Simulation Model and Application on Mutual Optimization of Water Utilization Structure and Industrial Structure in Inland River Basins

During the great development of west China,water utilization structure and industrial structure are both irrational in inland river basins.And they do not fit in with each other.Shortage of water resources is serious.However,traditional water resources optimization focused on water resources but neglected industrial structure.It cannot resolve the present problems.Based on the analysis of interaction mechanism between water utilization structure and industrial structure,simulation model on mutual optimization of water utilization structure and industrial structure in inland river basins is constructed.This model takes System Dynamic Model as the major model,and Input-Output Model,Multiple Targets Decision Model,Grey System Model,Multiple Regression Analysis Method as the assistant models.Restricted by the total quantity of water resources,adjustment of industrial structure is taken as the start.By adjustment of industrial structure,water utilization structure for production is optimized,so is water utilization structure.After optimization of water utilization structure,the total quantity of water utilization should not exceed the carrying capacity of water resources.If it does,industrial structure should be adjusted until it does not.Taking the Heihe River Basin(mainstream),which is one of the largest inland river basins in China,as a case,results show that this model can harmonize the relationship between the upper,middle and lower reaches of the whole river basin.It also can realize the sustainable development of the ecology-production-living system and the water utilization structure-industrial structure system.This model supplies a new thought and method for the sustainable utilization of water resources in inland river basins.
