The Ganjiang River Basin is situated in southern China,where is rich in water resources. Its water resources are unevenly distributed in time and space,and water demands of various sectors are large during dry season,therefore the problems regarding imbalances in water supply and demand and conflicts among water users in middle and lower reaches are prominent under such circumstance. In order to cope with water resources' shortage in lower reaches of the Ganjiang River in potential condition of less rainfall and low water,water regulation during dry season is simulated,and water shortage and its causes are analyzed. Based on the competitive relationship among water users,an optimized water regulation model is established on the basis of competition between upper and lower areas. The model's effectiveness is also analyzed and discussed,including enhanced water resources utilization and more coordinated upstream and downstream equity in water use.
