    摘要:

    土壤厚度一般包括土体厚度和有效土层厚度,它能直观地表达土壤性质。基于前人对于土壤厚度定义及相关厚度指标划分所做的工作,结合笔者所在课题组长期野外考察经验,从土壤发生学角度明确了土体的概念,并提出针对不同土壤类型和土地利用方式对应的土体厚度和有效土层厚度的具体划分方法。利用新提出的划分标准对近些年国内各省野外采集的16个剖面(包括安徽、湖北、山东、青海、甘肃、内蒙古等省份)进行具体厚度划分,为国内今后有关研究提供参考。

    Abstract:

    Soil thickness generally refers to thickness of a solum or thickness of the effective soil layer, so it can intuitively express soil properties. On the basis of the work the predecessors have done in light of the definition of solum thickness and relevant criteria for partitioning solum thickness, the authors clarify the concept of solum from the perspective of pedogenesis and put forward some concrete soil thickness partitioning methods specific to soils different in soil type and in land use, while taking into account their own long-term field survey experience. Based on the newly proposed criteria for soil thickness partitioning, 16 soil profiles collected recently in the fields in Anhui, Hubei, Shandong, Qinghai, Gansu, Inner Mongolia and some other provinces were used as cases for soil thickness partitioning. The work may serve as reference for future researches on soil thickness in China.
