摘要: 川西高原位于青藏高原东缘,是崩塌、滑坡和泥石流等突发性地质灾害的群发地,具有分布基本沿活动构造带走向、发生时间较集中、人类活动诱发的地质灾害数量增多和地质灾害链后果严重等特点,主要受地质构造、现今构造运动、地形地貌、降雨及人类不科学的社会、经济和工程活动等多种因素影响。

Abstract: The western Sichuan plateau lies on the eastern margin of the Qinghai-Xizang Plateau,where abundant violent geologic hazards such as collapse,landslide and debris flows frequently occur because of complx geological tectonics,active endokinetic/exokinetic processes and severe tectonization.These geologic hazards are generally aligned along active structural zones, and mostly controlled by geological structures,present-day tectonic movements,topography and geomorphology,rainfalls and human’s activities in the study area.
