摘要
水资源承载力研究是城市可持续发展研究的重要组成部分。为了提高水资源利用效率,以山东省某城市为例进行实证研究,以可持续发展为目标,从定量的角度分析水资源承载力的现状及影响因素,建立城市水资源承载力的综合评估模型。结果表明,水资源子系统的承载力在2013年达到0.3421,2020年社会子系统水资源承载力为0.0061,水资源承载力波动逐年减小。研究确定了水资源承载力的主要影响因子,可为水资源管理提供决策支持。
The research of water resources carrying capacity is an important part of urban sustainable development.In order to improve the efficiency of water resources utilization,this study took a city in Shandong province as an example to conduct an empirical study.Aiming at sustainable development,analyzes the present situation and influencing factors of water resources carrying capacity from a quantitative point of view,and a comprehensive assessment model of urban water resources carrying capacity was established.The results showed that the carrying capacity of the water resources subsystem reached 0.3421 in 2013,and that of the social subsystem was 0.0061 in 2020,and the fluctuation of the water resources carrying capacity decreased year by year.This study identified the main influencing factors of water resources carrying capacity,which can provide decision support for urban water resources management.
