| 摘要: |
| 应用系统分类体系和数值分类方法对汉中盆地土壤进行研究表明，发育在不同母质和海拔高度的土壤，剖面形态、发生特性和成土过程均存在明显差异，应在土类以上的等级上区分开来：其中发育在粘黄土母质上的土壤为淋溶土纲、铁质湿润淋溶土土类；发育在基岩风化物母质上的土壤为富铁土纲、粘化湿润富铁土土类；分布在中山区暖温带湿润地区的土壤为淋溶土纲、简育湿润淋溶土土类。 |

| Abstract: |
| By means of taxonomy and numerical classification,the soils in Hanzhong Basin were studies.The results obtained are summerized as follows:The soils developed in the different parent materials and altitude of Hanzhong Basin are signifacantly different in profile forms,pedogenic characteristics and forming processes.The soils should be divited in groups,of which the soil developed in the parent materials of argic-loess is classified to be Fer-Udic Luvisols;the soil developed in the parent materials of weathering products of basement rock to be Arg-Udic Ferrisols;and the soil developed in the humid and warm region at mountain waist area to be Hap-Udic Luvisols. |
