摘　　要：系统介绍了城市地表能量平衡的物理过程及其参数化方案的研究进展.由于城市化等因素的影响,城市地表能量平衡方案中的各个物理量发生变化,进而影响不同尺度的大气环境和城市气候,尤其是微尺度气候.另外,分析和比较了几种城市冠层模型的特点,及其与中尺度大气模式的耦合,提出目前存在的一些问题和未来的发展方向.结论认为,从中尺度大气模式的研究和发展来看,城市冠层模型和中尺度大气模式的耦合可以有效地提高中尺度大气模式的模拟水平,这也有助于中尺度大气模式的精细化模拟研究,从而更好地理解城市地表能量平衡中各个物理量的变化对大气环境和气候变化的影响.Advances in research on physical processes and parameterization schemes for town surface energy balance were introduced systematically in this paper. Due to the effect of urbanization and some other fac-tors, variations of every physical quantity in the scheme of town surface energy balance can affect atmospheric environment and urban climate on the different scales, especially the micro climate. In addition, the different characteristics of several urban canopy models were analyzed and compared, the coupling of urban canopy models with mesoscale atmospheric models were discussed, some problems and the direction for future development have been put forward. In conclusion, with the further research and development of mesoscale atmospheric models, coupling urban canopy models with mesoscale atmospheric models can effectively improve the simulation level, which will also contribute to the refinement of simulation studies on the mesoscale atmospheric models, to better understanding of the changes of various physical quantities of town surface energy balance on the effect of atmospheric environment and climate changes.
