| Abstract: |
| In recent years，biochar has been well known as a new kind of environmental functional material
in controlling the agricultural nonpoint source pollution，improving the weather conditions and soil quality because
of its large surface area，high porosity，and multi surface active groups and so on. It has become a research front of
environmental science research filed. In this paper，we briefly introduced the structure and basic characteristics of
biochar，and reviewed the transport and retention mechanisms of biochar with adsorbed contaminants in the soil porous
media at home and abroad，with an analysis of the factors that influence the biochar migration. Finally，we summarized
the researches on the biochar migration in soil system，to provide some ideas for the application and popularization of
biochar in the future. |
