摘　　要：2011年空前的北极臭氧损耗,引发了人们对臭氧和臭氧洞的新关注。本文回顾了南极臭氧洞的由来及变化;讨论了南极臭氧洞产生的原因以及南北极臭氧变化的差异;指出目前只是在南极春季出现了臭氧洞,北极并没有出现过臭氧洞。在当前大气环境被污染的情况下,极地大气臭氧亏损的程度将更多地随大气环流,特别是极地涡旋中的低温状况而发生变化。人类只有一个地球,为保护大气臭氧层,国际社会做出了巨大的努力,中国也有自己的贡献。The unprecedented depletion of ozone over the Arctic in 2011 attracts the attentions of people to the ozone and ozone hole once more. This study reviews the history of the Antarctic ozone and its change. The reason how the ozone is produced over the Antarctic and the difference of the ozone changes over the Arctic and the Antarctic are discussed. It is pointed out that, currently, the ozone hole appears only in spring over the Antarctic and not over the Arctic. Under the current atmospheric environmental pollution, the change of atmospheric ozone depletion over the polar regions will be more dependent on the atmospheric circulation, especially the low temperature in the polar vortex. For protecting the Earth dwelled by human, the international society has made a great effort, and China also has made some contributions to it.
