摘要

摘要: 2013年4月20日，四川芦山县发生7.0级地震。由于当地复杂的区域地形条件，强烈的地震引发了大量的滑坡、崩塌等次级地质灾害。以此次地震诱发滑坡的重灾区宝盛乡为研究区，采用遥感高清影像与DEM结合的方式进行目视解译，并结合光谱信息与坡度信息对目视解译结果进行半自动提取与再验证，建立地震斜坡灾害的光谱信息解译标志；在此基础上，利用GIS空间分析功能，统计分析此次地震斜坡地质灾害在地形地貌、地层岩性、构造等方面的发育规律。结果表明，本次地震诱发滑坡规模以中小型为主，坡度范围主要集中在30～50，发育的地层主要为下第三系名山组和白垩系灌口组粉砂岩、泥岩、砾岩；烈度范围主要集中在Ⅸ度区。

Abstract: On April 20, 2013, a strong earthquake of MS 7.0 struck the Lushan County, Sichuan Province, China. Because of the complex terrain conditions of the local area, the strong earthquake triggered numbers of secondary geological disasters, such as landslides, collapses, and debris flows. The Baosheng country, seriously attacked by slope mass movement disasters, was taken as an example for the study area in the paper. The combination of the remote sensing images and the DEM is used for visual interpretation. To evaluate and modify the accuracy of the visualization result, the spectral information and gradient information are then utilized. Moreover, the technology of spatial analysis and statistical analysis method is applied to the analysis of regularity of landslide mechanism, including topography, lithology, geological structure, and seismic intensity. The results show that the slopes of the earthquake-induced landslides are mainly concentrated in the range of 30～50,developed primarily in Mingshan group of earlier-Tertiary strata and Guankou group of Cretaceous composed of siltstone, mudstone and conglomerate, and mainly in the area of intensity Ⅸ.
