摘要: 以无锡城乡交错区和郑州市郊区为例,基于土壤学知识,在主成分分析中综合运用土壤基本理化性质和土壤重金属数据对土壤重金属的主要来源进行分析,讨论不同采样方案对主成分分析结果的影响。结果表明:基于土壤学知识的主成分分析有助于增强对数据分析结果的解释,区分土壤重金属的不同来源,但运用该法时应考虑到采样方案对分析结果的影响。

关键词: 主成分分析, 土壤重金属, 来源, 土壤学知识

Abstract: Fristly, the origin of heavy metals in soils were researched with the aid of Principle Component Analyses (PCA) in Wuxi peri-urban area and in Zhengzhou suburb. In PCA, combined with soil heavy metals, soil basic properties were also utilized based on soil knowledge. Secondly, the results of PCA based on different sampling designs were compared. The results of this paper showed that it was helpful to distinguish the sources of heavy metals in soils using PCA based on soil knowledge. However the errors of PCA caused by unreasonable sampling designs should be noticed.

Key words: Principle Component Analyse, heavy metals in soil, sources,soil knowledge
