    摘要:

    对采自江汉平原区的69个典型土壤剖面,按照《中国土壤系统分类检索(第三版)》进行鉴定、检索和分类,确认了诊断层和诊断特性,明确了其在系统分类中的归属,共划分5个土纲、5个亚纲、8个土类、18个亚类。讨论了江汉平原成土母质、地形及人类活动对土壤属性和土壤空间分布与演化的影响,表明中国土壤系统分类体系能很好的反映母质、地形、人类活动等因素的空间变异与土壤类型分布规律,为进一步完善土壤系统分类研究提供范例。

    Abstract:

    A total of 69 soil profiles typical of the Jianghan Plain were collected, identified and classified in line with the “Keys to Chinese Soil Taxonomy (CST)(3rd ed.)”, and their diagnostic horizons and diagnostic characteristics were determined, and their attributes in the taxonomy defined. They were sorted into 5 Orders, 5 Suborders, 8 Groups and 18 Subgroups. Besides, influences of soil parent material, topography and human activities on attributes, spatial distribution and evolution of the soils were discussed. Results show that the CST system reflects properly relationships of distribution of soil types with spatial variation of its influencing factors, such as parent material, topography and human activities, which has provided some practical examples for further perfecting the soil taxonomy.
