摘要
对克拉玛依市土壤环境磁学特征进行研究,并探讨土壤磁性增强的机制。结果表明:低频质量磁化率(χLF)在不同用地上依次表现为:交通运输用地>商业用地>林地>公共设施用地>未建设用地>居住用地。交通运输用地、公共设施用地较居住用地、非建设用地的土壤以低矫顽力的亚铁磁性矿物含量较高和少量不完全反铁磁性矿物,且磁性颗粒以多畴(MD)颗粒为主,含少量的单畴(SP)颗粒和稳定单畴(SSD)颗粒,与交通运输用地、公共设施用地受到汽车尾气和其他人为活动产生的污染物中含有大量的粗颗粒亚铁磁性矿物密切相关。
Magnetic characteristics of the soil environment in Karamay City were studied and the soil magnetic enhancement mechanism was explored. The results showed that： The quality Of χLF on different sites as follows： Transport land 〉 commercial land 〉 forest land 〉 land for public facilities 〉 nonconstructive land 〉 residential land. Transportation land, land for public facilities had a higher amount of ferrous magnetic mineral content with a low coercive force and a small amount of incomplete antiferromagnetic minerals than residential land and construction land soil . The magnetic particles was given priority to multiple domain （MD） , containing a small amount of single domain （SP） particles and stable effect （SSD） particles. Pollution contained a lot of coarse particle ferrimagnetic minerals caused by automobile exhaust and other human activities in transportation land, land for public facilities.
