The soil pH, CEC and organic matter content ranged from 7.7 to 8.6, 11.9 to 28.7 cmolkg^(-1), and 3.0 to 27.9 gkg^(-1), and followed normal distribution, log-normal distribution, and negative binomial distribution, respectively. These three properties were significantly affected by land use type, landform, and soil type.

结果表明：黄土高原小流域土壤pH、CEC和有机质分别介于7.7~8.6、11.9~28.7cmolkg^(-1)和3.0~27.99kg^(-1)，分别服从正态分布、对数正态分布和负二项分布。3种土壤性质随地形、土地利用方式和土壤类型的不同差异很大。

The nonparametric statistic method was also used to systematically analyze the soil physiochemical properties and the environmental risk of birth defects,combined with analysis.

By comparison with theoretical K value to figure out variance and to find out the main soil character parameter. Using MATLAB software, theory of parameter modification is employed to modify parameters in Normal Equation. Eventually, the proper calculating model of K factor the same with the typical slope soil of highway in Hubei Province, is established.

比较理论土壤可蚀性因子K值及实测土壤可蚀性因子K值之间的差异，找出导致该差异的主要土壤性质参数，在此基础上运用MATLAB数学分析软件对诺模方程进行修正，以得到适用于湖北省孝襄高速公路边坡代表性土壤的土壤可蚀性因子K值的计算模型。

The soil character had greater impacts on the non-dominant commnunity, individual density and Enemata than the main community of microorganisms; Actinomyces had greater impacts on Coleoptera and Oligochaeta opisthopora; Fungi had greater impacts on Isopoda and Formicidae.

土壤性质对弱势类群、土壤动物种群密度和土壤线虫影响比土壤微生物的影响大；放线菌对鞘翅目和后孔寡毛目影响较大；真菌对等足目和膜翅目蚁科影响较大。

Invariableness wind velocity is used in experiment to measure soil erosion of different land use and then discover: Wind erosion quantity is close related to type of land use.

利用恒定风蚀风速，对不同用地风蚀量进行测定，发现土壤风蚀量的大小与土地利用类型之间有着密切的关系，而土地利用类型决定了地表植被盖度、土壤表层水分及土壤性质。

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。

Soil CEC and organic matter content were higher in forest-land, grassland and farmland than in orchard land, and soil pH was lower in forestland than in other three land use types. Soil pH, CEC and organic matter content were higher in plateau land and sloping land than in gully bottom and terrace land. Soil CEC and organic matter content were higher in dark loessial soil and rebified soil, while soil pH was higher in yellow loessial soil.

不同土地利用方式下，土壤有机质和CEC以林地、草地和农田较高，果园较低；pH则以林地较低，其他利用方式较高；不同地形条件下，3种土壤性质均呈塬面和坡地大于沟道和梯田的趋势；不同类型土壤中，有机质和CEC以黑沪土和红土较高，pH则以黄绵土较高。
