Abstract: Dissolved organic matter (DOM) is an important component in soil solution, it have vital function on soil chemical and biological process. In the past twenty years, many researchers studied the function of DOM in soil and have large progress. DOM will have a significant effect on the retardation factor of most heavy metal or the heavy metal had an especially strong affinity for DOM. The strong affinity have an significant effect on activity of soil heavy metal and environments, and many researchers found that the different source and extraction method have different function. This article review the source、structure、ecology function of DOM and its impacts on activity of soil heavy metal. Based on this, introduce some problems that should be solved in future.
