中文摘要：
利用汶川地震次生地质敏感性评价模型,以距发震断层的距离、地形坡度、地层岩性、距离水系的距离、海拔高度、PGA为评价因子,对＂4.20＂芦山地震地质灾害的空间分布进行了快速预测,为野外调查工作提供参考。预测结果显示芦山地震次生地质灾害敏感性高的区域主要是芦山、宝兴、天全、雅安、荥经等县市的山区,并主要集中分布于发震断层附近的芦山县大川镇、宝盛乡、太平镇、双石镇、宝兴县灵关镇、天全县小河乡等区域。
英文摘要：
Based on the susceptibility evaluation model of the co-seismic geohazards in the Wenchuan earthquake, this paper adopts 6 influencing factors including the distance from the seismic fault, topographic slope, lithology, the distance from river system, elevation and PGA to make a fast prediction for the spatial distribution of geohazards triggered by the ＂4 ·20＂ Lushan earthquake. The preliminary results suggest that the zones with high susceptibility of co-seismic geohzards are mainly distributed over the rural areas of some counties and cities including Lushan, Baoxing, Tianquan, Ya＇an, Yingjing and Qionglai in Sichuan Province, and concentrate in the areas near the seismic fault, that is, the front Longmenshan fault, including Dachuan town, Baosheng village and Shuangshi town of Lushan County, Lingguan town of Baoxing County, and Xiaohe town of Tianquan County.
