选取湖南省中南部丘岗地区11个土壤剖面,研究其土壤成土环境和形成特点。结果表明,该区土壤质地以黏土为主,土壤黏粒淋溶明显,黏化过程较强,各剖面表现出铁游离度高、活化度低的特点,处于中度富铁化过程。根据《中国土壤系统分类检索(第三版)》,鉴定了诊断层和诊断特性,确定了供试土壤剖面在中国土壤系统分类中的归属,其中原发生分类中的红壤(04、22、23号剖面)属普通强育湿润富铁土;红壤(07、13号剖面)属网纹简育湿润富铁土;菜园土(19号剖面)属斑纹肥熟旱耕人为土;紫色土(20号剖面)属酸性紫色正常新成土;粗骨土(21号剖面)属普通湿润正常新成土;石灰土(01号剖面)属普通钙质湿润雏形土;紫色土(16...

This paper deals mainly with soil-forming factors and characteristics of soil in hilly regions of central-south Hunan province through investigating eleven soil profiles. The results showed that the main soil texture was clay, which showed obvious leaching phenomenon and strong viscidity. The soil profiles were characterized by high degree of iron segregation and low activity of iron oxides, which were in the process of moderate iron-accumulation. According to the ＂Chinese Soil Taxonomy Index （the third edition）＂, diagnostic horizons and di...
