【摘要】：根据土壤发生学理论,在土壤景观相似的土壤中(如相同母质、相似气候、相同地形以及相似的植物类型和动物活动),土壤的属性具有相似性;然而由于地理环境中复杂的成土因素的影响,土壤绝无完全相同的土壤个体。在划分土壤地理发生分类基层单元土种和系统分类基层单元土系时,特定土层被用于反映土体构型差异。但特定土层类型多样,目前尚处于模糊状态,随着土系划分研究的深入,有必要对其进行分门别类与归纳整理。本文以河南省典型土系为例,梳理和总结了土系划分时涉及的主要特定土层,从特定土层形成根源上将其分为现代成土环境下土壤发生过程形成的、地质成因或地质时期土壤环境下发育形成的和人类活动产生的三个类型,并提出了基于土系概念的特定土层分类与检索体系,旨在使特定土层的概念更为系统、全面、开放,以便于使用。
[Abstract]:According to the theory of soil genesis, the properties of soil are similar in soils with similar soil landscape (such as the same parent material, similar climate, the same terrain and similar plant types and animal activities). However, due to the influence of complex soil-forming factors in the geographical environment, there are no identical soil individuals. In the division of soil geographical classification unit soil species and systematic classification base unit soil series, the specific soil layer is used to reflect the difference of soil configuration. However, there are many types of specific soil layers, and they are still in a fuzzy state at present. With the deepening of the research on the division of soil systems, it is necessary to classify and summarize them. Taking the typical soil series in Henan Province as an example, this paper combs and summarizes the main specific soil layers involved in the division of soil series, and divides them into the formation process of soil formation in modern soil-forming environment from the origin of the formation of specific soil layers. There are three types of geological origin or soil development in geological period and human activities, and a classification and retrieval system of specific soil layer based on the concept of soil series is put forward in order to make the concept of specific soil layer more systematic, comprehensive and open. For ease of use.
