国际地震研究发展态势文献计量分析

摘要

以ISI Web of Science论文数据库为数据源,采用美国汤姆森科技信息集团开发的专业数据分析工具TDA(Thomson Data Analyzer)对1900年至2010年(数据入库时间至2010年)国际地震研究发展特点及其现状予以分析.结果显示:国际地震研究持续增长,特别是近20年,增速显著；美国在该领域居于引领优势；政府科研机构、国立科研机构和公共研究机构是该领域研究的主导力量；国际地震研究主要集中于地震机理及成因、地震监测、地震影响及效应等方向；中国虽然已经步入地震研究的主要国家行列,但影响十分有限.%Based on literature analysis using TDA (data from ISI Web of Science database), the authors investigated the status and characteristics of seismological research in the world since 1900. The result shows that seismological research has keep growing, especially in the past 20 years; the growing is notable and the USA takes the dominant position in this field. In addition, the research effort mainly comes from government research agencies, national scientific institutions and public research organizations. Furthermore, the international seismological research focuses on such aspects as earthquake mechanism and seismogenesis, earthquake monitoring, and seismic effect. As far as the sum of research papers is concerned, China has become the important contributor to seismological research, but the influence remains limited.
