Vegetation in landslide area is difficult because of barren, water stress, coarsetextures soils, and steep slopes etc. In this study we need to construct the criteria of Landslide Areas protection for the selected vegetation materials in considering their characteristics and the soil solidities for the root system. With the destructive pulling resistance models, with the weight of plant above the ground(Wu) or the weight of root-soil(Wd), and the non-destructive resistance models, with the diameter of the tree just above the ground(D, mm), were derived with multi-variable regression analysis, respectively. The models gave higher statistical regression coefficients when they were compared with the results of relative researches. The significant level factors to influence the plant pulling resistance capacity are climate and soil properties. Finally the relevant conclusions were obtained.
