摘要

简要综述了4.20芦山大地震震区的地质地貌背景及其对次生地质灾害的影响,分析了各种次生地质灾害对林业可能产生的危害,为灾后重建中预防次生地质灾害提供参考。
Lushan earthquake was another destructive earthquake happened in Longmen Mountains structural belt after Wenchuan earthquake.Its quake area included 11 counties along southwest of Longmen Mountain fault zone.Because of peculiar geological structure,topography,and climatic features,earthquake-induced secondary geological disasters such as landslide,falling,debris flow and barrier lake,etc.possessed the characteristic of large numbers,dispersed distribution and Unpredictable.This article stated the catalytic effect of activity,building features of lithology,topography and climatic conditions of Longmen Mountain fault zone on secondary geological disasters,analyzed the damages of secondary geological disasters on forestry,advanced the basic strategy of geological disaster prevention in forestry,in order to provide reference on prevention of secondary geological disasters during the course of post-disaster reconstruction.
