对系统分类有关诊断指标的认识与讨论

Discussion on the Diagnostic Surface Horizons and the Diagnostic Characteristic in Soil Taxonomy

在进行陕西土壤系统分类研究的基础上,针对《中国土壤系统分类》在应用过程中出现的问题,对堆垫表层、粘化层、雏形层、砂质沉积物岩性特征、黄土和黄土状沉积物岩性特征的基本含义与划分标准提出修改意见,供《中国土壤系统分类》(修订方案)修改时参考。

Based on the study of Soil Taxonomy in Shaanxi province, in connection with the question of using Chinese Soil Taxonomy, authors put forward some suggestions about the meaning and dividing standard of Cumulic epipedon, Argic Horizon, Cambic Horizon, Lithologic characters of sandy deposits and Lithologic characters of loess deposits. This can provide information in revising the Chinese Soil Taxonomy.
