【摘要】 对宣郎广岗丘地区40个土壤剖面,按中国土壤系统分类体系,进行鉴别、检索、分类定名。阐述土壤发生分类体系的11个亚类级土壤类型在中国土壤系统分类中归为5个土纲,即人为土、富铁土、淋溶土、雏形土和新成土;5个亚纲,即水耕人为土、湿润富铁土、湿润淋溶土、湿润雏形土和正常新成土;15个土类和23个亚类。参比关系复杂,不是简单的一对一的关系。提出按中国土壤系统分类的该区土壤分类系统;并讨论了该区土壤发生分类与系统分类之间具体土壤类型的对应关系。研究结果对土壤类型的正确参比、中国土壤系统分类的应用与发展、具有很好的参考应用价值。更多还原

【Abstract】 Forty soil profiles in the hilly region of Xuan Lang Guang,Anhui Province were identified and classified according to the keys to the Chinese Soil Taxonomy(CST)(the 3rd edition).The placement of 11 taxa,formerly sorted on the subgroup level of the Chinese Soil Genetic Classification System(CSGC),in CST was elucidated in the paper.All these soils studieds are classified into 5 CST Orders: Anthrosols,Ferrosols,Argosols,Cambosols and Primosols,5 CST Suborders: Stagnic Anthrosols,Udic Ferrosols,Udic Argosols,Udic Cambosols and Orthic Primosols,15 CST Group and 23 CST Subgroups.The correlation of Soil taxa between CSGC and CST was so complicated that there is almost no one-to-one correlation of soil taxa.The taxonomic soil classification of the hilly region of Xuan Lang Guang was proposed in the paper.And correlation of taxa between CSGC and CST was also discussed.The results of the study are of high reference value to proper correlation of soil taxa between CSGC and CST and development of CST.更多还原
