摘　　要：近年来随着基础工程建设的快速实施,各类开挖边坡的数量逐年增加,由此引起的坡面水土流失、浅层滑坡等地质灾害呈显著增长趋势,给区域生态环境造成了严重的影响。为了科学有效地探讨解决这类环境地质问题,国内外学者开展了大量有关植物固土护坡理论方面的研究。在简论述植物护坡发展历史的基础上,着重探讨了根-土复合体的剪切试验及其力学模型的研究现状,并从根系特征对土体抗剪强度的影响、根-土复合体剪切试验、根-土复合体力学模型等3个方面论述了该研究领域的发展趋势。In recent years,along with the rapid implementation of foundation construction,the number of various types of slope excavation has been increased year by year,which has caused serious geological hazards such as soil erosion of slope surface and shallow landslides.These hazards have had serious influence to the regional ecological environment protection.In order to investigate and solve the problems concerning geological environment scientifically and effectively,the scholars both at home and abroad have made a great deal of research on consolidating soil and protecting slope by plant roots.Based on the systematical explication of the development of slope protection by plants,the paper emphatically discussed the shear test of root-soil complex and the present status of its mechanical model study and explicated the development trend of the studied area from three aspects of influence of the characteristics of root system to the shearing resistance of soil mass,shear test of root-soil complex and the mechanical model of root-soil complex.
