摘　　要：文章以乌鲁木齐建成区为研究区域,使用GIS空间分析方法,对乌鲁木齐城市用地的空间转换过程进行了定量与定位分析,得出以下主要结论:①城市用地发展仍以外延式扩张为主;②城北主要以非城市土地转入城市用地为主,而南部城市中心区的内部用地转换较为明显,并且近期有逐渐加强的趋势;③城市内部用地转换表现出一定的空间分异规律;④地租等市场因素促使城市用地不断向经济效率更高的格局转换,而政府则通过城市规划与土地政策来协调土地转换过程中出现的社会与经济问题。As an oasis metropolis in arid region, Urumqi city, located at Xinjiang, China, is developing rapidly in a fragile oasis ecosystem. With the expansion of Urumqi built-up area, the conversion from non-building land to urban land and the conversion between existing urban land are remarkably. In some degree, urban land conversion can reflect whether the urban develops in a reasonable way. Therefore, this paper selects Urumqi as study area to study on the urban land conversion. Based on the land use map＇s in 1984 and 2002 year, using the spatial analysis method of GIS, the process of main types of urban land spatial conversion is analyzed quantitatively, the characteristics of urban land conversion are summed up and the mechanisms are explained in detail. After analyzing, we get some concludes as follows： （1） the scale and velocity of land conversion from non-building land to urban land is great evidently, and the urban land expansion is more dominant than the conversion of existing urban land; （2） the land conversion from non-building land to urban land is more remarkable in the northern part of city, while the land conversion between existing urban land mainly happened in the southern center of city. But the conversion process of existing urban land is becoming more and more significant; （3） The expansion and conversion of main types of land including Public Facilities land, Residential land and Industrial land has resulted in spatial distribution characteristic respectively; （4） Market mechanism including land price and land interaction plays the basic role to make the urban land utility more effective. Government mechanism including urban planning and government policy harmonize the conflict between economy, society and ecology in the process of urban land use.
