초록

Pull-out resistance tests of root were carried out for 7 shrub species which are mainly used greening of deteriorated forest slope. Mean pull-out resistance forces of Aralia elata, Salix koreensis and Stephanandra incisa were 37.26 kgf, 34.56 kgf and 26.00 kgf, respectively. The pull-out resistances were high as collar diameter and volume of the root increased. Correlations between root collar diameter and root volume were high in Rubus crataegifolius, but on the other hand, the correlation was lowest in Zanthoxylum schinifolium. There were significant differences in pull-out resistance by root collar diameters, and the difference of pull-out resistance by species showed only below 20 ml root volume.
