中国土壤重金属污染修复研究的文献计量分析

Biliometric Analysis of Soil Heavy Metal Pollution Restoration in China

以中国知网《中国期刊全文数据库》为检索对象,采用文献计量学方法,从年度载文量与期刊分布、主要产出机构与核心作者群、基金项目、下载量与被引频次、研究热点、高发文量期刊等方面对2005年至2014年土壤重金属污染修复研究文献进行统计分析。结果表明:2005年至2014年10年间发表的相关文献数量及发文刊数逐年增加,而下载量整个10年间呈先升后降趋势,被引频次呈先降后升再降趋势。发文数量最多的两种期刊是《生态环境学报》和《环境科学与技术》,发文数量均为6篇。土壤重金属污染修复研究目前的热点是土壤重金属污染危害及污染修复技术研究。

To better understand the status of soil heavy metal pollution restoration in China, a biliometric analysis was carried out based on literature in Chinese periodical full text database during 2005-2014. All evaluation indices included annual published article amount and journal distribution, main organization and core author group, fund program, download amount, citation frequency, research hotspot, journal with high amount of published articles and so on. The results indicated that during the ten years from 2005 to 2014, the amount of related literatures and journals increased with years, while the download amount increased first and then decreased, while citation frequency decreased first and then increased. The two journals of Ecology and Environmental Sciences and Environmental Science ＆ Technology published the highest amount of related articles, which were six each. The research hotspot of soil heavy metal pollution restoration was soil heavy metal pollution hazard and pollution restoration technology study.
