Based on an analysis of the formation mechanism, stability state and development trend, this paper focuses on monitoring key indicators, such as surface deformation and rainfall, to realize the early warning of landslides and provide some guidance for landslide disaster prevention and avoidance in the alpine mountainous area of Nangqian, Qinghai Province. The landslide of the Baima Elin Monastery has the topographic and geomorphological conditions of landslide formation and has the basic characteristics indicating that it can be influenced by rainfall and climate, so a landslide warning should be comprehensive. At the same time, the landslide is currently in an unstable state, and the seasonal freeze-thaw cycle will cause it to become more unstable. Based on macroscopic signs, it is predicted that the deformation of the Baima Elin Monastery landslide will continue to intensify without abatement, the stability will be further reduced after winter, developing in an unfavorable direction, and engineering measures should be taken as soon as possible to manage the landslide.
通过对形成机制、稳定状态和发展趋势的分析，本文着重监测地表变形、降雨等关键指标，以实现滑坡预警，并为青海省囊谦县高山山区的滑坡灾害防治与避让提供一定指导。白马寺林滑坡具备滑坡形成的地形地貌条件，且具有可受降雨和气候影响的基本特征，因此滑坡预警应全面。同时，该滑坡目前处于不稳定状态，季节性冻融循环会使其更加不稳定。基于宏观迹象预测，白马寺林滑坡的变形将持续加剧且无减弱趋势，冬季过后稳定性将进一步降低，朝着不利方向发展，应尽快采取工程措施治理滑坡。
