| 摘 要： | 滑坡灾害遥感解译是遥感技术在滑坡灾害应用中的关键技术.研究表明,滑坡易发性和危险性区划图的误差主要来源于滑坡编目,其中大部分的误差则是源于滑坡编目时航卫片的解译,尤其是小比例尺航卫片的解译.从滑坡灾害解译、解译标志、解译过程等论述了滑坡灾害遥感解译,探讨了影响滑坡灾害遥感解译的不确定性因素,为减少滑坡编目和区划的误差提供参考.

| Abstract: | Remote sensing interpretation of landslide hazard is a key technique in application of remote sensing to landslide hazard.Research shows that most errors in landslide susceptibility and hazard zoning maps are originated from landslide inventory which imprecision is mainly from interpretation of aerial photograph in landslide inventory,especially for small-scale aerial pholograph.The remote sensing interpretation of landslide hazard were explained in view of interpretation designation and process.The uncertain factors influencing the remote sensing interpretation were explored to give a reference to reduction of landslide inventory and zoning errors. |
