N2 - Based on analysis of the relation between various underlying surfaces intercepted from the different-radius circular buffer zones (the radius is respectively 1, 2, 3km, with 11 Shanghai meteorological stations as their center) and their corresponding air temperatures (four times per day, 2 a.m., 8 a.m., 2 p.m., and 8 p.m. (LST)). It is found that a positive correlation between urban land and UHI, and a strong negative correlation between vegetation and UHI. Urban land and vegetation within the range of 1 km around the station affected the observed air temperature from the station. The cooling effect of vegetation within the range of 2 km could not be ignored, whereas that within 3 km was not obvious. The effect of land use on air temperature was most remarkable at 8 p.m., followed by 2 a.m. The effect was not obvious at 8 a.m., and weak effect was observed at 2 p.m. At last, it is mainly discussed the possible reasons for how the correlation between different underlying surfaces and UHI can be formed.
