The Application And Extensions Of Coordinated Water And Socio-Economic Development Model(CWSE-E)

According to the review of the studies on Coordinated Water and Socio-Economic development, it has become more important and more necessary to analyse water resources management problems by a coupling model with the function of system state description and water resources policy analysis, which is the basic objectives of this paper.To achieve this goal, we intend to carry out a study of the following aspects:In order to overcome the shortcomings on policy simulation of the Coordinated Water and Socio-Economic development model(CWSE), The Enormous Regional Model for Water (TERMW) that can describe the relationships of water resources and socio-economic system is introduced. Based on model coupling technology, the Extensions of Coordinated Water and Socio-Economic development model (CWSE-E) is constructed. The CWSE-E model is the improvement and expansion of the CWSE model and TERM model, including the improving of water source node network diagram and the building the water sub-modules for regional general equilibrium model analysis. The CWSE-E model is can get effective convergence by input-output table, with a fuction of forecasting, simulation, calculation and policy simulation.The paper compiled2009competitive input-output tables of the Huaihe River Basin based on the input-output method. On this basis, according to the requirements of the TERMW model data structure, the database of TERMW can been drawn by process of calculating of the use structure matrix with imported products, breaking up of non-competitive input-output tables, the construction of investment coefficient matrix, the calculating interregional trade matrix, the assessment of industry water consumption and water revenue, the data can provide the data base for the operation of the general equilibrium model of water resources in the region.Through the CWSE-E model and the consistency data set, this paper carry out scenarios analysis of coordinated water and socio-economic development in Huaihe River basin.The main contents include:(1) The combined effects of water-saving measures, pollution control measures and the protection of the ecological environment impact on the Huaihe River Basin;(2) the proposed results of coordinated water and socio-economic development of each programming year in Huaihe River Basin;(3)The assessment of virtual water policy in the Huaihe River Basin impact on Water Resources Utilization and socio-economic development;(4) The assessment of water rights market in the Huaihe River Basin impact on water use and socio-economic development.
