In recent years, the research on the coupling between the Earth’s upper atmosphere and the ionosphere has been paid close attention to by many scholars.On the basis of reviewing the progress of several international research fields in this field, the recent research work and contributions of Chinese scholars are introduced emphatically. This paper introduces the new development of high-level atmospheric observation in China, including optical detection such as laser radar, FP interferometer, all-sky airborne imager, MST radar and all-sky meteor radar etc. In the study of the characteristics of high-level atmosphere, The climatology of the upper atmosphere and the research progress of all kinds of atmospheric fluctuations.On the coupling research of the upper atmosphere and the low ionosphere, the research progress and the research progress of the sodium layer and the sodium layer of the sudden sodium layer and the low-heat layer are introduced, E layer and the atmosphere of the planetary wave coupling between the research work.In the upper atmosphere fluctuation process and ionospheric F2 layer coupling research, focusing on the ionospheric four-wave longitude structure and the upper atmosphere non-migrating tidal coupling between the characteristics and mechanism In the research direction of the coupling between the thermal layer and the ionosphere, the effects of the atmospheric wind field and the gravity wave on the ionosphere in the background of the thermal layer are introduced, In the recent years, Chinese scholars have done a great deal of work in the research field of the coupling between the upper atmosphere and the ionosphere, including experimental observation And data analysis, pattern and theoretical research, etc. The research results made by Chinese scholars have made important contributions to the progress and breakthroughs in this area in recent years.
