摘要：
To alleviate the prominent contradiction between water resource supply and demand imbalance of water resources in Wu’an City, Hebei Province, based on the demand for refined water resource management, a regional GWAS (general water allocation and simulation) model of Wu’an was constructed, and the optimal allocation of water resources in various townships of Wu’an City under different scenarios in the planning years (2025 and 2030) was carried out. The results show that in 2025 and 2030, the optimized allocation of water in the model can basically meet the water demand of various townships in the city in the normal scenario (P =50%), while in the dry scenario (P =75%), there are varying degrees of water shortages in each town. There is a widespread agricultural water shortage in the whole city. In 2025, the agricultural water shortage rates in the normal and dry scenarios are 6. 45% and 44. 11%, respectively, and which are 5. 05% and 42. 47%, respectively, in 2030. The optimized water supply structure has significantly improved, and the proportion of groundwater supply has decreased in all planning years under normal and dry scenarios. © 2023, Editorial Board of Water Resources Protection.
