| Abstract (English): |
In order to support economic and social development and high-quality development of water conservancy, it is crucial to scientifically judge the spatial equilibrium state of regional water resources. Therefore, the Lorentz curve matching water resources with population and GDP was constructed, and the population and GDP were weighted. The comprehensive Gini coefficient of each element after matching regional water resources was calculated to judge the spatial equilibrium state. Subtractive set pair potential was used to identify vulnerable regions affecting the spatial equilibrium of regional water resources. A comprehensive evaluation model of spatial equilibrium of regional water resources based on the Gini coefficient and subtractive set pair potential was established and applied to Chongqing. The findings demonstrate that the water resources in Chongqing are generally in an unbalanced spatial state from 2015 to 2022, particularly in the central city, western regions, and eastern new cities of Chongqing. Concurrently, the subtractive set pair potential in these three regions, manifested as partial reverse potential or reverse potential, designates them as vulnerable regions that impact the spatial equilibrium state of water resources in Chongqing. In the future, it is necessary to take control measures to improve the equilibrium state in these regions. The evaluation model can provide a reference for the high-quality development of regional water conservancy and optimal allocation of water resources. [ABSTRACT FROM AUTHOR] |

为支撑经济社会发展和水利高质量发展, 科学判断区域水资源空间均衡状态至关重要。为此, 构建水资源 与人口数量、GDP匹配的洛伦兹曲线, 对人口数量和GDP进行赋权, 根据计算得到的区域水资源匹配各要素的综合 基尼系数判断空间均衡状态, 采用减法集对势识别影响区域水资源空间均衡的弱区域, 建立了基于综合基尼系数 和减法集对势的区域水资源空间均衡综合评价模型。模型应用于重庆市, 结果表明, 2015—2022年重庆市水资源 空间均衡总体处于不均衡状态。中心城区、渝西地区和渝东新城大部分区域常年处于不均衡状态, 且减法集对势 为偏反势或反势, 是影响重庆市水资源空间均衡状态的弱区域, 未来应以这些区域为重点采取调控措施改善均衡 状态。评价模型可为区域水利高质量发展和水资源优化配置提供参考。 [ABSTRACT FROM AUTHOR] |
