In this paper,the oasis cities in Kashgar Prefecture and Kizilsu Kirgiz Autonomous Prefecture are taken as an example,through the factor analysis,spatial attraction interaction model and location quotient methods,urban hierarchy system,the intensity of urban economic ties,economic subordination degree,and structure of city functions were analyzed. The results indicated:(1) The urban hierarchy system takes Kashgar city as the main center,Artux city,Yarkant county and Maralbexi county as the sub-centers; (2) The intensity of economic ties among Kashgar city and each county is much higher than others. The interaction of Kashgar city,Shufu county and Shule county are the strongest,and the economic ties of Yarkant,Kagilik,Poskam counties are relatively close; All cities in the study area are economically subordinate to Kashgar city. (3) Three cities of Kashgar city,Shufu county and Shule county should connect strongly,with Kashgar city as the core. The cities and towns along the Southern Xinjiang Railway and along National Road 315 should be regarded as two strips,and the two city strips along the border,and the city strip along Provincial Road 215 should be treated as three axes. The ring structure strategy of 'core ring,closer ring and radiated ring' was proposed. (4) It was proposed to build Kashgar city group in the north,and Yarkant city group in the south,Maralbexi city group in the southeast,and Taxkorgan border city group with four inner groups’ development strategy.

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.
