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。
3.
Traditional cluster analysis is a practically important technique often used in numerical classification.
传统的聚类分析是常用的重要数值分类方法。
4) taxonomic value
分类价值
1.
The results showed that stem height,stem and inflorescent ramification are multiform in different habitats, and therefore have little taxonomic value.
通过计算分析发现:株高、茎和花序分枝等性状受环境影响较大,因而其分类价值不大;叶形、毛被、叶缘锯齿等性状的变异在居群内是连续的,所以也不是可靠的分类性状;而花部性状的一些变异,包括花瓣的颜色、大小、形态,基本不受环境影响,且这些变异在居群内是不连续的,所以其分类价值相对较高。
2.
The characters of reproductive organ have been the main evidences for the classification of Poaceae, but they are not totally equal in the taxonomic value because of the differences of their dependencies in morphological trait, growth position, developmental degree and environmental alteration.
生殖器官性状一直是禾本科植物分类的主要依据 ,但由于各个性状所附实体的形态特点、着生位置、发育程度和环境饰变的差异 ,其分类价值是不尽相同的。
6) dinary classification
