In an attempt to understand the land-atmosphere feed back invoked by urban and rural heterogeneous surface,the parameterized model of surface energy balance is used with both MODIS and AWS (Automatic Weather Station)meteorological data to calculate surface fluxes in this paper.Surface energy fluxes are analyzed in order to explain the detailed energy differences between urban and rural areas.The results show that the model is feasible and effective.The solution is approximately in agreement with the literature data.This,thereby,provides a useful method for researches on urban climate and environment.
