摘　　要：本文对辽南滨海地区的周家沟黄土剖面采集的土样进行磁化率测量,并与中国东部滨海其他地区和黄土高原洛川黄土磁化率进行对比分析,了解到本地区基本与山东长岛磁化率值相同,且略低于镇江下蜀黄土和浪岗山黄土。且本地区磁化率值和变化幅度都明显小于洛川黄土,说明了两地间黄土物源差异和黄土形成时期气候差异。According to the sample from the typical loess profile in Zhoujiagou of the coastal area in the south of Liaoning province, the magnetic susceptibility was to be measured in this paper, compared with the other sites in the coastal areas in eastern China and the mainland, especially in the loess plateau, the magnetic susceptibility in study region is almost the same as that in Changdao of Shandong province, however, the low frequency magnetic susceptibility values are slightly lower than that in Zhenjiang province, the variation amplitude of the mass magnetic susceptibility are significantly less than that of Luochuan loess. The difference of the mass magnetic susceptibility values could be induced not only by the different sources, but also by the different climate.

关 键 词：辽南黄土 环境磁学 磁化率 更新世
