Abstract: During the springtime Antarctic Ozone Hole,the decrease of total column amount of O 3 is mainly due to the decrease of stratospheric O 3 amount. It is very important to study the atmospheric ozone vertical profile in order to study the formation and development of the Antarctic Ozone Hole. This paper chiefly analyzes the changing of the atmospheric ozone vertical distribution during the 1995 Antarctic Ozone Hole,which is measured by a Brewer Ozone Spectrophotometer and inversed by the Umkehr method.We also compare the ozone vertical distribution before,during and after the Antarctic Ozone Hole,and compare our results with the data of other foreign stations. Here we point out that the decrease of atmospheric ozone over Zhongshan Station during the Antarctic Ozone Hole is chiefly in the lower stratospere(14～25km).This shows that the heterogeneous reaction,which happens on the surface of the polar stratospheric cloud,also chiefly happens at the altitude of 14～25km.
