The results showed that covering the dich slopes with shrub could significantly increase soil shear strength, compactness and moisture content, and the formed vegetation had significant effects on retarding runoff and removing TSS (P.05). Applying live fascines could significantly increase soil shear strength and TSS removal rate (P.05), but its effects on increasing soil compactness and moisture content and retaining runoff were not significant.

结果表明：与对照相比，使用灌丛垫技术修复后的坡岸土壤剪切力、紧实度和土壤湿度显著提高(P.05)，坡岸植被延缓径流和去除悬浮物效果显著(P.05)；使用柴笼技术修复后的坡岸土壤剪切力和悬浮物去除率显著提高(P.05)，但对土壤湿度、紧实度和雨水径流的延滞作用不太明显。

The result indicated the soil catalase and urease activities and the soil lead concentration is extremely remarkable is connected, may express the lead pollution degree; The lead pollution soil after the Digitaria sanguinalis repair, the catalase and urease activities obtains the restoration, is good according to theirs revivification estimate of the situation Digitaria sanguinalis repair effect.

结果表明土壤过氧化氢酶和脲酶活性与土壤铅浓度极显著相关，可表示出土壤受铅污染程度；铅污染土壤经过马唐修复后，过氧化氢酶和脲酶活性均得到恢复，根据它们的活性恢复状况判断出马唐修复效果较好。

It points out that it must use unsaturated soil theory to consider the stabilization of construction established on loess and dilative soil subgrade. It uses single-phase flow theory and neglects the effect of porous air to describe the flow in unsaturated soil. The saturation of water and pore water pressure are taken as state variables, the effective stress and water flow velocity are expressed using these variables.

对于非饱和渗流孔隙水压力-位移耦合分析问题，本文采用单相流理论，忽略孔隙气压力的变化及其对土体变形的影响，以孔隙水饱和度和孔隙水压力作为状态变量，给出了非饱和土的应力状态表达式、渗流特性，建立了非饱和流孔隙水压力-位移耦合分析的有限元程式。

Along with soil ecology recovery of tailing mine dam, the urease activity is higher of rhizosphere soil of Miscanthus floridulus Warb,SP2and Eleocharis tuberosa Roemet Schult, while it is low of rhizosphere soil of SP1and Neyraudia reynaudiana.

在尾矿坝土壤生态恢复过程中，五节芒、SP2、莎草科植物的根际土脲酶活性较高，而植物SP1、类芦根际土的脲酶活性较低。

On the basis of analysis of the movement characteristics of horizontal layered foundation and the relationship between soil parameters and eigenvalues and eigenvectors of the soil system, frequency domainid entification method of the layered foundation parameters is suggested by correcting the deviation between the measured soil data and theoretical calculation results.

在分析水平层状地基运动特征的基础上，通过研究地层系统的特征值和特征向量与地层参数之间的关系，修正测量得到的数据与理论计算结果之间的偏差，建立了层状地基参数的频域识别方法。

Scientific classification of soils is the basis of utilization and exploitation of soil resources. However, Soil Taxology, characterized by quantification, standardization and internationalization, is not popularized by far. So it is necessary to study its relationship with soil genesic classification and its application for agriculture and environment.

土壤的科学分类是土壤资源开发和利用的基础，土壤的系统分类以定量化、标准化和国际化为特点，但其大众化水平有待进一步提高，尚需加强与土壤发生分类的参比研究，并深化其在农业生产应用、土壤环境评价等方面的实践意义。

The results showed, the intention of erosion of rock and soil has two sides: one is that object of erosion is mixture of rock and soil, that is, the micro-change of composition of soil surface is complexer; another is that the means and degree of erosion is different from original geomorphy.

结果表明，岩土侵蚀的内涵为：一是侵蚀的对象是岩土非均匀混合物，也就是说，地表组成物的微变化比较复杂；二是侵蚀的方式、程度与原地貌有明显的不同。

The result of our experiments showed that PAM has little effect on sandy soil. We analyzed that it is because there are little fine glutinosity soil grain in sandy soil.

研究结果初步表明，PAM在砂性土壤中的施用效果不佳，据分析，这是因为砂性土壤中细小粘粒含量较少，施加PAM后，不能形成较多的水稳性土壤团聚体。

The soil under grassed elleyways had higher NH4+,and K,but lower NO3- than the soil under herbicide strip,with exception that the soil in the layer of 0～10 cm under herbicide strip had higher content of K.

施肥增加土壤速效N的含量。土壤NO3-的季节性变化表明5至6月份土壤中NO3-的含量高，而花前和7月份土壤中NO3-含量低。P、K在清耕带10 cm以下土壤的含量低于生草地土壤，但在0～10cm土层中K的含量高于生草地。P的含量不受影响。
