Abstract： In this study, we systematically researched and comprehensively analyzed dominant plants in typical deserts in China, including Tarim Basin, Junggar Basin, Horqin Sandy land, and Hunshandak Sandy land, and revealed the characteristics of stress adaptation and stable restoration of dominant vegetation, and proposed the sustainable management technology of vegetation. The results are shown as the followings. (1) Desert plant roots remain connected to underground diving or soil capillary water. It is of great significance to maintain reasonable ecological water use and stable groundwater table for the restoration and conservation of dominant woody plants in these regions. (2) The shallow soil water formed by groundwater, snowmelt, and rainfall is the main water source of Haloxylon ammodendron (C. A. Mey.). It is of great significance for the restoration and conservation of H. ammodendron to make full use of the natural law of seasonal change of precipitation and the renewal of H. ammodendron to form scientific and reasonable planting technical measures. (3) Closure protection plays an important role in the stable restoration of dominant vegetation in desert (sandy land). The results can provide scientific basis and technical supports for the restoration and optimal management of dominant vegetation in the oasis-desert transition zone in arid region.
