摘要
通过分析南北极地区文献数据库 ( AAR CD- ROM) ,极地文献数量、极地主要学科文献数量、极地冰川学科及其分支的文献数量在不同时期的发展变化情况 ,得出的主要结论有 :自 1 70 3年有第一篇极地文献到 1 90 0年间 ,极地文献数量不多 ,1 90 0年左右时间的文献量有一个增量 ,从1 957～ 1 958年的国际地球物理年以来 ,南极研究得到很大发展 ,北极研究则是在 1 970年以来有更大的发展 ,这样的发展势头继续保持着 ;极地研究的有大量的极地冰川文献 ,其次是极地海洋、极地地质、极地生物等学科文献 ;南极地区学科侧重点有天文、大气、地质、生物等学科 ,北极地区侧重在海洋、资源、环境等学科 ;南极研究中发展最快的学科有环境科学、信息科学 ,在北极地区 ,环境科学、生物科学、信息科学和医学的发展较为迅速 ;极地冰川学科与其它学科产生交叉研究 ,出现了一些新的分支 ,学科交叉发展和分支现象在极地的其它极地学科领域也普遍存在 ,也是极地学科发展变化的趋势之一。
WT5BZ] Abstracts AAR (Arctic and Antarctic Regions) CD ROM and its retrieval methods are briefly introduced. After analysing the literature quantities of Polar science, Polar key subjects during the different times from 1700 till 1997, we carefully draw the following conclusions. From 1703 till 1890's, the quantity of Polar literature is very small. Around 1900, the quantity went up dramatically, then it kept at a bit low level. After IGY (International Geography Year) of 1957 to 1958, a rapid progress happened in Antarctic research, so did it in Arctic field after 1970's. The trend continues for decades. Literature quantity of Polar glaciology is the largest. Literature quantity of Polar oceanography, Polar geology and Polar biology is also very large. Polar research of astronomy, meteorology, geology and biology is conducted mainly in the Antarctic region. Polar research of oceanography, resource and environment has the priority in the Arctic. Research on Polar environment and information science develops at the fastest speed. Research of Polar glaciology is conducted across other subjects, and some new subjects come out, which can be universally found in other Polar fields. AAR CD ROM and its retrieval methods are briefly evaluated.
