In order to find out completely the soil-wheat contaiminated by heavy metals in Tianjin sewage farm, we collect samples on the dry land and examinate contents of heavy metals in soil-wheat system. Firstly, the anthor evaluates that soil irrigated by sewage that has been contaminated slightly, the main polluting factors are Cd and Zn, and then the anthor evaluates soil according to different regions, soil types and irrigating water. Secondly, the anthor analyzes content and enrichment ability of heavy metals in different part of wheat, evaluates wheat is contaiminated by Cd widespreadly, only few samples polluted by Zn.Finally the anthor put up correlative analysis about heavy metal contents in the soil-wheat system, as well as plant enrichment coefficient and some physico-chemical properties of soil, and establishes a prognostic model about heavy metal content among wheat spike, soil, soil types, PH, organic matter and salinity with the quantifying theory.The prognostic accuracy of primarily contaminative factors is the best with compound correlative coefficient examining, the model can be founded.With improvement of living level, people need cleaner food.

Therefore it's necessary to contol the concentration of TW80 to use it in the remediation of pyrene contaminated soil by AMF and corn integrated systerm.4. The AMF community and the single species derived from rock oil-contaminated soil all can be combined with corn and promote the remidation of pyrene contaminated soil , the original AMF community has obvious advantages and behave best.The residual pyrene concentration of soil in the treatments with the mixed AMF community M4 (Glomus intraradices, Glomus mosseae, Glomus etunicatum and Acaulospora tuberculata) and corn integrated systerm got 0.12mg/kg,0.54mg/kg and 3.92mg/kg respectively in 1mg/kg, 10mg/kg and 50 mg/kg pyrene treatments,decreased 32.6%,58.6% and 42.2% respectively than that of the treatment of M1,decreased 28.1%,59.9% and 36.6% than that of M2(G.intradices), decreased 2.7%,55% and 23.5% than that of M3 (G.intradices + G.mossea).5.Large scale reproduce overall of AMF community which coming from rud oil-contaminated soil in the absence of the original conditions will change the quantiy,composition and structure of the AMF population and may has negative impact on it's function in the remedition of soil pyrene contamination.
