【摘要】 土壤基层分类单元是联系土壤分类与农林生产的桥梁。为促进土壤基层分类与中国国标分类系统的整合，本研究对实体土壤剖面的形态特征和理化性状进行分析，按照国标《中国土壤分类与代码》(GB/T 17296—2009),确定不同土壤剖面的亚类、土属和土种的分类归属。建议在国标栗钙土土类中增加相应的北方红土质土属，并丰富土种的名称。更多还原

【Abstract】 Soil basic category can connect the gap between soil classification and agriculture and forestry production.In order to integrate the soil basic category to national soil genesis classification system, morphological characteristics of soil profiles were observed, and soil physicochemical properties were measured of forestland castanozems located in the eastern region in Qinghai province.Further, the subgroup, soil genus and soil species classified as Castanozems were partitioned according to the China Soil Classification and Code(GB/T 17296-2009),national standards of China.Weakly developed castanozems were supplemented in soil genetic classification system in Qinghai provence, meanwhile, soil genus of categories of paleo-latosol like soils material in North of China in and castanozems were recommended in national soil genesis classification system.更多还原
