摘要
该文结合研究区的地质条件和人文经济活动状况,利用高分一号和高分二号卫星影像数据,对研究区内部的地质灾害进行遥感解译。首先,从地形地貌、影像特征等方面建立研究区的地质灾害解译标志,解译区域上地质灾害;然后,将遥感解译初步成果,提交给野外实地调查人员用于野外调查验证,重点解译崩塌、滑坡等的形态,规模,危害范围;利用DEM提取坡度大于50°的范围,以提高崩塌解译识别的准确率。该文可以为类似工程提供参考和帮助。
Combined with the geological conditions and cultural and economic activities situation in the study area,the remote sensing interpretation of geological hazards in the study area is carried out by using the satellite imagery data of GF-1 and GF-2. First,the interpretation marks of geological disasters in the study area is built from the aspects of topography,geomorphology and image features,and the geological disasters in the area is interpreted; Then,the preliminary results by remote sensing interpretation is provided to the field investigator for field investigation and verification,and the form,scale,and damage range of the collapse and landslides are as the focus interpretation; The range of slope more than 50° is extracted by using DEM,in order to improve the accuracy of collapse interpretation recognition. This paper can provide reference and help for similar engineerings.
