Hotspot issues of heavy metals in China's farmland based on bibliometrics
摘要
Abstract
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 as-sessments,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.关键词
