摘要: 本文介绍了线形沙丘不同部位风沙沉积物的粒度特征、易溶盐含量特征和颗粒形态特征,通过现场全断面开挖线形沙丘剖面,对线形沙丘的内部构造进行了观测,结合研究地区的风信资料,对线形沙丘的风沙堆积过程进行了初步分析研究。

关键词: 线形沙丘, 风沙沉积, 内部构造, 粒度参数

Abstract: This paper described the grain-size characteristics of different parts of aeolian sand,soluble salt content and grain-shape features of linear sand dunes in Qaidam Basin,The profiles and internal structures of linear sand dunes were observed in the field and their depositional processes were analysed based on local wind data.

Key words: Linear dune, Aeolian sand, Grain-size parameter, Depositional structure
