为了研究湖南省东部地区紫色土在中国土壤系统分类中的归属,选取6个典型紫色土土种的土壤剖面,在对其成土环境、剖面形态特征及其理化性质研究的基础上,按照中国土壤系统分类检索、土族和土系划分标准,确定了其在中国系统分类中的归属及其土系的划分。结果表明：（1）受局部区域气候条件、植被类型和地形地貌等成土环境的影响,湘东地区所调查的6个典型紫色土土种剖面的发生特性不尽相同,检索出的诊断层包括淡薄表层和雏形层,诊断特性包括湿润土壤水分状况,热性土壤温度状况,准石质接触面,铝质特性,铁质特性,红色砂、页岩、砂砾岩岩性特征和氧化还原特征,分别归属于雏形土和新成土2个土纲,包括了...

To study on the taxonomy attribution of purple soils,six typical soil profiles of purple soils in eastern Hunan were selected,then the characteristics of soil-forming environment,profile morphology and physic-chemical properties were studied,and finally their attributions based on Chinese Soil Taxonomy were determined and their soil families and series were established.The results showed that the genetic characteristics of the 6 profiles were quiet different due to the influences of regional climatic condition,vegetation types and landforms.The...
