21世纪，中国西南部的四川省发生了2008年汶川8.0级地震和2013年芦山7.0级地震。这两次强烈地震造成了巨大的财产损失和大量的人员伤亡。滑坡、泥石流等地质灾害频发，给地震多发区防灾重建工作带来巨大挑战。本研究采用野外调查与高分辨率遥感影像目视解译相结合的研究方法，对地震烈度≥VII的地区进行调查。本研究根据国土资源部、水利部、建设部等相关部门发布的统计数据，系统分析了芦山、汶川地震多发区地质灾害的分布特征。这种澄清是通过地理信息系统技术结合不同的因素组合来完成的。希望通过对芦山和汶川山地灾害分布特征的对比分析，确定地震烈度≥VII地区的分布异同。研究系统总结了研究区独特地貌条件、地质构造等条件下的分布特征；可为类似地区的防灾和人口调整提供参考，促进当地人与自然的和谐发展。
In the 21st century, the 2008 Ms 8.0 Wenchuan earthquake and the 2013 Ms 7.0 Lushan earthquake occurred in Sichuan Province, southwestern China. These two powerful earthquakes caused huge property loss and numerous human casualties. The frequent occurrence of geological hazards (including landslides and debris flows) has brought great challenges to disaster prevention and reconstruction work in earthquake-prone areas. Combing the research method of field investigations with visual interpretation of high-resolution remote sensing images, this study investigates areas with a seismic intensity ≥VII. In the study, a systematic analysis is conducted to clarify the distribution characteristics of geological hazards in the Lushan and Wenchuan earthquake-prone areas based on statistics released by the Ministry of Land and Resources, Ministry of Water Resource, Ministry of Construction of China, and other related departments. Such a clarification was done through GIS technology with varied factor combinations. Hopefully, comparative analysis on the distribution characteristics of mountain disasters in Lushan and Wenchuan leads to determination of distribution similarities and differences in areas with a seismic intensity ≥VII. The study concludes, in a systematic manner, distribution characteristics under distinctive geomorphic conditions, geological structures, and other conditions in the study area; thus can serve as a reference for disaster prevention and demographic readjustment in areas with similar conditions, promoting harmonious development of humans and nature there.
