A time-series Analysis of Land Surface Temperature in Macao, China

Macao city located in the Pearl River delta, China, was chosen to study the effect of urban heat island and its time-series analysis of land surface temperature (LST) in spatial expansion. The LST was analyzed by a temperature separation method based on statistical results. In the case of urban area, it was composed by three parts: downtown and old built-up areas with high-density buildings and dwellings, new built-up areas and developing site. The trend of city development was studied that the developing site would become to be new built-up areas and the formerly new built-up areas would become to be the downtown and old built-up areas. These three parts stand for different stages of a city.
