Oasis city ecological environment and socio-economic development is the only way to achieve regional sustainable development. The paper takes the use of Wuwei City in 2000-2010 statistics to simulate the next 10 years the sustainable development of the Urban System, using SD simulation model in system dynamics to comparative analysis three simulation program of complex systems including population, economy, water resources, land resources, environmental pollution and other subsystems, and explore the problems of Urban System sustainable development in Wuwei City in the future. The results showed that: only when the various factors within the system have maintained stable development trend, that steady economic development, population growth steady, steady increase water consumption, water emissions control increases, so that Wuwei City will maintain the situation of the balance between supply and demand of resources and environmental pollution, and improve and achieve ultimately the sustainable development of complex n Oasis city System.
