Optimization of Water Resource Allocation in Yulin City Based on GW AS Model
Water resources play a crucial role in the socio-economic development of a region.However,the uneven distribution of water resources across China leads to increasingly prominent supply and demand contradictions in many water-scarce areas.Taking Yulin City,Shaanxi Province as the research object and using 2020 as the base year,this study predicts the water demand and available water supply for Yulin City in 2030 using the quota method.The GWAS model is then employed to conduct water resource optimization studies under three scenarios of abundant,normal,and scarce water years.The results show that the allocated water volumes for Yulin City in 2030 under abundant,normal,and scarce water years are 1.619 billion m3,1.842 billion m3,and 1.951 billion m3,respectively,with corresponding water shortages of 10.71％,14.34％,and 16.78％.Under the scenarios of abundant,normal,and scarce water years in 2030,the water shortage rates across all sectors show an increasing trend,with agriculture experiencing the most significant changes,having shortage rates of 15.97％,19.86％,and 23.83％,respectively.After optimization,the water supply structure and balance in Yulin City have been significantly improved,providing a reference for future water resource planning in Yulin City and other regions.
