摘要
根据全球臭氧地面站（Ｄｏｂｓｏｎ站、Ｂｒｅｗｅｒ站、Ｍ８３和Ｍ１２４ａｌ）总量资料、臭氧探空廓线资料和雨云卫星（ＴＯＭＳ、ＳＡＧＥⅠｆｏＳＡＧＥⅡ）臭氧总量和廓线资料，给出南、北半球特别是南极地区平流层臭氧主要特征和变化趋势。结果表明，无论是中、低纬地区还是高纬地区（特别是南极地区的“臭氧洞”）臭氧总工从７０年代开始呈下降趋势，特别是近十几年来有加剧下降之势，这是各国政府和科学家极为关注的环境和气候问题。此外，还对臭氧总量变化趋势的各种解释作了综述。
On the basis of the total ozone and the ozone profile from global ground stations andsatellite data(TOMS,SAGE Ⅰ and SAGEⅡ),this paper gives main characteristics andtrends in the stratospheric ozone over the Northern Hemisphere and the Southern Hemi-sphere especially the Antarctica. The results show that from the 1970’s the trends of thetotal ozone were decreased either over mid-latitude and low-latitude areas or over high-latitude areas,especially in the 10 odd years it has been an apparent downward trend.This trends have caused much attention from the scientists and politicians throughout theworld. Besides,in the paper some interpretations on the trend or the total ozone are re-viewed.
