土壤发生学

中国油茶林地土壤类型的划分，为油茶林地选择及土壤管理提供重要的科学依据。本文应用土壤发生学分类方法，建立了土类、亚类、土属、类型四级分类系统。

A classification with four categories , i.e. , soil group , soil subgroup , soil genus , and soil type , was established , using the theory of pedogenesis .

根据土壤发生学原则，得出土壤性质与风化成土年龄两者间的统计方程。

The statistical equations between soil properties and ages have been determined according to pedological principles .

此外，对土壤发生学分类与诊断学分类之间的参比关系以及土壤分类的定量指标等问题作了初步探讨。

In addition , opinions on relations between the genetic classification and diagnostic classifications were expressed and some quantitative indexes of soil classification were discussed .

制图单元内大部分土壤发生学性质和肥力性质的空间变异性可用坡度和海拔高度的变化来解释。

Most of the space variance about the soil genesis and fertility properties can be explained by the change of elevation and slope in map unit .

在揭示土壤发生学特性及自然、人为影响因素的基础上，构建砂质潮土障碍因素的诊断标准。

The diagnostic standard of barriers in sandy moise soil was established , based on revealing soil genesis and the influence factors including natural and man-made .

由于研究区域范围小（7500m~2）、气候和母质均一，因此土壤发生学和肥力因素的空间变异主要是由地形因素引起的。

Because the area of the research region is very small ( 7500m ~ 2 ), the influence of climate and parent materials is very small , we can conclude that the space variance is mostly influenced by terrain .

结果：高产丹参和低产丹参的药材产量差异极显著（P<0.001），高产型土壤的发生学特征高于低产型土壤。

Result : There was a sharp contrast between the production of high yield and low yield drugs ( P < 0.001 ) . The characteristic value of the high yield soil embryology was much higher than that of the low yield soil .

研究表明，其A层因渍水耕作和施肥，使铁活化度大幅度增高，以土壤剖面发生学论证了土层对称性破缺的耗散结构。

The results indicate that the degree of iron activation are greatly increased in the A horizon of the soil due to water tillage and manuring , therefore the dissipative structure of system 's symmetry breaking are proved on the point of soil profile development .

从20世纪70年代末至今，我国土壤分类经历了由土壤发生学分类向土壤系统分类的重大转变，对北方红色土壤的分类也进行了多次修订。

From the end of 1970 's until now , soil classification had taken place the important transformation which were changed from Soil Genetic Classification to Soil Taxonomy in China .

以土壤的诊断层和诊断特性为依据，以土壤发生学作指导，阐述了我国砂质新成土的系统分类。

Based on the diagnostic horizons and diagnostic characteristics , with soil genetic theory as guide , the taxonomic classification of sandic entisols in China was discussed in this paper .

土壤系统分类与地理发生分类的分类结果是基本吻合的，分布界线也大体一致，说明系统分类是以土壤发生学理论为基础的，两种分类体系有密切联系。

The result of Soil Taxonomy consist fundamentally with that of the genetic classification and the boundaries roughly identify with each other , indicating the taxonomic classification is based on the genesis theory and the two classification system are touched tightly .
