摘  要：
针对传统水资源承载力评价只根据评价指标数据进行评价的特点,首先构建评价指标体系,然后将通过标准差贡献率法和群决策相对熵集结模型求得的客观权重和主观权重结合起来求组合权重,根据三支决策思想引入预评分,将改进TOPSIS算法的评分和预评分结合起来求解最终评分,并根据三支决策的评级制思想,将水资源承载力分为优、良、差三级,不仅和实际情况更加接近,而且通过直观地展现评价结果便于人们更好地了解水资源承载力的好坏。

摘  要：
In view of the characteristic that the traditional water resource carrying capacity evaluation is only based on the evaluation index data, the evaluation index system is constructed firstly, and then the combination weight is obtained by combining the objective weight and subjective weight obtained by the standard deviation contribution rate method and the relative entropy aggregation model of group decision-making. According to the three decision-making ideas, pre-score is introduced and the improved TOPSIS algorithm and pre-score are combined to solve the final score. Based on the rating system of the three decision-making idea, the water resources carrying capacity is divided into three levels: excellent, good and poor, which is not only closer to the actual situation, but also easier for people to better understand the water resources carrying capacity by visually displaying the evaluation results.
