The results of tests on salt content and soluble ions of these samples show that: pH value of soil in this area is between 7.82 ~ 8.26, the thickness of salt collection layer is in 0~20cm, 40~60cm,soil salt is on up as a whole, but there is also some eluviation.

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。

The result show that particle numbers of diameter of floccule which are of narrow-dispersed size between 7 500～20 000 nm are more than 82% of the total when the pH is between 8.5 and 10,with concentation of Fe~(3+) around 40 mg/L and areration rate in the range of 0.10 L/min and 0.14 L/min.

Through different years management, the bamboo forest land soil chemistry nature shows different characteristic .Along with management years increase, soil's pH value go down ; The soil's OM, TN and the hydrolyte N all drops; The soil total P and the available K drops at first ,then go up.

4不同经营年限毛竹林地土壤化学性质变化特点：随着经营年限的增加，土壤pH值变化表现为下降趋势；土壤有机质、全氮和水解氮变化总体下降；土壤全磷和速效钾表现为先下降后上升趋势。

It is shown that, in some areas, such as Tarim Basin, Beishan and Qaidam Basin, although the results derived from traditional Airy model and lithospheric isostasy model are close, the lithospheric isostasy model can explain the nature of the mass balance in a more reasonable way.

计算结果表明，在一些地区，如塔里木盆地、北山和柴达木盆地，尽管岩石圈均衡模型和Airy模型得到了一致的海拔值，但岩石圈均衡模型更能体现均衡过程的物理本质；除青藏高原造山带外的多数块体，岩石圈均衡模型的计算结果更接近观测海拔和地表垂直运动状态；总体上，考虑地幔岩石圈热结构影响后，中国大陆各地区的均衡结果普遍优于传统的均衡模型。
