摘要
本文采用DEM数据与SPOT数据融合后的卫片,对长春市区隐伏断裂进行了遥感解译。解译标志包括(1)色调异常面,色调异常带;(2)平直伸展的地形陡坎,丘陵和台地的平直界限,切割岗脊的平直界限,切割岗脊的线性负地形,山体及沟谷的扭动;(3)格状水系,水系沟谷流向突然转变,分水岭两侧水系不对称。根据这些遥感解译标志,解译出长春市区4条东西向断裂,11条北东向断裂,11条北西向断裂,11条近南北向断裂。
Faulted structure in Changchun city are interpreted with syncretizing satellite photograph of DEM and SPOT date. Interpretation keys of faults include （1） abnormity plane and belt of tinge; （2） straight extending scarp of landform, straight margin of hill and mesa, straight margin and negative linearity landform cutting hummocky ridge; （3） clathrate water system, abruptly changing flow direction of water system cleuch, asymmetry faults, eleven NE faults, eleven NW faults and of water system on both sides of watershed. Four EW eleven SN faults are interpreted on the basis of those interpretation keys of remote sensing.
