摘要
以SCI、ESI(基本科学指标数据库)、GEOREF等数据库为统计分析源,对1993—2003年国际及中国地球科学的发展现状和发展态势从文献计量学的角度进行统计分析,分析了国际地球科学论文产出的主要领域、国家、机构、科学家和期刊,对中国地球科学论文产出的主要领域进行比较分析,并通过论文产出、被引频次、篇均被引频次和国际1%顶尖论文数量对比反映中国的科学影响力。结果表明,国际环境科学和生态学研究论文增长很快,占地球科学相关主题领域论文的比例也比较大,但中国生态学研究论文无论从占国内22个学科论文产出的比例,还是从占全球该领域的比例来说都有较大差距;中国地质科学领域研究重点在地球化学、金属矿产和能源的经济地质学,但在环境地质学领域研究相对较少,而国际上环境地质学研究论文的发展已经大大高于传统的地质学论文。
By using some authoritative databases such as SCI?ESI(Essential Sciences Indicators)?GEOREF, the paper makes a bibliometrical analysis of status and trends of the international earth science studies, including analysis of major research countries, major subjects, major research institutions and major scientists through paper output statistics. Analysis is also made of major research fields and international influence in earth sciences in China by paper number, citations, citation per paper and number of top 1% highly cited papers. papers Results show that, between 1993-2003, the number of international papers in environmental science and ecology are increasing very rapidly and has a heavy proportion, but the proportion in China is on the low side.The number of paper in Environmental geology has a big proportion in the world, but in China it's relatively small. Major research fields in geosciences in China focus on geochemistry, geology of metal deposits and energy resources.
