Abstract: This paper analyses the causes of the destruction of Korqin sandyland, indicating that adverse natural factors and unreasonable human productive activities play a decisive role in the destruction. For its restoration, the principles of developing beneficial and avoiding detrimental factors under local conditions must be persisted, and unreasonable productive ways must be ameliorated. Three types of empirical models for desert management are recommended.
