摘　　要：为了揭示城市热岛形成机制,基于MODIS资料,结合自动气象站实测的气象资料,利用地表能量参数化方法估算了地表热通量,分析了城乡地表热通量的空间分布及变化特征.结果表明城乡地气热交换差异明显,与相关文献对比证明该方法是可行、有效的.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.
