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.

为全面了解天津市污灌区农产品生产地土壤和旱地作物小麦的重金属污染状况，我们于2004～2005年对全市污灌区的土壤和小麦进行了采样，在对该区土壤—小麦系统中六种重金属元素(Cd、Cu、Pb、Zn、Cr和Ni)的含量进行检测的基础上，本文首先分析评价了污灌区农田土壤的环境质量总体已达到了轻度污染水平，主要的污染因子是Cd和Zn，同时对污灌区农田土壤分区县、土壤类型和不同灌水类型进行了评价；然后分析了重金属在小麦不同部位的含量与富集能力，评价了污灌区旱地作物小麦普遍遭受了Cd的污染，只有个别样点遭受了Zn的污染；最后对土壤—小麦系统重金属含量间以及植物富集系数与土壤部分理化性质间进行了相关分析，由于土壤类型是定性变量，本论文以数量化理论建立了小麦穗实中重金属含量与土壤中重金属全量、土壤类型、PH值、有机质和全盐量间的预测模型，经复相关系数检验，污灌区主要的污染因子Cd和Zn的预测精度最高，模型可以成立。

in pearl river delta region,water environmental contamination featured big amount and mixed types and centralization of pollutant discharge with latent combined pollutants,striding boundary pollution,severe municipal pollution,the trend of regional pollution being extended from cities to rural area,infall of salty tide in recent years.as a result,the unwatered complexion was hastened due to bad water quality.the factors of water environmental contamination were analyzed as the natural factors including especial hydrographic net distributed pattern,water body runoff characteristic,water resource distributive regional difference,infall of ocean tide,and so forth; the artificial factors as inconsequence of economic development mode and distribution of industry and cities planning,lagging environmental infrastructure,indifferency of environmental consciousness,dissonance of economic development and environmental protection.

珠江三角洲地区水环境污染特点表现为：污染物排放量大、类型杂且集中，潜在复合污染出现，跨界污染突出，城市污染依然严重，并呈现出从城市向农村蔓延的区域性污染趋势，加上近几年咸潮入侵加剧，使区域水质型缺水的局面更趋紧张。造成这种污染局面的因素：一方面受控于区域内特殊的河网分布格局，水体径流特征、水资源分配的地区性差异以及海潮入侵等自然因素；另一方面也反映了区域经济发展模式，工业布局和城市规划不尽合理，环境基础设施滞后，环境意识淡薄，经济发展与环境保护不协调等人为因素所致。

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.

因此，在植物与AMF联合修复土壤芘污染中使用TW80应该注意控制TW80的浓度。4、从石油污染土壤中扩繁出的AMF混合菌群及其中的单一菌种与玉米联合均能促进土壤芘污染的修复，原始混合菌群具有明显的种群优势，其与玉米联合修复土壤芘污染的效果最佳。1mg/kg、10mg/kg和50mg/kg芘处理土壤中，玉米接种混合菌种M4(Glomus intraradices， Glomus mosseae， Glomus etunicatum和Arcaulospora tuberculata)处理土壤的芘残留浓度分别为0.12mg/kg，0.54mg/kg和3.92mg/kg，分别比接种单一菌种M1处理降低了32.6%，58.6%和42.2%，比接种单一菌种M2(G.intradices)处理降低了28.1%，59.9%和36.6%，比接种复合菌种M3(G.intradices+G.mossea)处理降低了2.7%，55%和23.5%。5、从石油污染土壤中扩繁出的混合AMF菌群在无原始条件下的整体扩繁会改变菌群的组成及其结构，并会对菌群与玉米联合修复土壤芘污染的功能产生不利影响。
