南通城郊土壤重金属背景值和元素间相关性分析

Analysis of Correlation among Heavy Metals Elements and Background Value of Heavy Metal Elements in Soil of Nantong Suburb

[目的]为土壤环境质量的评价和预测以及环境标准的制定、环境管理和环境规划等提供依据。[方法]采用相关分析、主成分分析和系统聚类相结合的方法,探讨南通城郊土壤重金属元素间的相关性。[结果]土壤重金属元素的相关性分析可以反映南通土壤中重金属元素的共性。[结论]通过对南通土壤中重金属元素的共性分析,发育其上的土壤能反映全区域土壤中相同的元素共生组合规律。

[Objective]The research aimed to provide the basis of soil environmental quality assessment and prediction,environmental standard establishment,environment management and environment plan,etc.[Method]The correlation among heavy metal elements in the soil of Nantong suburb was probed into by combining correlation analysis,principal component analysis and hierarchical cluster analysis.[Result]The correlation indicated general characteristics of heavy metal elements in the soil of Nantong suburb.[Conclusion]Through general characteristics analysis of heavy metal elements,the soil development could indicate the laws of paragenetic association of the same elements in the soil of Nantong suburb.
