探讨汶川地震诱发地质灾害的发育分布特征.利用航空影像对青川县红石河区域进行遥感解译,并结合汶川地震前研究区地质灾害调查数据进行对比分析.在193 km2的范围内共解译地质灾害712处,其中,滑坡209处,崩塌486处,泥石流17处,地质灾害发育密度达到了3.7 km-2.汶川地震诱发的地质灾害具有明显的断层上下盘效应、坡度效应、灾害链效应及高密度发育的特点.%This paper makes an approach to the distribution characteristics of the geo-hazards induced by the Wenchuan earthquake and uses the aerial photos to interpret the geo-hazards in the Hongshi river basin of Qingchuan County, Sichuan. It is found that there are 712 geo-hazards in the area of 193 km2 , including 209 landslides, 486 rock falls, and 17 debris flows. The density of the geo-hazards amount to 3. 7 km -2. Compared with the geo-hazards before the earthquake, the distribution of the earthquake-induced geo-hazards has obvious hanging wall footwall effects, topography effects, disaster-chain effects, and high density characteristics.
