摘　　要：为了研究贵阳市热环境的发展和变化,采用贵阳市1995年、2001年和2007年TM/ETM+遥感影像,进行亮度温度反演和土地利用分类,分析热力场变化与下垫面变化的关系及12年来贵阳市热力场的变化情况。结果表明:12年来,随着城市的扩展和工业的发展,高温区分布急剧扩大,低温区逐步缩小,原本呈零散分布的低温点则大部分消失。In order to research the development and change of thermal environment in Guiyang,using the Landsat ETM＋ and TM images which were obtained in 1995,2001 and 2007,the surface brightness temperature was computed and the land use was classified,and the relationship between urban heat island distribution and the different underlying types were analyzed,and the urban heat island distribution in Guiyang city in the last 12 years was analyzed as well.The result showed that with the development of city and industry,the high temperature region in Guiyang city expanded and the low one gradually reduced in the last 12 years,most scattered low temperature points even disappeared.
