摘要： 以1990年和2007年TM/ETM遥感影像为数据源，利用人机交互解译的方法得到研究区2期土地利用现状图；利用GIS空间分析技术，对天山北坡绿洲城镇用地的扩展采用土地扩展集中指数、土地利用动态度和相对变化率等方法进行分析；同时采用主成分法对城镇用地扩展的驱动力进行研究。结果表明：建设用地中的城镇、农村居民点及其他建设用地的变化在增长规模上与其他用地相比很小，但其变化幅度却是最明显的。受南部山地的限制，北部平原区成为农业用地和建设用地扩展的主要方向。随着经济的快速发展，土地利用方式的选择受到经济收益的影响，人口增加是造成这种变化最直接的驱动力。产业结构调整对土地利用变化的影响较为明显。此外，技术进步和各项投入的增加是促进天山北坡绿洲城镇用地变化的直接因素。

Abstract: Based on the TM/ETM images in the years of 1990 and 2007, this paper demonstrated the current land use maps in the northern slope of the Tianshan Mountains, Xinjiang using the mancomputer interactive interpretation. Expansion of land for urban construction and its driving forces in the study area were analyzed using the spatial analysis of GIS. Specifically, the land concentration, land expansion degree, land use intensity and relative change rate were computed using the principal component analysis. The results show that the expansion of land for urban construction, rural residential area construction and other construction purposes was much less than that of other land use types, but the change extent was the most obvious. Separated by the mountains in the south, the plains in the north were the main areas for the expansion of agricultural land and land for construction. With the rapid economic development, land use change was mainly affected by economic factors although population growth was the most direct driving force affecting land use change. The effect of industrial restructuring on land use change was significant. Moreover, the technological advance and the investment increase were the direct factors promoting the change of land for urban construction in the northern slope of the Tianshan Mountains.

Key words: oasis, urban, land use, driving force, northern slope of the Tianshan Mountains
