南极上空“臭氧洞”形成和演变的分析研究

近十年来，南极地区上空“臭氧洞”的出现、演变趋势及其可能产生的生物学效应和气候效应引起世人的普遍关注和担忧。目前在南极“臭氧洞”形成理论方面，人类活动影响学说占有统治地位，但两年前魏鼎提出的“电化学－动力学”理论颇受重视。本根据作在日本南极昭和站（60°00′S，39°35′E）工作期间，收集和观测到南极臭氧数据、极地涡旋以及有关的太阳和射电活动等方面的资料，作了仔细的统计相关分析。结果为魏鼎提出的理论提供了新的直接证据，进一步指出了由太阳活动所导致的带电粒子流准11年周期变化与南极上空特有的大气环流相结合，是南极“臭氧洞”形成的重要原因，但人类活动（释放化学物质，特别是CFCs）所带来的影响也不容忽视。

ANALYSES AND STUDIES ON THE FORMATiONS AND VARIATIONS OF THE ANTARCTIC OZONE HOLE

The Antarctic ozone hole which was discovered in the mid 1980's has attracted the scientists and politicians throughout the world much attention. For the formation of the Antarctic ozone hole, most scientists believe that the man-made chemical materials such as CFCs etc. are main cause. On the other hand the electrochemistry-dynamics theory presented by Wei two years ago has also attracted some attention. In the paper the data of ozone, solar activity and meteorological elements over Antarctica have been used for statistical analyses and studies. Our results present some new evidence to support the Wei theory. The results show that combination of the quasi-11-years period variation of changed particle current caured by solar activity and special atmosphere general circulation over Antactica is important cause of forming Antractic ozone hole. However the influence of the human activities can never be slighted.
