Selection of covering materials on ground parking lot, as an important urban underlying surface, affects urban ecological environment. The study aimed at providing reference on the heat respect for the selection of ground parking lot's surface material. Based on the observed 12-month data of surface temperature, air temperature and direct solar radiation for four frequently-used surface materials, i.e., asphalt, cement, concrete ground brick and grass brick, the variation characteristics of surface and air temperature and their influencing factors were analyzed, and the analysis of the correlation between surface temperature and meteorological factors was made. Results show that:(1) The covering materials, in order of decreasing temperature, were asphalt, concrete ground brick, cement and grass brick. (2) The surface temperature had positive correlations with air temperature and direct solar radiation, of which air temperature makes more contribution. (3) Linear regression model about meteorological factors was established to provide a better theoretical support for the service of meteorology. The model can be used to calculate real time surface temperature.
