中文摘要	选取典型沙漠绿洲城市(乌海、石嘴山、银川)表土为研究对象,对其环境磁学性质、土壤质地与重金属含量分布进行系统研究.结果表明,乌海市和石嘴山市表土为典型砂土,银川市为砂壤土.三个城市表土样品均以较粗的MD-PSD颗粒的亚铁磁性矿物(磁铁矿)为主导,磁化率均值分别为152×10-8、104×10-8和117×10-8 m3·kg-1.乌海市表土磁性矿物含量和磁性颗粒大小都显著高于石嘴山和银川市.重金属(Cr、Cu、Pb、Zn、Fe)的污染负荷指数(PLI)均显示,三个城市表土均存在轻度污染特征.同时磁化率和污染负荷指数在非工业区表现出点状高值分布,在工业区表现为面状高值分布特征.乌海市表土磁参数与...
