陕西省水资源空间均衡量化评估分析

Quantitative Evaluation and Analysis of the Spatial Equilibrium of Water Resources in Shaanxi Province

摘要:

本研究基于生产、生活和生态三个维度,结合干旱影响,建立了全面的水资源空间均衡评价指标体系,并采用一般剥夺性指数(GDI)对陕西省的水资源空间均衡(WRSE)进行评估。研究结果显示:2012-2022年陕西省 WRSE 均值整体呈现空间不均衡、分布呈南高北低格局;水网建设可使 2035 年陕西省 WRSE 同比增长8.95%,空间均衡显著改善。通过评估,可确定各地级市水资源的不平衡和矛盾,为水网建设规划的顺利实施提供科学依据,对提升陕西省水资源空间均衡具有重要指导意义。

Abstract:

Based on three dimensions of production, living, and ecology, and combined with the impact of drought, this study established a comprehensive evaluation index system for the spatial equilibrium of water resources. The General Deprivation Index (GDI) was adopted to evaluate the Water Resources Spatial Equilibrium (WRSE) in Shaanxi Province. The research results show that from 2012 to 2022, the average value of WRSE in Shaanxi as a whole presents a pattern of spatial imbalance, with a higher value in the south and a lower in the north. The construction of the water grid can make the WRSE increase by 8.95% year-on-year in 2035, and the spatial equilibrium is significantly improved. Through the evaluation, the imbalance and contradictions of water resources in each municipality-level city can be determined, providing a scientific basis for the smooth implementation of the water grid construction plan, which has important guiding significance for improving the spatial equilibrium of water resources in Shaanxi Province.
