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.
