Abstract	As an important part of Qinghai Plateau, the Qinghai Lake is a sensitive and fragile zone for global change impacts. It is one of the most strongly desertified regions on the Qinghai Plateau. Based on remote sensing, a geographic information system and using Thematic Mapper imagery for the years 1987, 2000, 2009 and Landsat 8 images for the year 2014 as data sources, we extracted information regarding the dynamic changes of aeolian desertification in the study area over the last 28 years. The spatio-temporal evolutions of the landscape patterns of regional aeolian desertified land (ADL) are discussed. Our objective is to provide references for desertification control and eco-environmental restoration in the Qinghai Lake basin (QLB). Results elicit an aeolian desertified area which has increased by 96.74 km$^{2}$ over the past 28 years. ADL mainly experienced processes of increasing stable to decreasing trends, before 2000, the area of aeolian desertification increased by 338.03 km$^{2}$. After 2000, desertification remains stable, but as we speak desertification decreases and a moderate and slight ADL took the lead. The dynamics of aeolian desertification in QLB is mainly determined by climate change, human activities and management.
