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。 The study on the soil in Hanzhong Basin by using the system of systematic classification and numerical classification shows that there are obvious differences in the morphology, occurrence characteristics and soil forming process of soils developed at different parent materials and altitudes, and should be distinguished above the soil level To: where the development of clay loamy soil on the soil as leaching soil class, iron moist leaching soil soil; developed in bedrock weathering material on the soil as iron-rich soil class, sticky moist iron-rich soil The soil distributed in the warm temperate zone in Zhongshan is leaching soil, and the soil is easy to wet and leaching soil.
