摘要：

A preliminary study of the Malan loess on the eastern margin of the Qinghai-Xizang(Tibetan)Plateau and its adjacent area shows that along the boundary of Kunlun Mts.-Buqing Mts.-A’nymaqnMts.-South Qinling(Motianling),the Malun loess falls roughly into two main depositional regions:to itsnorth,a hot loess region in which dusts come mainly from the Asian inland arid area;to its south,a coldloess region in which dusts come chiefly from the Qinghai-Xizang Plateau.The possible causative fac-tors and processes for the loess difference are the uplift of the Plateau and the effects of its resultant particuolar landform,the interactions of its induced Asian monsoon,by-flowing westlies and plateau monsoon,and thedifference of sediments of source areas.
