Abstract: Psammophyte plays an important role in wind erosion control. The long-term adaptation of psammophyte to wind erosion makes the plant have specific architecture characteristics. Previous studies mainly focused on the effects of the individuals or a group of psammophyte on the near surface air flow field and sand fixation and resistance. As for the architecture characteristics of psammophyte, the research covered all of the adaptation strategies, lacking of quantitative research and systematic analysis on the discrepancy against wind erosion. This paper reviewed the research progress on psammophyte architecture and its relations with the capability of anti-wind erosion, and pointed out the key issues needed to be further studied to provide scientific basis for perfecting the mechanisms of sand plant resistance to wind erosion.
