| 摘 要： | 黄棕壤和棕壤在成土环境及成土条件方面有相似之处，但在一系列基本属性上，如ｐＨ、盐基饱和度、铁的氧化物、ｂａ值、粘粒的硅铝率等方面均有较明显的差异，提出用这些定量指标作为划分这２种土壤类型的依据。

| Abstract: | Yellow brown soil and brown soil have samilar aspects in surroundings and conditions of soil formation.However,there are some significant differences in a series of basic attributes,such as pH,base saturation degree,iron oxide,ba value,and clay silica alumina ratio.The two types of soils can be distinguished by using these quantity indexes. |

| Keywords: | exchangable acid iron free degree ba value silica alumina ratio |
