摘要
在大量调查、观测、试验、测试的基础上，运用主成分分析和聚类分析方法对沙珠玉地区风沙土的８个典型剖面进行了数值分类，得到了满意的结果。正确地区分了风沙土和当地地带性土壤栗钙土，划分出风沙土类石灰性风沙土亚类的三个土属，即流动石灰性风沙土、半固定石灰性风沙土和固定石灰性风沙土，与传统分类和系统分类的结果一致。
Based on a mass of data from survey, observation, experiment and testing, the numerical taxonomy to blown sand soils at 8 typical profiles was made with principal component analysis and cluster analysis methods. The results were satisfing: the difference between blown sand soil and zonal chestnut soil was differentiate correctly, the 3 genus of calcaric blown sand soil subcrops classified with the above method coincided with the results of classic and systematic taxonomy, and they were shifting, semi fixed and fixed calcaric blown sand soils. The method is a new trying in blown sand soil taxonomy, which will lay the foundation for blown sand soils numerical taxonomy.
