基于CSCD的盐生植物研究文献计量评价

Bibliometric Evaluation of Scientific Papers on Halophytes Based on CSCD

以中国科学引文数据库(CSCD,477篇)为主线,以维普、万方和CNKI数据库(3329篇)为基础数据,采用文献计量分析的方法,对盐生植物研究文献进行统计分析,分别从文献的年代、机构、作者、来源期刊、学科类别、高被引论文和文献的关键词这7个方面,对盐生植物研究文献的分布规律和研究现状进行总体回顾与评价。全面概括、总结和分析该研究领域研究热点、区域、内容、技术和方法,优秀人才、领先机构和主要团队,揭示中国盐生植物研究的进展情况。结果表明:1956年有盐生植物论文发表,2007年文献总量340篇为最高记录;在CSCD,1991年有盐生植物论文发表,至2011年62篇为最高,均呈逐年上升趋势。中国在盐生植物研究方面已经形成了引领该研究方向的4个主要科研团队,分别是山东师范大学、中国科学院新疆生态与地理研究所、中国农业大学和南京大学。盐生植物的研究呈现明显的地域相关性,热点地区包括新疆、山东、北京、南京、东北、内蒙古、宁夏、兰州等地。盐生植物研究热点是:耐盐性(耐盐机制)、盐胁迫、盐碱地、基因克隆、土壤盐分、植物生长、开发利用、渗透调节、生理指标、种子萌发、脯氨酸、基因工程(基因表达)和植物群落等。

An evaluation of scientific papers on halophytes was conducted on 447 articles indexed by the Chinese Science Citation Database （CSCD） and 3 329 articles indexed by the VIP, WANFANG and CNKI. Articles were re- viewed and evaluated according to year produced, research institution, authors, source journal, subject category, number of citations, and keywords based on bibliometrics. Research focus, regions, content, technology, method, talents, main scientific research institution and teams were summarized and analyzed, and research progress of halo- phytes was described. Our results indicate that starting from 1956, most articles were published in 2007 （340 arti- cles）. However, according to CSCD （starting from 1991 ） most articles were published in 2011. Overall, the num- ber of articles published increased year by year. Four main research teams focus on halophytes in China These are located in Shandong Normal University, Xinjiang Institute of Ecology and Geography of Chinese Academy of Sci- ences, China Agricultural University and Nanjing University. Active regions of China for halophyte research include Xinjiang, Shandong, Beijing, Nanjing, the northeast, Inner Mongolia, Ningxia and Lanzhou. Research focuses on salt tolerance and its mechanism, salt stress, saline-alkali soils, gene cloning, soil salinity, plant growth, resource development and utilization, osmotic adjustment, physiological index, seed germination, proline, genetic engineering （ genetic expression） and phytocoenosium.
