摘要
断裂构造是地球应力的外部表现。断裂构造的识别对于地震、滑坡、泥石流等地质灾害的预测,以及矿产资源的勘探、开发等具有重要意义。利用ALOS影像,结合地形图,通过分析研究区内地形、地貌构造及水系特征等,建立了德兴地区断裂构造的遥感解译标志。通过实地验证,该研究区内存在断裂构造100余条,北西方向断裂为区域性断裂。
Faults are the concentrated expression of terrestrial deep stress. Recognition and interpretation of faults are important for mitigating natural calamity through disaster forecast, such as landslide, debris flow and other disasters. It is also significant for mineral exploring. In this study, ALOS remote sensing （RS） images were introduced. Interp- etatiom of construeitve fault fractures were conducted through a detailed study of terrain and landform features on RS image. In Dexing area, there are more than 100 constructive fractures. NW-striking facults are territorial faults.
