| 摘 要： | 选择汶川县境内的都汶公路(漩口-汶川路段)作为调查研究对象,利用遥感技术提取公路沿线的各类地震次生山地灾害的分布信息,将灾害点分布与海拔高度、坡度和坡向等要素进行叠加分析,获得了次生山地灾害的分布规律,其特点为:①地震次生山地灾害集中分布在映秀-北川断裂与汶川-茂汶断裂之间;②次生山地灾害主要发生在海拔高度1 000～2 000 m的地带;③次生山地灾害主要分布在30～60°的边坡;④地震及余震期间以崩塌、滑坡、滚石为主,后期以泥石流、滑坡为主;⑤次生山地灾害具有沿岷江河谷发育且在河流左右两岸呈不对称分布等特点. |
| 关 键 词： | 地震次生山地灾害 汶川地震 分布规律 遥感 都汶公路 |
