摘　　要：地球和行星的高层大气作为大气圈与空间环境的过渡区,是大气科学和空间科学的交叉研究领域.高层大气理论模式及其数值模拟可以突破实验观测的限制,又能够比理论分析更为全面细致地重现高层大气的各种物理和化学过程,在高层大气的研究中表现出独特的优势,也一直是国际高层大气研究热点之一.虽然地球高层大气和其他行星高层大气存在差异,但它们之间有着密切的联系,因此大多数的行星高层大气理论模式都是以地球高层大气理论模式为基础开发的.本文聚焦于地球和行星高层大气理论模式,对目前国内外主流的地球和行星高层大气理论模式的发展历史及其性能进行了系统介绍.The upper atmosphere is the main area of human space activities. It is affected by the neutral atmospheric process, the space plasma process and the coupling between the atmosphere and the space environment. The upper atmosphere is an interdisciplinary research field of atmospheric science and space science.Studying the process and characteristics of upper atmosphere and revealing their formation mechanism are the key tasks in space physics and space weather research. Observations always have the limitations of type and spatio-temporal coverage. Therefore, the numerical models play a more important role to reproduce various physical and chemical processes of the upper atmosphere comprehensively. They have exhibited unique advantages and been one of the hot spots in the community.The upper atmosphere cannot be simply regarded as an extension of the middle and lower atmosphere physically. The numerical model of the upper atmosphere must take into account the limitations induced by the characteristics of the upper atmosphere in model design, coordinate system selection and model algorithm. Therefore, the model development of the upper atmosphere has experienced a long time.In the past decades, modeling of the Earth’s upper atmosphere has made great progress. The community has successfully developed several self-consistent numerical models of the upper atmosphere such as TIEGCM, CTIPe, GCITEMIGGCAS, and etc. These models have made great contributions in the research of the Earth’s upper atmosphere.Although the upper atmosphere of the Earth and other planets show obvious differences, the upper atmosphere numerical models of the Earth and other planets closely relate with each other. Most models of other planets were developed on the basis of the Earth’s models. Great progress has been made in the numerical modeling and corresponding research of the planetary upper atmosphere.Due to the lack of understanding of the planetary upper atmosphere at present, comparing with the numerical model of the Earth’s upper at
