为明确湘东地区紫色岩风化物和河湖沉积物母质发育的6个典型水田土壤在中国土壤系统分类中的归属,对其成土环境条件、土壤剖面理化性质,以及土壤发生学特性进行研究,依据《中国土壤系统分类检索(第三版)》鉴定其诊断层和诊断特性,确定其在中国土壤系统分类中的归属。结果表明,供试的2类母质发育的水田土壤,pH值均随剖面深度的加深而升高,有机质含量随剖面深度的增加而降低,全铁含量表层土壤低于犁底层和水耕氧化还原层。紫色岩风化物发育的土壤较河湖沉积物发育的土壤颜色更红,水耕表层土壤铁的活化度高于下层土壤,晶胶率低于下层土壤,土壤颗粒组成在剖面层次间变化不明显。鉴定出的诊断层主要有...

Six typical paddy field soils, which were developed from either purple rock weathering or river and lake sediments in the East Hunan, were investigated to make its attribution in Chinese Soil Taxonomy clear. The diagnostic horizon and characteristics of 6 paddy field soils were retrieved out and the taxonomic classification were determined according to Chinese Soil Taxonomy （3rd edition） , based on soil forming environment, physical and chemical properties, and genesis characteristics of soil profiles. It was shown that the paddy soil develop...
