CAS-based water resources optimal allocation model for east route of South-to-North Water Transfer Project

With the development of water resources,the problem of water resources allocation becomes more and more complex.In consideration of the fact,the theory of complex adaptive system(CAS) was applied to optimal allocation of water resources,and a simulation model for optimal allocation of water resources was developed for the east route of South-to-North Water Transfer Project.The simulation result shows that the coordination degree of society-economy-environment development of the east route system and most provinces increases with the volume of water diversion,and that the non-complete-direct-proportion relationship between the society-economy-environment coordination degree and the volume of water diversion of other one or two provinces results from the adaptability of the subsystem when the volume of water diversion is changed.
