The Nanjing city was divided into three types according the building density: Commercial, Hi-dens Res(High intensity residential), Low-dens Res(Low intensity residential). The influence of urban heterogeneity on urban meteorological characteristic in Nanjing was researched by WRF model. The results show that: After considering the effect of the urban heterogeneity, the spatial distribution of temperature, the urban heat island, the relative humidity and the winds exhibit are more complex in the urban region. In the simulations of urban canopy, urban heterogeneity has obvious effects on the heat island and other meteorological characters.The simulated mean heat island intensity, dry island intensity and decrease of wind of city will decrease 0.02℃, 0.2% and 0.11 m·s-1. But the maximum heat island intensity and dry island intensity of city will increase 0.28℃ and 1.51%. In the city of considering heterogeneity, the spaial distribution variances of urban heat island, dry island and decrease of wind will increase 0.06, 2.08 and 0.28.
