中文摘要：

目前大比例尺地质灾害图件往往将滑坡体的边界线与滑坡后壁的边界线相混淆，使制图者与读图者之间的交流受到了影响。本文对大比例尺滑坡灾害制图方法进行了探讨，希望在滑坡灾害制图时将滑坡体与滑坡后壁明确分开。

英文摘要：

The boundaries of landslide body and landslide back wall are often confused in the large-scale geological hazard map. As a result, persons who make drawings can not communicate very well with those who interpret drawings. Therefore, in this paper the largescale landslide mapping method is discussed and we hope that the landslide body and landslide back wall should be divided clearly.
