STATUS AND TRENDS ANALYSIS ON REMEDIATION OF POLLUTED SOIL IN CHINA BASED ON LITERATURE MOTROLOGY

The papers on remediation of contaminated soil in China recorded in the Chinese Journal Full-Text Database Ｒetrieval ( CNKI) ，Wanfang Data，and Chongqing metrics were statistically analyzed to find out the development status and trend of the soil remediation in China． The result demonstrated that the amounts of papers on soil remediation were increased rapidly from 2000 to 2011，indicating that mach attention had been paid to the remediation of contaminated soil in China since 2000． There were 6 012 authors with 129 core authors and 1 067 research institutes involved． There were 3 institutions that published 100 and over papers． Chinese Academy of Sciences ranked No． 1 in the quantity of published papers． The top 3 most cited articles were published in Chinese Journal of Soil Science and Chinese Science Bulletin． The published paper number and impact factor of Journal of Agro-Environment Science ( Agro-environmental protection) ranked at the fist place， followed by Journal of Anhui Agricultural Sciences，who published 89 in total． Keywords analysis demonstrated that the heavy metal pollution，organic pollution，pesticide pollution were the main type of soil pollution． In terms of soil remediation methods，much more attention was paid to phytoremediation，microbial remediation，and electrokinetic remediation than chemical remediation，physical repair，and leaching repair． The researches on in situ remediation were more than ectopic repair．
