Grassland degradation and desertification have become one of the prominent environmental problems in the Zoigê area.

Because of special regional characteristic and geographical environment, Zoige region in Qinghai-Tibet plateau is very sensitive to climatic change.

Helicopter seeding grass which is an effective way of controlling grassland desertification can improve grassland vegetation coverage, height and yield of grass.

The climatic evolution since the late glacial epoch in the Zoigê area reflected by sporopollen records may be well correlated with the global climate change.

This paper mainly analyzes the natural and anthropogenic causes of grassland desertification in the Ruoergai Plateau using the method of remote sensing and field investigation.
