为了探明湖南省郴州市典型土壤在中国土壤系统分类中的归属,选取郴州市8个典型土壤剖面,通过查阅资料、野外调查取样和室内分析,参照《中国土壤系统分类检索(第三版)》和中国土壤系统分类土族和土系的划分标准,确定其诊断层、诊断特性及在中国土壤系统分类中的归属。结果表明:8个典型供试土壤剖面含有暗瘠表层、淡薄表层、黏化层、低活性富铁层、雏形层5个诊断层,铁质特性、铝质现象、准石质接触面、土壤水分状况(常湿润、湿润)、土壤温度状况(热性)5个诊断特性与现象;由此检索出富铁土、淋溶土、雏形土、新成土4个土纲;湿润富铁土、湿润淋溶土、常湿雏形土、湿润雏形土、正常新成土5个亚纲;黏化...

In the present study, eight typical upland soil profiles in Chenzhou City were selected to study the soil genetic characteristics and their attribution to Chinese Soil Taxonomy. After collecting the relevant soil information, field surveying and laboratory analyzing, the diagnostic horizon and characteristics of soils in Chenzhou City were determined and their attribution to Chinese Soil Taxonomy were identified on the base of “the keys to Chinese Soil Taxonomy (3rd edition)” and “Chinese classification standards of soil family and soil seri...
