Sand Dunes in the Sanjiangyuan National Nature Reserve.
Loose, dry surface sediments and strong winds are primary factors responsible for aeolian desertification, which is exacerbated by periodic drought often caused by high temperatures and by intensive human activities. The vulnerability of the plateau to aeolian desertification originates from its cold and dry climate, a result of its high altitude, since this climate greatly reduces vegetation growth, and when vegetation is damaged or removed, recovery is slow or unlikely. Increases in temperature, can accelerate melting of frozen soil, causing it to lose its structural support, which in turn promotes the expansion of aeolian desertification.
