【摘要】 本文对某城市表层土壤八种重金属(As、Cd、Cr、Cu、Hg、Ni、Zn、Pb)的污染进行了分析研究.根据统计数据来构造经验分布函数分析引起八种重金属污染的主要原因.从而,避免了繁琐的外部因素的机理分析.结果表明,运用统计学的方法为分析城市表层土壤重金属的污染提供一种更加有效的理论依据.更多还原

【Abstract】 The eight kinds of heavy metals(As,Cd,Cr,Cu,Hg,Ni,Zn,Pb) pollution of surface soil in a city are studied in this paper.According to the statistical data to construct the empirical distribution function,the main cause of eight heavy metals pollution is analyzed in this paper.Thus,a lot of external factors of mechanism analysis can be avoided.The results show that the analysis of surface soil heavy metals pollution of the city can provide a more effective theory basis using statistical method.更多还原
