【Abstract】 The tendencies of water demand and supply are analyzed with the case study of Kaifeng Prefecture,one of the water shortage regions in northern China.Different models for water uses of different water users and water inflows are established according to the characteristics of water utilization of different sectors and hydrological tendencies.The water demand and supply for the whole prefecture at different years are forecasted through the models simulation,and the water balances between water supply and demand are analyzed for different years at different planning levels.Thus,it is revealed that it is necessary to save water in the whole(prefecture.)更多还原
