摘要：Vegetation restoration design is one of the most difficult designs of rock cut slopes, and reasonable classification study of rock cut slope is fundamental to solving the problem. Therefore, taking rock cut slopes of 5 national and provincial roads as research objects, 144 quadrat samples are investigated on their geological and vegetational conditions. Based on the fundamental principles of geology and restoration ecology, the relationship of slope rock mass characteristics and slope vegetation restoration is analyzed. Slope surface micro-topography is divided into rock bench, rock crevice, rock face and weathered layer. According to those units, a new classification system is put forward. Rock slopes are named as rock face type, rock bench type, rock crevice type, multi-bench and multi-crevice type, and weathered layer type. The main causes of formation, slope characteristics and countermeasures of vegetation recovery of 5 kinds of rock slopes are given. The study results show that multi-bench and multi-crevice type and weathered layer type slopes have good nature restoration effects. © 2014 ejge.
