基于组合模型的水资源利用效率聚类分析

Cluster Analysis of Water Resources Utilization Efficiency Based on A Composite Model

本文构建了水资源利用效率评估指标体系,基于复合模糊物元-CRITIC组合模型确定综合指数,并应用Ward聚类分析法对水资源利用状况进行划分。结果表明,研究区域水资源利用效率水平符合现状,北京用水效率最高,以北京为中心,向四周递减,且地区间差异较明显。研究方法可为水资源利用和管理提供一定科学依据。

This paper constructs an evaluation indicator system for water resources utilization efficiency.Based on the composite fuzzy matter-element-CRITIC combination model,a comprehensive index is determined,and Ward’s cluster analysis method is applied to classify the water resources utilization status.The results indicate that the water resources utilization efficiency level in the research regions is in line with the current situation.Beijing has the highest water efficiency,decreasing gradually towards the surrounding areas,with significant regional differences.The research methodology can provide scientific basis for water resources utilization and management.
