摘　　要：沙生植物在风蚀防治中起着至关重要的作用,长期的适应结果使其形成了特定的构型特征。构型特征不同,其抗风蚀的作用也不尽相同。过去的研究主要着眼于个体或群体组合,探讨沙生植物对近地面流场的影响和固阻沙作用。对于构型特征,主要从构件水平上探讨不同构型特征的沙生植物对环境的适应对策,而其抗风蚀作用的差异,还缺乏量化研究和系统探讨。本文评述了沙生植物构型及其与抗风蚀效果关系的研究进展,指出了今后需要优先深入研究的重点问题,从而为完善沙生植物抗风蚀机理提供科学依据。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.
