面建立定量评价指标体系。以层次分析法和变异系数法结合的综合赋权法确定指标的综合权重,运用TOPSIS法构建评价模型,结合指标权重确定评价对象得分。结果表明,鄱阳湖水环境健康状态存在季节变化特征,夏季水文、水生生物指标明显优于其他时段,因而水环境健康等级最高,属Ⅰ级,协调性较好;秋冬季水环境健康等级最差,属第Ⅲ级,其中水文条件为主要的影响指标。该研究可为鄱阳湖水环境保护与建设提供参考依据。

为综合评价鄱阳湖水环境健康状况,从水质、水文、水生生物三方面建立定量评价指标体系。以层次分析法和变异系数法结合的综合赋权法确定指标的综合权重,运用TOPSIS法构建评价模型,结合指标权重确定评价对象得分。结果表明,鄱阳湖水环境健康状态存在季节变化特征,夏季水文、水生生物指标明显优于其他时段,因而水环境健康等级最高,属Ⅰ级,协调性较好;秋冬季水环境健康等级最差,属第Ⅲ级,其中水文条件为主要的影响指标。该研究可为鄱阳湖水环境保护与建设提供参考依据。

In order to comprehensively evaluate the water environment health status of Poyang Lake, a quantitative evaluation index system was established from three aspects of water quality, hydrology and aquatic organisms. The comprehensive weighting method combining analytic hierarchy process and coefficient of variation method was used to determine the comprehensive weights of indicators. The TOPSIS method was applied to construct the evaluation model, which determine the score of evaluation objects by combining the weights of indicators. The results show that there are seasonal changes in the water environment health status of Poyang Lake, and the two indicators of hydrology and aquatic organisms in summer are obviously better than other periods, so that water environment health grade is the highest and belongs to grade Ⅰ, with better coordination; The water environment health grade in autumn and winter is the worst and belongs to grade Ⅲ, among which hydrological condition is the main influencing indicator. This study can provide reference for water environment protection and construction of Poyang Lake.
