摘要：
With the acceleration of urbanization, the phenomenon of temperature in urban cities is higher than that in suburbs is called Urban Heat Island (UHI), which is put forward by Lake Howard([1]) in 1833. This paper chose split window algorithm to retrieve land surface temperature after comparing with single window algorithm and multi-band algorithm, and improves the split window algorithm of AVHRR so as to be suitable for MODIS image data. In this paper, land surface temperature is retrieved by split window algorithm based on MODIS' images, and the temporal and spatial characteristics of Beijing urban beat island as well as its influencing factors are also analyzed. The result indicates that: Without particular atmosphere parameter, analysis on urban heat island effect based on split window algorithm of Beijing is available. There is a clear urban heat island in summer, and it is quite dose with vegetation index. Besides, the negative correlation relationship between land surface temperature and PM10 is also emphasizely analyzed.
