Abstract: In order to research the mechanical mechanism of plants anti-erosion and provide some basis to screen windbreak and soil-reinforcement specie for wind and water complex erosion area. This research selected Caragana microphylla Lam, Salix psammophila C.wang et Ch.Y.Yang, Artemisia sphaerocephala Krasch and Hippophae rhamnides Linn four kinds of soil and water conservation plants of Inner Mongolia Ordos as the research object. During the period of spring gale, thirteen indicators (single shrub reduce wind velocity ration, shelterbelt reduce wind velocity ration, community reduce wind velocity ration, taproots tensile strength, represented root constitutive properties, represented root elasticity modulus, lateral roots branch tensile strength, accumulation surface area, root-soil interface sheer strength, interface friction coefficient, length of accumulative root, root-soil composite cohesive, root-soil composite equivalent friction angle) of foliage windbreak and root mechanical properties were evaluated by the analytic hierarchy process (AHP). The results showed the index of windbreak and soil-reinforcement were in the sequence of Salix psammophila C.wang et Ch.Y.Yang (0.84) > Caragana microphylla Lam (0.45) > Artemisia sphaerocephala Krasch (-0.47) > Hippophae rhamnides Linn (-0.83). Therefore, Salix psammophila C.wang et Ch.Y.Yang could be regarded as the important anti-erosion specie for wind erosion area.
