Abstract:

The urban air temperature is gradually rising in all cities in the world. Records of the past years showed that the climate of built-up regions differs significantly from rural regions. One of the most obvious and important modifying effects of urbanization on local climate is the urban heat island (UHI). In order to clarify the spatial distribution of urban thermal field and to evaluate the urban environment quality synthetically, 5 sites including Xidan, the commercial centre of Beijing district; Mudanyuan, the residential areas; Kunming Lake in Summer Palace, the water body; Chaoyang Park, the urban green space; and Wenquan Village, the suburb of Beijing, were investigated from December 2007 to August 2008. The meteorological factors of temperature and humidity of underlying surfaces in these 5 sites were monitored simultaneously in 10 hours period. The results indicate that the temperatures of underlying surfaces in different sampled landscapes were in the order of suburb.
