摘　　要：汶川8.0级地震灾区恢复重建的防灾形势严峻,灾后恢复重建的防灾关键就是选址问题。在重建前要充分评估灾害孕育的地形地貌、地层岩性、地质构造等环境条件,有效避让破坏性的崩塌、滑坡、泥石流、堰塞湖等次生山地灾害,同时对不可避让灾害采取适当的预防和治理措施。防灾从重建前的选址开始,科学选址,有效防灾,是选址防灾的总体思路。The situation of disaster prevention in restoration and reconstruction of stricken areas of the M8.0 Wenchuan earthquake is rather grim in restoration.The key issue of it is site selection.So,it is badly needed to make a sufficient assessment on the environmental conditions as topography and geomorphology,stratum lithology,geological structure that are favorable to hazard development,aiming at effectively keeping away from locations prone to secondary mountain hazards such as collapses,landslides,debris flows,and barrier lakes.Meanwhile,appropriate prevention and control measures should be taken to prevent unavoidable hazards.Site selection in reconstruction should be considered as the very first step for disaster prevention.Selecting sites scientifically and preventing disasters effectively are the general idea of site selection for disaster prevention.
