摘　　要：以京津冀都市圈热环境为研究对象，利用MODIS数据获取了2001、2004、2006和2008年的地表温度，通过温度距平图定性分析京津冀都市圈不同时间、不同城市的热岛强度及变化规律；利用景观学知识，参考热力景观空间格局评价体系，选取缀块个数（NP）、蔓延度指数（CONTAG）和香农多样性指数（SHDI）等对北京、天津两市的热环境空间格局进行了定量描述。结果表明，2001～2004年间北京热力景观格局趋于分散（除夏季外），2004年后逐渐呈集聚状态；夏季北京的热力景观格局异于其它季节，2004年的最为集聚，而2008年的较往年破碎，热场极分散；天津市热力景观格局变化趋势不太明显。The relevant governments have attached great importance to the overall coordination and development of the Beijing- Tianjin- Hebei Metropolitan Circle. At the same time, Beijing, Tianjin and Hebei Province, in an ecological environment, have formed a posture of common influence and radiation. Supported by the temperature anomaly map, the authors chose the heat environment, an aspect of the ecological environment, to make an analysis of the urban heat island intensity and its variation regularity at different periods and places, according to the land surface temperatures of Beijing - Tianjin - Hebei Metropolitan Circle in 2001 - 2008 based on MODIS Data. On the basis of the information from landscape studies, the authors also chose NP, CONTAG and SHDI to make a qualitative description of the spatial pattern of the thermal environment of Beijing and Tianjin according to the evaluation system of thermal landscape spatial pattern. Except for summer, the thermal landscape pattern of Beijing was in a dispersion condition from 2001 to 2004, and then tended to become agglomerate ; in 2008, the pattern was in a agglomeration condition. Summer was different from other seasons： the thermal landscape fragmentation was more obvious and the urban thermal field was in dispersion state in 2008. The change of the landscape pattern of Tianjin is not significant.
