The production, transport, and deposition of dust has profound impacts and feedbacks on the regional and global environments. In parallel, the Tibet Plateau (TP) plays an important role in East Asian and global climate systems. Previous studies have shown that the dust can reach the plateau by long-distance transport from the westerlies and by short-distance transport from regional weathering. Here we present three new datasets in the Qilian Mountains of the northern TP, including two mountainous aeolian sedimentary sequences and a surface sample dataset. Proxies include grain size, magnetic susceptibility, mineral composition, total organic carbon, and total nitrogen. Data from surface samples indicate spatial gradient effects in altitude (from low to high) and latitude (from north to south), suggesting dust transport from the Gobi Desert to the plateau. The synthetic analysis of two aeolian sedimentary sequences and paleoclimate simulation data reveals that the northern TP can be a dust transport channel controlled mainly by the Asian winter monsoon and less influenced by the westerlies.

粉尘的产生、输送和沉积对区域和全球环境具有深远的影响和反馈。与此同时，青藏高原（TP）在东亚和全球气候系统中发挥着重要作用。以往的研究表明，灰尘可以通过西风带的长距离输送和区域风化作用的短距离输送到达高原。在这里，我们展示了青藏高原北部祁连山的三个新数据集，包括两个山地风成沉积序列和一个地表样本数据集。替代指标包括粒度、磁化率、矿物成分、总有机碳和总氮。来自地表样本的数据表明高度（从低到高）和纬度（从北到南）的空间梯度效应，表明沙尘从戈壁沙漠向高原输送。两个风成沉积层序和古气候模拟数据的综合分析表明，青藏高原北部可能是主要受亚洲冬季风控制，受西风影响较小的沙尘输送通道。
