研究了生长于陡坡上的刺槐根系在土体中的分布规律及其单根抗拉强度.结果表明：在研究区特殊的生境影响下,随着深度的增加(0～50 cm)和树位的不同,刺槐根系中毛细根和细跟的分布表现出不同的变化特征.根系抗拉力随着直径的增大而增大,分布规律表现出明显的指数特征,最大峰值拉力达1461 N,根系最大抗拉强度达72.20 MPa,并且随着直径的增加表现出一定的降低趋势.生境对于刺槐根系的分布和抗拉性能产生了较大的影响.刺槐能够在无灌溉条件下正常生长,是本区域控制松散堆积物侵蚀或运移的理想树种之一.

The distribution patterns and tensile strengths of the Robinia pseudoacacia Linn. roots growing in steep slopes were studied and the results showed that, in such a special habitat, with the increasing depth (0–50 cm) and on different positions of the slopes the distribution of the roots within different diameter classes showed different characteristcs. The tensile strength increased as the diameter increased, and the trend demon-strated an obvious index distribution of the peak force with a maximum value of 1 461 N. The maximum tensile strength was 72.20 MPa, and changed in a decreasing trend with the increasing diameter. Habitat had a greater influence on the distribution of the root systems and tensile properties. This kind of trees could grow in such a harsh habitat without the help of human intervention, presenting themselves as an important tool in controlling loose deposits.
