The inter-coupling relationship between urban economic development and the ecological environment refers to the total of interactive, inter-influenced and other non-linear relations between economic and environmental systems in the course of economic development. Taking ürümqi, an oasis city in arid region, as an example, we collected the data of environmental quality & pollutants discharge and information on economic development in the 20 years, analyzed the correlation between the two, con-ducted a fitted regression with quadratic and cubic equations, and acquired 14 mathematic models that could describe the relationship between the environment and economic development. The results show that there exists a coordinated and interactive relationship between the environment and economic development. On the basis of these quantity analyses, conceptional frame model is built to explain the fundamental basis of this environmental coupling in ürümqi city. Both a quantitative analysis of the coupling law and a good command of the internal law between them are useful for making com-prehensive decisions about the environment and economic development and harmonizing the urban sustainable development.
