This paper inquired into the behaviors and property of ecological process of heavy metals in soil, the adsorption property of different heavy metals elements are different in the surface of soil colloid, the type of interaction are different for different heavy metals, it directly effects migration and accumulation of heavy metals in soil. The seed bourgeon,seedling growth,crop yield and heavy metals contents were influenced by contaminated soil. Meanwhile enzymology evaluation of contaminated soil by heavy metals were discussed. The property of bioremediation technology were discussed in contaminated soil by heavy metals. The developed trend of pollution ecological process for heavy metals will be discussed in the future.
