Abstract: Maqu County lies in the southeast of Tibet Plateau, it is the main runoff producing area, water conservation area and water recharging area of the Yellow River and one of the important biodiversity protection areas in the world. However, since the 60s and 70s of the 20th century, the problems of overland runoff decrease, groundwater recession, vegetation deterioration, meadow degeneration and water and soil erosion increased seriously, especially the problem of meadow desertification. In this paper, the authors introduced the desertification condition in alpine meadow in Maqu, discussed the changing process of desertification and the effect of natural factors on desertification in order to provide the basis for further research.
