摘要：

通过对猫儿山的实地考察，选取不同海拔的6个山地土壤剖面进行描述及土壤理化性质分析，研究了猫儿山土壤的形成特征，并按照《中国土壤系统分类：理论?方法?实践》检索，确定各剖面的诊断层和诊断特性及其在土壤系统分类中的位置。结果表明猫儿山土壤形成特征有淋溶作用强烈和富铁铝化特征。B层土壤盐基饱和度低，在12.5%～21.9%之间，而铝饱和度高，在78.1%～86.7%范围；游离氧化铁占全铁含量52%以上，粘粒硅铝率在0.94～2.32之间；猫儿山土壤在系统分类中可划归为2个土纲3个土类。

Abstract:

The climate, plant and soil resources in Maoer mountains in Guangxi were investigated, and the physical and chemical properties of soils of 6 soil profiles in different elevation collected from the mountain were studied. Based on the Chinese Soil Taxonomy, the diagnostic horizons and diagnostic characteristics of the soil profiles as well as related taxonomic classification category were also defined. The results showed that the eluviation, allitization and ferritization in the soil was strong. In the soils of B horizon of the soil profiles, the base-saturation percentage was low, at 12.5%～21.9%,while the exchangeable aluminum saturation percentage were high, at 78.1%～86.7%, and the content of free iron oxide was over 52.0%.The Sa values of B horizons in the soil profiles were 0.94～2.32. There were three groups including two orders in Maoer mountains.
