中文摘要：

2013年4月20日，四川省芦山县发生了Ms7．0地震。文中简要介绍了芦山地震的基本情况与芦山地震区历史地震及其相关地震滑坡情况。依据2008年汶川地震滑坡与地震动峰值加速度（PGA）的空间关系，对芦山地震滑坡大体分布范围进行了推测。根据地震滑坡分类学，将芦山地震滑坡分为破坏型滑坡、连贯型滑坡、流滑型滑坡3大类。其中，破坏型滑坡包括岩质崩塌、岩质滑动、岩质崩滑、土质崩塌、土质滑动等5类；连贯型滑坡包括土质坍塌与慢土流2类；流滑型滑坡为快速流滑。破坏型滑坡如岩质崩塌、岩石滑动、土质崩塌这3类是芦山地震滑坡中最常见的类型。基于震后可利用的高分辨率航片，初步解译得到3883处滑坡位置点数据。最后，从余震对滑坡的影响，芦山地震滑坡与邻区地震滑坡对比分析，对后续基于高分辨率遥感影像的滑坡精细解译的启示等3个方面开展了分析与讨论。

英文摘要：

On April 20,2013, a strong earthquake of Ms 7.0 struck the Lushan County, Sichuan Province of China. In this paper, basic information of the April 20,2013 Lushan earthquake, historical earth- quakes in the Lushan earthquake struck area and associated historical earthquake-triggered landslides were introduced firstly. We delineated the probable spatial distribution boundary of landslides trig- gered by the Lushan earthquake based on correlations between the 2008 Wenchuan earthquake-trig- gered landslides and associated peak ground acceleration （PGA）. According to earthquake-triggered landslides classification principles,landslides triggered by the earthquake are divided into three main categories： disrupted landslides, coherent landslides, and flow landslides. The first main category in- cludes five types： rock falls, disrupted rock slides, rock avalanches, soil falls, and disrupted soil slides. The second main category includes two types of soil slumps and slow earth flows. The type of flow landslides is mainly rapid flow slides. Three disrupted landslides, including rock falls, disrupted rock slides,and soil falls are the most common types of landslides triggered by the earthquake. We preliminary mapped 3883 landslides based on available high-resolution aerial photographs taken soon after the earthquake. In addition,the effect of aftershocks on the landslides,comparisons of landslides triggered by the Lushan earthquake with landslides triggered by other earthquake events, and guidance for subsequent landslides detailed interpretation based on high-resolution remote sensing images were discussed respectively. In conclusion,based on quick field investigations to the Lushan earthquake, the classifications, morphology of source area, motion and accumulation area of many earthquake-trig- gered landslides were recorded before the landslide might be reconstructed by human factors, after- shocks, and rainfall etc. It has important significance to earthquake-triggered landslide hazard mitiga- tion in earthquake s
