摘要
为了确定湘东地区板岩红壤在中国土壤系统分类中的归属,选取该地区7个由板岩母质发育的典型红壤土壤剖面,在对其成土环境、剖面形态特征及其理化性质进行系统研究的基础上,按照中国土壤系统分类方案,检索出了诊断层和诊断特性,据此确定了其在中国系统分类中的归属。结果表明,供试土壤剖面的位置分别为:淋溶土、雏形土、富铁土和新成土4个土纲,湿润淋溶土、湿润雏形土、湿润富铁土和正常新成土4个亚纲,酸性湿润淋溶土、铝质湿润淋溶土、铝质湿润雏形土、黏化湿润富铁土和湿润正常新成土5个土类,普通酸性湿润淋溶土、普通铝质湿润淋溶土、普通铝质湿润雏形土、普通黏化湿润富铁土和石质湿润正常新成土5个亚类;按照土族和土系划分标准,建立了黏壤质硅质混合型酸性热性—普通酸性湿润淋溶土等6个土族和高升系等7个土系(43-CS16)。
To study the attribution of the slate red soil in Chinese Soil Taxonomy in eastern Hunan,we selected7typical red soil profile developed from slate in this area,according to the Chinese Soil Taxonomy,we retrieved out the diagnostic and its features,and determined its attribution based on the study on the soil forming environment,the morphological characteristics and the physical and chemical properties.The result shows that the location of the soil profiles are belong to4orders such as argosols,cambosols,ferrosols and primosols;4suborders like udic argosols,udic cambosols,udic ferrosols and orthic primosols;5groups as acidi-udic argosols,ali-udic argosols,aliudic cambosols,alliti-udic ferrosols and usti-orthic primosols;and5subgroups as typic acidi-udic argosols,typic ali-udic argosols,typic ali-udic cambosols,typic alliti-udic ferrosols and lithic usti-orthic primosols.In addition,according to the classification standards for soil family and soil series,6soil families as clay loam and siliceous mixed type with acidic and hot typic acidic-udic argosols,and7soil series as Gaoshen series(43-CS16)are established.
