摘　　要：通过对唐山近地表降尘中8种重金属元素含量的统计与分析,发现重金属元素存在着较强的差异,表明重金属污染的分布极不均匀;应用地统计模块中的Kriging空间插值分析方法,对这8种重金属元素含量进行插值成图,结果表明,8种重金属元素的分布特征都存在一个相似的高值异常区,此异常区出现在以南湖公园为中心的区域上,向东北、西北方向延伸;利用因子分析法,得出唐山市区近地表降尘重金属的主要贡献源以燃煤和交通为主。这些研究为全面了解唐山市区的空气质量状况和该市大气环境污染治理、城市规划提供基本信息。Based on statistics and analysis of eight heavy metal elements in near-surface atmospheric dustfall of Tangshan,the authors found the existence of obvious differences and the uneven distribution of heavy metal pollution.Based on the Kriging interpolation analysis of the eight heavy metal elements in near-surface atmospheric dustfall,the authors have reached the conlcusion that the distribution features of the eight kinds of metals have a somewhat identical high value in this area,with the South Lake park as the center.This anomaly area extends northeast and northwest.Based on principle component analysis,it is held that the heavy metals in near-surface atmospheric dustfall of Tangshan are mainly attributed to coal and traffic sources.The results obtained provide basic information for the understanding of the air quality and atmospheric environment pollution in Tangshan City and the performance of urban planning.
