土壤修复技术研究进展

Research Progress of Soil Remediation Technology

土壤修复技术一般包括物理法修复、化学法修复、生物法修复等,基于知网文献搜索计量方法,根据文献检索结果,分析土壤修复研究热度与时间变化.结果发现,土壤修复领域研究中,生物法热度最高,化学法次之,物理法最低;2008—2018年,各种方法文献数量总体上升,且在2016年出现高数量突破;物理法、化学法热度波动性大,生物法研究持续性好;其中植物、微生物修复表现出较高研究热度和较广应用性.

Soil remediation technologies generally include physical remediation,chemical remediation,biological remediation,etc.This paper analyzes the heat and time changes of soil remediation research based on the literature search and measurement method based on CNKI.The results showed that in the field of soil remediation,the biological method had the highest heat,followed by the chemical method,and the physical method had the lowest heat.From 2008 to 2018,the total number of literature on various methods increased,and a high number of breakthroughs occurred in 2016.Physical method,chemical method heat fluctuation,biological method good continuity of research;Among them,plant and microbial repair shows high research interest and wid e application.
