Abstract:

During the process of regional economic and social development, it has become an essential technical issue  to improve the efficiency and benefits of water use via controlling regional water utilization structure under predetermined water supply and ensure the development of economy and society to be matched with gross volume constraint of water. In this paper, we chose several indicators to quantitatively describe the coupling relations between water use and socioeconomic system, refined indicates of the primary, secondary, and tertiary industries, domestic and ecological consumption which are divided in the way of combining national economy sectors and water consumers, and set up the system dynamic model of Jiangsu Province which simulates water utilization structure and industrial structure and considers demand of water use and socioeconomic development. Based on the prediction and analysis of the current development trend of total water use in Jiangsu province, we selected parameters which affect system significantly as the controlling variable, designed five kinds of scene for contrasting, simulated changes in supply and demand of water resources and water utilization structure dynamically, to identify the simulation program of total amount of water constraining and water utilization structure controlling strategy in Jiangsu Province. The findings can help to promote regional economic development pattern and to take the intensive and organic growth path of development
