详细精确的滑坡编目是地震滑坡危险性分析工作中必不可少的一部分。理想的编目要满足如下条件:覆盖整个地震影响区;应包含所有可调查到的滑坡,滑坡的最小长度应小至1～5m左右;编目中的滑坡位置也必须准确,应使用能够反应它们真实的平面形状的区要素来表征。符合上述要求的滑坡编目可以用来进行地震滑坡危险性分析和其他的定量分析研究。详细的地震滑坡编目可以追溯到1960年代初的航空摄影技术的出现与应用。近年来,随着空间技术科学的进步,高分辨率卫星影像获取成为可能,从而使得除最小的滑坡之外可以识别并绘出所有由地震事件触发的滑坡。得益于遥感技术的这种可以观测到地球任何地方的能力,我们可以获取到任何大量地震滑坡发生区域的遥感影像。然而,随着高分辨率遥感影像时代的到来,地震滑坡编目数据不完整也成为当前研究中的一个普遍存在的问题。
Detailed and accurate landslide cataloging is an indispensable part of the earthquake landslide risk analysis. Ideally, cataloging should satisfy the following conditions: covering the whole area affected by the earthquake; including all landslides that can be investigated; the minimum length of the landslide should be as small as 1 ~ 5m; the location of landslides in cataloging must also be accurate; The shape of the area elements to characterize. The landslide inventory meeting the above requirements can be used to carry out the landslide risk analysis and other quantitative analysis studies. A detailed catalog of seismic landslides dates back to the advent and application of aerial photography in the early 1960s. In recent years, with advances in space science and technology, high-resolution satellite image acquisition has made it possible to identify and map all landslides triggered by seismic events in addition to the smallest landslide. Thanks to this capability of remote sensing, which can be observed anywhere on Earth, we can get remote sensing images of any large area of landslide occurrence. However, with the advent of high-resolution remote sensing images, the catalog data of earthquake landslides has become a ubiquitous problem in current research.
