摘　　要：植物柔韧性是沙生植物抗风蚀的重要影响因子,柔韧性的研究可对风蚀治理措施的选取及沙地风蚀方程的建立提供一些理论依据。回顾和总结国内外植物柔韧性的研究现状,提出沙生刚性植物和柔性植物的概念,指出现在研究中的不足和今后的研究方向即植物柔韧性的量化测定,柔性植物及刚性植物作用机理,柔性植物与刚性植物的划分和界定,以及植物柔韧性在风洞中的模拟。Flexibility of plant is a significant factor for psammophytes preventing wind erosion.Application of flexibility concept could provide some theoretical basis for selection of erosion control measures and establishment of the sand wind erosion equation.In this paper,both domestic and international research status for flexibility of plant were reviewed.Then we brought forward the concept of flexible and rigid desert plants,and analyzed the deficiency of the present research.The future research directions include： a quantitative determination of plant flexibility,mechanism of flexible and rigid plants,division and definition of both of them,as well as simulation of flexibility in wind tunnel.

关 键 词：沙生植物 柔性植物 刚性植物 柔韧性
