It is concluded that, first, geochemical data of the surface soils can clearly distinguish two kind of soils, that is, juvenile soils, for example, purple soils, which inherits most geochemical characteristics of the parent rocks or materials, and anthropic soils, the geochemical characteristics of which have been greatly changed as the results of intensive impact from variety of agricultural uses. Second, different soils have typical indicator elements association respectively due to different parent rocks or materials and utilization, such as purple soils, yellow soils (low alkali and alkaline-earth metal contents and pH value), paddy soils (high organic element and heavy metal elements contents) and fluvo-aquic soils (high rock-forming accessory mineral elements contents) and so on. Consequently, it can be suggested that elements association is an important indicator for two key factors (parent materials and anthropic activities) of soil classification. Third, some differences exist between soil genesic classification and result of cluster analysis, because geochemical characteristics of surface soils can not completely represent the foundation applying to soil genesic classification, that is, condition and process of soil-forming, and soil property.

结果表明：浅层土壤的地球化学数据能较好地用来区分两类土壤，即紫色土一类的幼年土壤（在很大程度上继承了母岩、母质的地球化学特征）和受强烈人为活动水耕、早耕熟化的土壤（外来物质的不断加人显著地改变了浅层土壤原有的地球化学性质）；(2)各类土壤因母岩母质和利用方式不同，各具明显的标志性元素组合特征，如紫色土、黄壤（低碱和碱土金属元素和pH值）、水稻土（高有机元素、肥料元素和重金属元素）和潮土等，因此，这些元素组合是土壤分类两个要素的重要参照系；(3)浅层土壤的地球化学特征不可能完整地体现成土条件、成土过程和土壤属性这三个发生分类依据，因此，聚类分析结果与发生类型之间存在一定的差异。
