摘　　要：选择全国重要的加工业及旅游热点城市西安市作为研究对象,借助RS、GIS等空间信息分析工具,采用西安市2000年、2007年、2014年3个时相的遥感数据反演地表温度,对地表温度进行归一化处理,根据城市热岛分布特点,分析了城市化进程中城市热岛的变化特征.研究表明:随着建设用地的扩张,热岛区域面积逐渐增加并由城市中心向外围延伸,而绿岛区分布在秦岭附近的自然景区、山林水体区域,说明绿色植被及水域有明显的降温作用.Xi'an was chosen to analyze the characteristics of urban heat island effect in the urbanization process. With the aid of RS,GIS methods, spatio-temporal distribution characteristics of urban heat effects were analyzed by using the calculation results of theland surface temperature based on the data sources of Landsat in 2000, 2007 and 2014 of Xi'an. The results showed that heat islandarea increased gradually and extended from the city center to the periphery with the expansion of the land for construction. What'smore, green areas are distributed in the natural scenic areas of the Qinling Mountains. It indicated that green vegetation and waterhave obvious cooling effect.
