【 摘 要 】

Soil heavy metal pollution was serious in our country and the soil quality was not optimistic. The heavy metal pollution in the soil was concealment, accumulation, non-degradability, uneven distribution and regionality, which was difficult to treatment. Based on the sources of heavy metals in the soil, the characteristics of heavy metal pollution and potential hazards, this paper briefly analyzed the physical methods to repair heavy metal pollution in soil. Then it summarized the related researches on the direction of soil heavy metal pollution remediation by chemical method, biological method and joint repair method in recent years, and on this basis, the future research direction of soil heavy metal repair was prospected.
