Abstract:

Understanding the dynamic regular patterns of development of industry water use systems for different regions and the correlated relationships among them is the key step to realize watersaving society construction and sustainable utilization of water resource.Currently, the twosection linear models were usually employed to analyze the coordination of regional industry water use systems. However,it may not fit for describing the nonlinear structure of the regional industry water use systems. Hence,a grey synergistic model,which is well adaptive to nonlinear characteristic of the industry water use system,was established based on the theory of grey.The model was applied to the industry water use system in Shanghai from 1997 to 2005.The results showed that coordination degree of industry water use system of shanghai is basically favorable.But there still exists some space for promotion of water use system in Shanghai area, especially for the agriculture subsystem to which more attention should be paid to when planning the industry water use in the future. 〖
