| 摘 要： | 位于地质构造、地层、地貌、气侯和植被五位一体叠加脆弱带的陇南地区是我国主要滑坡、泥石流、崩塌等斜坡重力地质作用区之一。本文简述了斜坡重力地质作用的概念和类型，着重分析了其垂直分带性、区域性、季节性、周期性、阶段性、继承性和共生性等作用特征，揭示了斜坡重力地质作用的活动规律。

| Abstract: | Longnan region lies in the translational area among Qinghai-Tibet Plateau,Loess Plateau and Sichuan Basin and belongs to the superimposed weak belt in geological structure,stratigraphic properties, geomorphology, climate and vegetation,so the slope gravitational process,such as debris flow,landslide,rockfall, etc.are most conspicuous in this region,It is one of the four main gravitational disaster areas in China,Based on predecessors works and field investigation,this paper studies the definition and types of slope gravitational processes(SGP),especially analyzes their features, such as vertical zonality.regionality,seasonal variation, periodiclty.inheritability,paragenesis,etc.,thus brings to light their activity laws. |
