基于水资源通用配置与模拟模型的邯郸市水资源优化配置

为实现区域水资源的动态调控，立足河北邯郸市水资源本底条件差且管理需求高的现状，利用水资源通用配置与模拟(general water allocation and simulation, GWAS)模型构建了基于自然-社会二元水循环的动态邯郸市水资源配置模型，在选用1980—2016年和2020年相关数据分别对模型水循环模块和配置模块开展参数率定和验证的基础上，对区域2025年和2035年平水年(保证率P=50%)、枯水年(P=75%)的水资源分别进行配置。结果表明：邯郸市2025年平水年和枯水年的配置水量分别为22.43×10⁸ m³和21.53×10⁸ m³,缺水率分别为11.70%和22.13%,缺水口主要在农业；2035年平水年和枯水年的配置水量分别为25.02×10⁸ m³和23.31×10⁸ m³,缺水率分别为4.53%和21.81%,其缺水情况较2025年明显改善；受邯郸市天然水资源匮乏和西高东...

Optimal Allocation of Water Resources in Handan Based on GWAS Model

In order to dynamically allocate the regional water resources in Handan city, Hebei province, this paper constructed the regional General-Water-Allocation-Simulation model based on natural-social dual water cycle, according to the limit quantity and high management demand of water resources. The water cycle module and allocation module of model was calibrated and validated respectively through the related data from 1980 to 2016 and 2020. The allocation of regional water resources in 2025 and 2035 in normal year (P=50%) and dry year (P=75%) was simulated respectively through the General-Water-Allocation-Simulation model. The results show that the volume of water allocation in normal and dry year is 22.43×108m3 and 21.53×108m3 respectively, the water shortage percentage is 11.70% and 22.13% respectively in 2025. The volume of water allocation in normal and dry year is 25.02×108m3 and 23.31×108m3 respectively, the water shortage percentage is 4.53% and 21.81% respectively which is better than before in 2035. The water shortage mainly exists in agriculture in Handan city. In 2025, the volume of agricultural water shortage in normal and dry year is 2.52×108m3 and 7.22×108m3 respectively, and in 2035, it is 0.99×108m3 and 5.96×108m3 respectively. Due to the limit of natural water resources and the lower terrain in east comparing the west, the shortage gap of water resource is mainly in Wu''an city and Qiu county. The groundwater will still be the main water supply source in Handan city in future, but with the construction of ecological civilization and the comprehensive management of groundwater, the proportion supply of groundwater will gradually decline, while the supply of external water diversion and unconventional water resources will increase. It is concluded that the applicability of General-Water-Allocation-Simulation model in allocating water resources, and provides technical support to the dynamical allocation of water resources in Handan city, indicates the practical significance for the dynamic management of regional water resources.
