The trace of the vertical atmospheric transport has important scientific significance for understanding the transport path of chemical substances in the atmosphere and the process of climate change, and predicting the changing trend of the atmospheric environment. The 7Be and 10Be in the atmosphere are rapidly oxidized after they are formed, and reach the surface with the dry/wet deposition. The concentration of 7Be, 10Be and the ratio of 10Be/7Be can be measured to trace the Stratosphere-Troposphere Exchange (STE). In order to fully understand the process and research status of 7Be and 10Be trace atmospheric vertical transmission, this work analyzed how the 7Be and 10Be can trace STE from the distribution law and influence the mechanism of their concentration and ratio. At the same time, it summarized and reviewed the results of related research. The reason why 10Be/7Be is used as a sensitive tracer of STE was analyzed. Compared with 7Be, it can avoid tropospheric dry/wet sedimentation and dilution of different air masses. It can also obviously avoid the influence of latitude changes and solar cycle changes on its own yield. Finally, this work pointed out that when tracing STE by 7Be and 10Be, it is necessary to pay attention to the difference between the northern and southern hemispheres, the changes in regional latitude, and the geographic characteristics of the research site. The long-period and high-precision 7Be and 10Be data in various regions play an important role in the deposition flux, the trace STE, and the establishment and verification of global climate models. The influence of resuspended dust on the concentration of 10Be and the ratio of 10Be/7Be cannot be ignored, and the Al element correction method is a more effective correction method to remove the influence of dust.
