中文摘要	以1999年和2009年Landsat TM/ETM+为数据源,塔里木南缘策勒于田地区的三个不同规模的孤立绿洲作为研究对象,基于"植被-不透水层-土壤"地表组成基础,通过归一化线性分解模型计算了植被丰度和不透水层比率分量.研究通过回归分析和区域分析计算了两分量与地表温度之间的相关性和响应关系,对比分析了绿洲尺度对植被丰度,不透水层比率与地表温度之间相关性的影响.结果表明:(1)植被丰度与地表温度在大规模的绿洲下有较显著的负相关关系,但随着绿洲规模的减小,植被丰度与地表温度之间相关性逐步减弱(R2从0.5~0.6降至0.1~0.2);不透水层分量与地表温度在大规模的绿洲下有较弱的正相关关系,而随着绿洲规模的减小,其相关性几近于零(R2从0.18~0.36降为0.002~0.04);(2)随着植被丰度的增加,绿洲区域温度最大值和最小值受影响较小,而温度均值有明显的减弱;随着不透水层分量的增加,区域地表最低温度有明显的上升
英文摘要	This study take landsat TM/ETM in 1999 and 2009 as an original data and three different scales oasis for isolated oasis in Yutian Cele area in southern of Tarim basin as study area. By the normalized linear unmixed model,we calculate vegetation abundance and percent of impervious surface based on vegetation-impervious surface-soil model, analyze the correlation between surface temperature with the vegetation and impervious, examined the relationship between the scales of the oasis and correlation the surface parameter sand land surface temperatures. The results show that the abundance of vegetation and surface temperature has more significant negative correlation with the weak positive correlation between amount of impervious surface and the land surface temperature in some oasis areas. With the increment of the oasis scales, the correlations coefficient between vegetation abundance and LST and the correlations coefficient between impervious surface and surface temperature raise with an obvious trend, the results indicates that with increase of oasis scales, the extend of local climate change, particularly as oasis ’cool island effect’, was increased as the time from 1999 to 2009. Meanwhile,as growing of rural urbanization, the increasing of proportion of impervious surface present the more significant effect to land surface temperature of oasis
