It is of great scientific significance to study the relationship between urban surface cover and land surface temperature (LST) for improving urban ecological environment. Based on the Landsat TM data, this paper uses the linear spectral hybrid analysis model to extract the impervious surface land information. Combined with the LST and surface heat flux, the spatial-temporal variation characteristics and inter relationships of the impervious surface area (ISA) and the LST are analyzed. The results show that the ISA of Beijing increased rapidly from 1984 to 2014. The medium coverage of ISA decreased, while high coverage increased remarkably. The LST decreased from the city center to the suburbs, and the high temperature area was expanding continuously. There was a significant positive correlation between the LST and ISA, and the rate of the LST rise was the fastest when ISA was at 0.6-0.9. So reducing ISA can alleviate the phenomenon of high temperature area concentration.

Key words: Impervious surface area (ISA), Coverage, Land surface temperature (LST), Spatial-temporal features, Beijing
