%X The range of upper troposphere and lower stratosphere(UTLS) is about 520 km.The distribution and change of atmospheric constituents in UTLS are crucial in understanding the climate change.In this region,ozone is an effective greenhouse gas,and water vapor,cirrus cloud and aerosol have important radiative forcing on the weather and climate variation by actively adjusting the solar radiation and long-wave radiation.Aircraft emission and lightning in the strong convection clouds producing considerable NO_x take place in UTLS,which greatly impact the structure of atmospheric constituents in UTLS and upper and lower layers.In this paper,the scientific issues and research methods in the study of stratospheretroposphere exchange(STE) are introduced,and some advances in related fields,especially domestic works in recent years,are summarized.Some key issues and prospects are also discussed.Finally,some expected researches are emphasized in the study of UTLS over the Tibetan Plateau,because the STE processes in this region not only have some significant regional features,but also play potentially an important role in the global STE.
