Environment radon is mainly from rock and soil in geological environment, but the research is not connected with geological environment now. On the basis of physical field, the theoretical distribution model of radon in soil and exchange model of earth—air are set up by using Fick diffusion law and Dacy law, and then the research of environment radon is linked with geological environment. This paper described how the evry parameter of the theoretical model influence the radon concentration in air. The results of research indicat that molecule diffusion of radon is different from it's eddy form. Under the condition of surface radon source, the model experiment is used to study the transportation and distribution of radon in medium. The data of experiment show the relationship between radon and depth can be described by exponent. If the radioelement is well—distributtion, the concentration of radon in different depth or in different point at the same depth change with time, but the accumulated exhalation amount of radon at different point on the surface of model are close in relative long time. The author studied the exchange of radon between mediums and verified the theoretical models too.

环境氡主要来自岩石、土壤，而目前环境氡研究中与地质环境结合很少，为此作者以物理场为基础，运用气体运移的费克扩散定律和达西定律，建立起壤中氡浓度分布与大地—大气间氡交换理论模型，首次在理论上将环境氡与地质环境结合起来；论文中从理论上讨论了模型中各参数对空气中氡浓度的影响，发现空气中氡运移的分子扩散方式和湍流扩散方式存在明显差异；通过面状氡源条件下的氡运移模型实验，研究了介质中氡的运移与分布，实验数据表明氡浓度随深度的变化规律可用指数函数描述，在放射性元素分布均匀的条件下，介质中不同深度和同一深度不同点的氡浓度随时间而变，但介质表面不同点在较长时间内向空气中累计释放的氡的量是相近的；同时研究了不同介质间氡的交换，并验证了所建立的理论模型；运用理论模型预测青岛市城区壤中氡浓度、江西临川一住宅区空气中氡浓度及江西二个测区的区域空气中氡浓度分布，取得了较好的效果。

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.
