摘要: 本文试图通过研究萨拉乌苏河滴哨沟湾第四纪地层中的元素分布,认识该地区第四纪以来气候的变迁与沉积环境。文中指出滴哨沟湾地区晚更新世以来存在三个暖湿期和三个干冷期。风成沙和黄土是晚更新世以来相对干冷气候时期沉积的。

Abstract: It is attempet to understand the climaic changes and the sedimentary environment since the Quaternary Period in Sjara-Osol-Gol District by studying the element distribution in the Quaternary strata at Disiaogou Bay of the Sjara-Osol-Gol River at southeast edge of Mu Us Sandy Land. It is pointed out that there occurred three-warm-wet periods and three dry-cold periods ince the Later Pleistocene period and the aeolian sands and loess were accu mulated during relevant dry-cold climate since the Later Pleistocene period. And it is concluded that the aeolian sands and loess are the sediments in the dry-cold period.
