| 摘 要： | 根据青藏高原隆升具有持续性和阶段性加速的特征,将其整个隆升过程分为 4个隆升阶段 15个隆升幕,即喜马拉雅运动（6个加速隆升幕）---递进式压缩隆升阶段;青藏运动（3个加速隆升幕）---构造变形、断裂运动性质调整阶段;昆黄运动（3个加速隆升幕）---高原造貌主阶段;共和运动阶段（3个加速隆升幕）---地质灾害高发期。由于青藏高原的强烈隆升,最终使其成为我国地质灾害最为严重的地区之一。尤其是青藏高原周缘西北部的黄河上游
流域、东南部的长江上游流域、西藏南部的雅鲁藏布江下游区及其东南部的"三江地区",成为地质灾害事件集中发生的区域,其中的地震、崩滑流、断裂活动等地质灾害效应最为强烈,成为影响现代人类工程活动和生存环境的主要灾害。

| Abstract: | Based onthe feature of continuity and stage accelerationof Qinghai-Tibet Plateau uplift, overall uplift process is divided into four stagesand fifteen uplift-episodes, namely Himalayan tectonic movement(six accelerate-uplift episodes)-progressive compressing-uplifting stage, “Qinghai-Tibet” tectonic movement(three accelerate-uplift episodes)-the adjustment on tectonic deformation and fault-kinematics, “Kunlun-Yellow river” tectonic movement(three accelerate-uplift episodes)-the geomorphologic-shaping period, “Gonghe” tectonic movement(three accelerate-uplift episodes) high development period of geological hazards. Owing to the strong uplift of Qinghai-Tibet plateau, the plateau eventually turn into one of region that the geological hazards are most severe in China. Especially the drainage area of upper reaches of Yellow River in northeast Qinghai-Tibet Plateau , the drainage area of upper reaches of Yangtse river, lower reaches of Brahmaputra in southern Tibet and the upper reaches of Nujiang river, Lancangjiang river and Jinshajiang river in southeastern Tibet, are centralized areas that geological hazards occur, in which the earthquakes, rockfalls, landslides and mudflows are most typical, severe, and mostly hazards in human modern engineering activity and living environment. |
