中文摘要	近年来,利用黄土磁化率各向异性/磁组构(AMS)研究古风向变化被广泛应用.在对祁连山东北缘厚75.5m的中路黄土剖面岩石磁学和磁组构研究的基础上,恢复了该区1.4Ma以来古风向变化序列.磁组构指示的古风向表明,在1.4～0.78Ma期间,本区的地面主导风向为NW-SE;从0.78Ma开始,地面主导风向逐渐向NE-SW过渡;至0.5Ma时,该区地面主导风稳定为NE-SW向.对青藏高原隆升的研究显示,在1.2～0.8Ma期间青藏高原发生过称为“昆黄运动”的大规模隆起.结合我们对主导风向变化驱动因子的分析表明,祁连山东北缘近地面主导风向的第一次转变很可能是同时期青藏高原构造强烈隆升对大气环流影响产生...
