Research on Balanced Allocation of Water Resources in County
Taking Miyi County as a study case,according to the characteristics of the strictest red line control of water resources and the natural-social water circulation system in a typical county,the minimum overall water shortage rate and regional spatial equilibrium were adopted as the objective function,total quantity control,water supply capacity and different quality water supply are the constraint conditions,and a non-dominant genetic algorithm with improved time-space two-layer elite strategy was ad-opted.The general water resources dispatching and allocation(GWAS)model of regional independent water supply and reservoir group dispatching was constructed.And through parameter calibration and verification,it is concluded that the correlation coeffi-cient R is 0.85 and the efficiency coefficient of Nash is 0.73,and the simulation accuracy of regional hydrology module is good.The scheme simulation shows that,no matter it is the base year or the planning year,compared with the independent water sup-ply of reservoir divisions,the reservoir-group joint regulation scheme considering the equilibrium coefficient has more advantages,and the difference of comprehensive water shortage rate of regional water supply is greater,but in the joint regulation of reservoir groups,the water shortage rate of villages and towns is greatly reduced,and the difference of water shortage is even smaller.The fairness of water resource allocation in the reservoir-group joint regulation scheme is better,and the degree of satisfaction of wa-ter allocation and allocation among each unit in space is high,which can basically achieve the balance of regional water re-sources supply and demand under dynamic changes.
