摘　　要：研究利用TM／ETM+数据,在对福州市1989年和2001年两期数据分别进行温度反演并分级基础上,利用景观生态学知识对福州市热岛的时空格局进行了量化对比分析,结果表明:12年间,伴随着福州市城市化进程加快城市热岛范围大幅增加,1989年的城市次高温区、部分中温区沦为2001年高温区和次高温区．另一方面,由于城市绿化及新城区的合理规划布局,城乡之间热岛强度有所减缓．The brightness temperature is extracted equipped with the TM/ETM＋ dataset which received on June 2, 1989 and May 18, 2001 by this study, then the Time-space pattern of thermal landscape is analyzed using knowledge of landscape ecology unifying the GIS technique. Finally the research indicate that; following the urbanized advancement city heat island scope largely increases during 12 years in Fuzhou,inferior high temperature area and part of warm and inferior warm area degenerate into high temperature area and the inferior high temperature area in 2001 ,on the other hand, as a result of the city forestation and reasonable plan layout of newly built city,the temperature contrast between the city and countryside has slowed down.
