遥感技术在江西永丰县地质灾害调查中的应用

Remote sensing technology investigation of geological disasters in Yongfeng county Jiangxi province

本文论述了遥感技术在江西永丰县1∶50000地质灾害调查中的应用,表明地质灾害遥感调查应用的效果。文中简述了遥感解译的工作方法,通过MAPGIS平台进行图像处理,建立了滑坡、崩塌、泥石流、地面塌陷等地质灾害的解译标志。在Google earth高清影像覆盖区,可对小型地质灾害进行精确的解译;通过相关的图像处理技术,对断裂构造,岩溶盆地也可进行相关解译;最后提出了地面野外调查的相关建议。实践证明,遥感解译可对地质灾害地面调查起互补验证作用。

This paper discussed the application of remote sensing technology in geological hazard survey using1： 50000 scale in Yongfeng County Jiangxi province,showed that the application effect in the remote sensing geological disaster investigation. In this paper,the work method of interpretation of remote sensing is discussed,and using MAPGIS platform for image processing,establishes the interpretation signs of landslide,collapse,debris flow,ground subsidence and other geological disasters. In the area covered by the GOOGLE earth highdefinition image, accurate interpretation of the small geologic disaster is possible; And with the image processing technology through the relevant graph,the faults,karst basin can also be associated interpretation.Finally,provides some suggestions of ground investigation. Practice has proved that the remote sensing interpretation can be complementation effect on ground geological hazard investigation.
