| 检索了CNKI中国期刊全文数据库中2006-2016年的我国农地重金属相关文献，通过文献计量分析，初步探明了我国农地重金属的研究现状与趋势。结果表明，从2006年开始，我国农地重金属领域的发文量逐步增长，涉及到第一作者2114名，著录发文机构共635家。发文50篇及以上的机构4家，是本领域的主要研究机构，南京农业大学居首位。刊发本领域论文的期刊共569种，其中《农业环境科学学报》发文量超过100篇，位居榜首。被引频次排在前10的论文总被引频次为1443，被引频次最高的3篇论文分别刊登在《农业环境科学学报》《地理学报》《生态环境学报》上。重金属类型主要涉及到Cd、Hg、As、Pb、Cr、Cu和Zn等，其中涉及Cd污染的最多；我国土壤修复方式以植物修复居多，微生物修复和电动修复较少，原位修复较异位修复多；有关风险评价的论文177篇，涉及的重金属中Cd最多，涉及地区中湖南位居首位。近几年在农地重金属领域的研究主题主要集中在调查、污染评价、累积及化学转化。 |
| 英文摘要: |
| In this paper, literatures about heavy metals in China's farmland were collected from 2006 to 2016 with the Chinese Journal Full-text Database(CNKI), and were statistically analyzed to explore the development status and trend of heavy metals in China's farmland. The results demonstrated that the amount of papers on heavy metals in China's farmland rapidly increased from 2006, involving 2114 first-time authors and 635 research institutes. There were four institutions that published more than 50 papers. Nanjing Agricultural University ranked number one in terms of the quantity of published papers. Papers were published a total of 569 kinds journals in this field, of which the Journal of Agro-Environment Science issued more than 100 papers, topping the list. Cited papers in the top 10 were quoted 1443 times. The top three most cited articles were published in the Journal of Agro-Environment Science, Acta Geographica Sinica, and Ecology and Environmental Sciences. Keywords analysis demonstrated that heavy metal types mainly related to Cd, Hg, As, Pb, Cr, Cu, and Zn, of which Cd pollution was most mentioned. In terms of soil remediation methods, much more attention were paid to phytoremediation than to microbial and electrokinetic remediation. There was more research on in situ remediation than on ectopic repair. There were 177 papers on risk assessments, of which Cd is the most involved heavy metal and Hunan is the most involved evaluation area. In recent years, research topics in the field of heavy metals in agricultural land had focused on pollution investigation and evaluation, as well as cumulative conversion. |
