Abstract The deserts in the world are mainly distributed in the subtropical zone, only the deserts in China are in the temperate zone. Based on the relevant literature and the survey of sandy desertification in China in 1994, the current situation of draught and sandy desertification both at home and abroad are introduced, the factors influencing the formation and distribution of the deserts in the north of China are analysed. The major factors include the rising of the Qinghai-Ti-bet Plateau, the effects of the last glacial epoch, the water and soil resources, the climate changes, and the unreasonable human activities. The future development tendency of sandy desertification is predicted and the trans-regional water diversion projects, the water-saving forestry and husbandry and the combating of sandy desertification according to laws should be speeded up for the purposes of fundamentally controlling the draught and desertification in the north of China.
