中文摘要	绿洲是干旱区人类主要活动场所.绿洲规模的多少,直接影响绿洲稳定性和区域经济的发展速度.运用定性定量分析相结合方法,利用实地调查,统计资料和且末绿洲研究靶区的1970,1990和2000年3个不同时期的遥感数据进行解译,分类与统计处理,揭示了且末绿洲30多年来的动态变化趋势,并从自然和人为因素探讨绿洲规模动态变化的原冈和驱动力.结果表明:整个绿洲历年以来是扩张的趋势;这种绿洲扩张从绿洲空间规模和人口增长方面明显的表现出来.研究靶区,从1970年到1990年绿洲～交错带～荒漠之间的转变比较突出;绿洲面积从2.46%增加到19.54%,交错带面积从22.19%减少到6.1:5%.水域和沙漠的变化不太大.从1990年到2000年绿洲面积从19.54%减少到7.02%,交错带面积从6.15%增加到12.94%,水域面积缩小,沙漠面积扩大.研究靶区所出现的这种巨变充分的说明,这里人类活动和自然条件因素对周边生态环境的响应程度.
英文摘要	Oasis is the major area of human activities in arid and semi-arid areas. The size of oasis has a direct impact on the oasis stability and the so-economic development in this area. This research revealed the trend of dynamical change of Qerchen oasis and explored the natural and man-made driving forces of the extention of oa-sis scale during the last 30 years by appling both quantitative and qualitative analysis, on-site investigation and using statistical data and remote sensing data of three time period respectly in the year of 1970, 1990 and 2000, The results showed that the scale of Qerchen oasis had an extending trend throughout the years, and it could be seen clearly from the extention of oasis space and expantion of population. The target area had an obvious shifting change between oasis ～ ecotone ～ desert, oasis scale had increased from 2.46% to 19.54% while the area of e-cotone decreased from 22.19% to 6.15% from 1970 to 1990, but the changes in the desert and the water area were small. During 1990 and 2000 the oasis scale had decreased from 1,9.54% to 7.02%, while the ecotone ar-ea increased from 6.15% to 12.94%, at the same time period water area had decreased and the desert area in-creased obviously. Such a drastic change in research area indicated clearly the strength of human activitis and natural factors to their surroundings.
