基于BWM-CRITIC-TOPSIS的幸福河湖综合评价模型

在界定幸福河湖概念及内涵的基础上,构建了包括安全河湖、健康河湖、富民河湖、文化河湖4个方面共17项指标的幸福河湖综合评价指标体系。运用最优最劣法(BWM法)确定指标主观权重,运用CRITIC法确定指标客观权重,并通过最小鉴别信息原理得到组合权重。基于TOPSIS法建立幸福河湖综合评价模型,并通过评价浙江省某市2015—2019年幸福河湖建设水平对模型进行了验证。结果表明:BWM-CRITIC-TOPSIS模型可有效评价幸福河湖建设水平,评价结果与实际情况相符；湿地占地比例、水资源开发利用率等指标限制了该市幸福河湖等级的提升。提出了促进人水和谐、合理利用水资源、提高水资源利用效率等建议。

Comprehensive evaluation model for happy rivers and lakes based on BWM-CRITIC-TOPSIS

Based on the definition of the concept and connotation for happy rivers and lakes, a comprehensive evaluation index system of happy rivers and lakes was constructed including 17 indicators in the four aspects of safe rivers and lakes, healthy rivers and lakes, prosperous rivers and lakes, and cultural rivers and lakes. The BWM method and CRITIC method were used to determine the subjective and objective weights of the index, respectively, and the combined weight was obtained through the principle of minimum identification information. A comprehensive evaluation model of happy rivers and lakes was established based on the TOPSIS method to evaluate its construction level in a city of Zhejiang Province from 2015 to 2019. The results show that BWM-CRITIC-TOPSIS model can effectively evaluate the construction level of happy rivers and lakes, and the evaluation results are consistent with the actual situation. Indicators such as wetland land occupation ratio, water resources development and utilization rate restrict the improvement of happy rivers and lakes grade in the city. Suggestions to promote the harmony between human and water, make rational use of water resources, and improve the utilization efficiency of water resources were put forward.
