摘要
依托"5.12"特大地震的抗震救灾工作,以汶川地震12个极重灾县市为研究对象,在1∶5万滑坡详细调查、编录和遥感影像解译的基础上,利用DEM数据、ETM影像及基础地质数据,用证据权法完成了研究区滑坡易发性评价因子的提取与制图以及相关性统计分析,实现了1∶5万的滑坡易发性区划。
Depending on the ＂5. 12＂ huge earthquake relief work, this paper selected the most severity stricken counties in Sichuan as case study areas. Based on the landslide investigation, landslide inventory and RS imagery interpretation, using the DEM data, ETM ＋ satellite image and feature dataset, and with the Weights of Evidence method, extracting and mapping statistical analysis of correlation were completed, and the out of landslide susceptibility evaluation factors and susceptibility division of the study area was carried
