摘　　要：生物炭作为土壤改良剂和污染物吸附剂能够改良受重金属污染的土壤,因此受到国内外学者的普遍关注。在国内外研究生物炭改良土壤应用的基础上,概述了生物炭可影响土壤的理化性质和土壤污染物的稳定性,以及生物炭在土壤中可改变重金属的迁移转化行为和微生物群落的行为及其潜在作用,这对未来生物炭的大规模推广应用提供了参考,具有重要的现实意义。As a soil conditioner and absorbent,Biochar can improve soil contaminated with heavy metals,so it is a focus of scholars worldwide. This paper is based on the study of biochars＇ application to contaminated soil,and makes an overview of how to influence oil physical and chemical properties and the stability of s soil pollutants.The biochar can also change the migration behavior of heavy metals in soil and the bacteria＇s behavior,which would be a great potential role for future application,and has a important practical significance.
