Status and trends of rice science based on bibliometrics | 基于文献的国内外水稻研究发展态势分析

中国人. 目的利用文献数据库，客观地分析国内外水稻的发展动态，为国内外水稻科研工作者和决策者提供参考，促进水稻科研工作的可持续发展，保障粮食安全。方法基于Scopus数据库，采用文献计量学方法，对全球及中国、美国、英国、日本和印度发表于1998―2009年的水稻文献的数量和质量进行分析，并分析了此期间水稻文献发文量居世界前20名中国前10名的核心作者、科研机构及文献累计引用篇次居前的文献。结果检索到全球100多个国家在1998―2009年间发表的水稻文献42 307篇，及每篇文献的被引频次，每个国家、机构或作者的H指数。结论全球水稻研究论文的产出量呈逐年上升趋势，水稻论文占全球总发文量的比例也呈上升趋势，尤以中国的水稻发文量增加最为明显。水稻文献的质量在统计的5个国家中，以英美最好，日本略高于世界平均水平，中国和印度低于世界平均水平。日本、中国和美国的高产活跃作者最多；国际水稻研究所、中国的浙江大学、日本的农业生物资源研究所和美国的康奈尔大学等机构的水稻研究论文影响力较大；水稻研究的热点是分子生物学。

Method The published rice articles from China, the United States, the United Kingdom, Japan and India as well as other countries during 1998 and 2009 based on the Scopus database were analyzed. Result A total of 42 307 rice articles were identified from more than 100 countries, meanwhile, the number of cited times for each article and the H indices for each country, affiliations and authors were retrieved. Conclusion The output of rice articles in the world and the rates of rice articles to the total number of world articles increased year by year, especially in China. In the five countries under study, the cited rate and the H indices of the rice articles, as well as the high cited article rates from the United States and the United Kingdom were the highest, those from Japan were higher than the average values of the world, and those from China and India were below the average values of the world. There were more core authors in Japan, China and the United States. The effects of the rice articles from the International Rice Research Institute, Zhejiang University in China, National Institute of Agrobiological Sciences in Japan and Cornell University in USA were stronger. The research hotspot in rice was molecular biology.
