中文摘要	以于田-且末绿洲1970年(MSS)、1990年(TM)、2005年(ETM)遥感影像和20世纪50年代地形图为主要数据源,在ENVI软件平台支持下,对研究区进行剪切、配准、解译、分类处理,得出分类图和基础空间信息;在此基础上,对比分析了两个绿洲30a以来绿洲面积、耕地变化和经济发展等因素影响下的动态变化与扩张特征。结果表明:30a以来,且末绿洲沿车尔臣河往外缘扩张,扩张特征主要是"跳跃式"模式;于田绿洲沿克里雅河往外缘扩张,其扩张特征主要是"摊饼式"模式。耕地变化上,两个绿洲历年耕地空间变化特征基本相同,两者变化趋势为增长-减少-增长的波动状态。于田-且末绿洲第一产业所占比重基本相似,二、三产业的增长幅度与速度且末绿洲快于于田绿洲。分析可知,绿洲面积、耕地变化和经济的发展都推进绿洲的扩张,但绿洲扩张的同时出现绿洲外部的荒漠化和内部的盐碱化问题,因此为了防止绿洲综合功能的退化,对绿洲进行动态监测势在必行。
英文摘要	According to the remote sensing images of 1970(MSS),1990(TM),2005(ETM) and 1950s topographic map of Keriya-Qerchen oasis as the main data sources,and based on ENVI software platform support,the classification maps and basic spacial information of study area were obtained throng cut,registration,interpretation,and classification processing of images.On this basis above,cultivated land change and oasis area and economic development of two oasis over the past 30 years under the influence of factors such as the characteristics of the dynamic change and expansion were analyzed.The results show that: the rim expansion,expansion characteristics along Qerchen of Keriya-Qerchen oasis are mainly jumps mode over the past 30 years.In Keriya oasis,river along the Keriya outer expansion,main feature of its expansion is booth bread type mode.Farmland change and the spacial change features of cultivated land oases are almost same,which are characterized as the trend of fluctuation regime of growth-decrease-growth state.In Keriya-Qerchen oasis,the proportion of primary industry is similar,increment and development speed of second and third industry in Keriya oasis are faster than those in Qerchen oasis.Analysis shows that oasis area,farmland change and economic development are promoting the expansion of oasis,but expansion of oasis caused the external desertification of oasis and internal salinization problem within oasis imultaneously,therefore,in order to prevent the degradation of comprehensive functions,the dynamic monitoring for oasis is imperative.
