Abstract: Water environmental improvement depends not only on the combination of water pollution prevention and water resources exploitation, but also on the connection of water pollution control with economic development. Thus it is necessary to solve the water pollution problems radically. Guided by the sustainable development idea, focused on the improvement and protection of water environment and regarded the coordinated development of water environment and economy as a target, the paper puts forward the basic thought of model design, which means comprehensive study of economy, environment and resources must be carried out alongside the study of the coordination of water environment and economy, and the economic system should be taken as a fundamental starting point to study how to control pollution to the optimulevel so as to gain suitable economic structure and developing speed. According to above analysis and based upon the improved Input-Output model of environment-economy-resources-pollution control, the regional multiple-objective optimization model of water environment-economic system is established using quantitative method of systematic analysis, which includes production structure optimization model and industrial structure optimization model. The water environmental protection of Guanzhong region in Shaanxi Province was analyzed with water resources renewable capacity of Yellow River basin. The application of the multiple-objective optimization model is discussed with Guanzhong region in Shaanxi province as an example. The prediction results obtained by using the environment-economy input-output model indicated that if the economy develops at the planned speed, without involvement of the economic structural adjustment, the situation of water environmental pollution will not be improved, and the trends will be worsened, even if the treatment is strengthened. According to the predicted index of economic structure and development, water resources utilization, water environment (discharge of waste water and waste material), investment of water treatment, the economic structure optimization model of water environment-economy was applied to the following items: firstly, the production structure of Guanzhong region in 2010 was optimized at the grade one, and 4 sets of alternative schemes and 1 recommending scheme were given; secondly the industrial structure of Guanzhong region in 2010 was also optimized at the grade two, and 4 sets of alternaial schemes at different investment levels and 1 recommending scheme were given. The results showed that under conditions of the recommended production structure and industrial structure, the economic development rate can not only be kept normal to ensure the realization of the economic target, but the target of water environmental pollution control and the protection of water environment (can also be achieved, leading to the coordinated development between water environment and economy. The study indicates that the economic structure optimization model of water environment-economy can better coordinate the relationship between economy and environment, simultaneously providing an operable method for the sustainable development of water environment and economy.
