中文摘要：

利用1995年12月30日、2003年1月10日两期Landsat TM/ETM遥感影像反演东莞市陆表温度（LST）,分析东莞市陆表温度的总体情况及时空特征,并通过引入温度植被指数（Temperature-Vegetation Index,TVX）空间方法,研究城市化对陆表温度的影响。结果表明：城市化进程是导致东莞市陆表温度上升的重要原因,这种作用在TVX空间中主要体现在聚类点由高植被覆盖-低温度向低植被覆盖-高温度区域的运动过程。

英文摘要：

In this paper,the influence of urbanization on land surface temperature（LST） was investigated in Dongguan City.Through the temperature retrieval method proposed by former researchers,the LSTs of Dongguan were retrieved from two Landsat TM/ETM images which were taken in 1995 and 2003.Then,the general situation and spatio-temporal characteristics of LSTs of Dongguan were discussed,the temperature-vegetation index（TVX） space was also introduced to investigate the influence of urbanization over LST.The result indicated that urbanization was an important reason for the LST increase of Dongguan,which was confirmed by the trajectory from the dense vegetation-low temperature condition to the sparse vegetation-high temperature condition in TVX space.
