摘要

通过对汶川地震驱动的通口河流域同震崩塌、滑坡等地质灾害的野外实地考察和遥感影像分析,获得通口河流域同震及震后地质灾害的空间分布情况,结合对通口河流域构造、地貌和气候等因素的分析,获得以下认识:(1)构造因素(汶川地震)是导致通口河流域同震地质灾害的根本原因;(2)地貌因素为同震及震后地质灾害的发生提供了重要的环境条件;(3)以降雨为主的气候因素是导致震后通口河流域地质灾害发生的直接诱发因素。
Through the field research and remote sensing image analysis of the geological hazards,such as the coseismic collapse ahd the landslide of Tongkou River watershed which was triggered by Wenchuan Earthquake,the spacial geo-hazard distribution in Tongkou River watershed was acquired.Further,analysis is made on the tectonic,landforms and climate factors of Tongkou River watershed,and the following conclusions can be drawn:(1) tectonic factor(Wenchuan Earthquake) is the root cause of the coseismic geological hazards in Tongkou River watershed;(2) the;andforms factor is one of important environment conditions to the occurring of coseismic and afte-quake geological hazards;(3) climate factor(mainly Rainfall) is the direct triggering factor which leaded to the occurring of geological hazards in Tongkou river watershed.
