黄土

In order to get more scientific information on the clsssification and use of two kinds of typical paddy soils in Jiangsu Province, we studied four soil profiles from two different regions:the Xiashu loessial uplands and the low lands to the east of Hongze Lake.

为给江苏省两种典型水稻土的分类和利用提供更多的科学依据，我们对两种不同起源土壤的四个剖面进行了研究。一类为下蜀黄土丘陵谷地，另一类为洪泽湖以东的低温地。

This problem study way: study on the theories of composite ground and physical mechanics character of loessial soil, deduce a hypothesis and test it according to rules or regulations, analysis and prove the theory, design, test, application, examination, and summary.

本课题的主要工艺技术路线：研究黄土的物理力学性质及复合地基理论→与规范、规程相结合进行构思、假设和试算→理论推导与证明→设计→试验→实施→检验→总结。

This study was therefore conducted in a small watershed of the loessial gully region to reveal the profile distribution of soil properties as affected by landforms.

论文研究了黄土高原沟壑区小流域地形条件对土壤性质剖面分布的影响，结果表明土壤硝态氮、速效磷、碱性磷酸酶和蔗糖酶为高度变异的土壤性质；pH值和过氧化氢酶为小变异土壤性质。

The purification mechanism to As is not only absorption , and also includes other physical and chemical actions. 5 The main factors influencing loessial soil purification to Cr and As are pH, organic matter, calcium, iron, aluminous compounds and contents of mucilaginous grain etc.

对As的净化机制不只限于吸附作用，还包括沉淀等其他理化作用；⑤影响黄土对Cr、As起净化作用的主要因素有pH、有机质、铁、铝、钙化合物、土壤粘粒含量等。

On the basis of these, the author studies the following problems and draws corresponding conclusions:(1) By demonstrating physichemical and structural character of loessial soil, the results are obtained that it is having great meaning to utilize widely distributive and profound loessial soil resources to purify sewage for protecting groundwater supplying security.

在人类农事活动和水事活动日益增强的情况下，如何利用包括土壤层在内的黄土地层自身的净水作用，保护地下水不受污染，具有重大的理论和实际价值，这是本论文的立项依据。

The ground treatment method for composite ground base with rammed cement soil pile is widely applied in north china in recent years, and there's no former confirmed theory on using this method through seal and extrusion to settle the problems of wet and sinking and bearing capacity for loessial soil.

夯实水泥土桩复合地基是近几年在华北地区应用较多的一种地基处理方法，利用该种方法通过挤密同时解决黄土湿陷性和承载力问题的研究还未见先例。

With increasing of human being's activities on farming and watering, it has great theoretical and practical significance on how to utilizing purification function of loessial soil to protect groundwater from polluting, which is the basis of building item of this paper.

地下水是黄土地区重要的水资源。

Between Cr and As have possibly promotion to absorption amounts in loessial soil.(6) Utilizing infiltration experiment of soil column, the results show that environmental capacity of Cr and As in loessial soil is 95.9kg/ha and 12.6kg/ha.

6在全面阐述土壤环境容量模型的基础上，用土柱淋滤试验方法研究首次得出了黄土类土中铬、砷的土壤环境容量分别为95.9kg／ha和12.6kg／ha。

The results showed that the upper section of the profile contains more coarse fractions and loessic fractions, with the presence of gravels, showing vertical changes in grain size. All of these suggested that the upper section is loessic material deposited by water.

研究结果表明：凤凰山剖面上部含有砾石，粗粒组分含量较高，且垂向变化均较大，分选性较差，但同时颗粒组成仍以风成沉积的两个主要粒级为主，为经流水作用改造的次生黄土。
