【摘要】 采用SPOT-5与Landsat-7卫星影像相结合的遥感技术,对珠海市及其外围地区的断裂构造分布情况开展了遥感地质调查,经过图像处理、图像分析、地质解译和实地查证,共确定出各类断裂构造69条。依照其对地面稳定性可能的影响分为5种不同的危害程度类型,据此,确定出一级影响断裂9条,二级影响断裂18条,三级影响断裂16条,四级影响断裂5条,五级影响断裂21条,为珠海城市安全发展提供了新的科学依据。更多还原

【Abstract】 Many earthquake hazards caused by fracturing occurred in history because of the complex fault system in Zhuhai.A remote sensing geological survey by using SPOT-5 and Landsat-7 satellite images for the distribution of the fault structures in urban area and its surrounding area of Zhuhai was carried out in 2006.About 69 faults were delineated by means of image processing,analysis,geological interpretation and field investigation.According to possible impact on ground stability,they are classified into five levels of risk,which include 9 faults as first level,18 faults second level,16 faults third level,5 faults fourth level and 21 faults fifth level.This study may provide new scientific and technologic basis for safe development of Zhuhai.更多还原
