摘要
调查了福州城市土壤中13种元素的含量,结果表明As、Cd、Cu、Hg、Mn、Pb、Sn、Zn在表层土壤中表现出不同程度富集,在空间上表现出不同程度的异常分布特征,这些元素在城市中心土壤中的含量明显高于外围土壤,其含量受人类活动影响较大;城市土壤中Cr、Ni、Th、U、Fe2O3在空间上含量变化不大,这些元素的分布特征主要受自然背景的影响。
The investigation of content of Cu and else 13 kinds of elements in city soil of Fuzhou, shows that elements （As. Cd. Cu, Hg. Mn, Pb. Sn, Zn） are enriched in topsoil, that elements behaves different extent exceptional distributional characteristics on the space, content of these elements in soil of city center is obviously higher than that of city periphery as a whole, which is mainly affected by mans activity, the content variety of elements （Cr. Ni. Th, U, Fe2O3） in soil on spatial distribution is not obvious, distributional characteristics of these elements is mainly affected by natural background.
