| 摘 要： | 本文依据陆地卫星多光谱扫描图像(Landsat-MSS),解译了营口地区的线性构造和环形构造。按其线性断裂的展布方向,划分了5个线性断裂构造带。金州断裂为本区的主要活动断裂,为西部中新生代以来接受补偿性堆积的坳陷断块区与东部长期遭受剥蚀的隆起斷块区的界线。两大断块区内,由活动断裂所围限的5个具有不同升降幅度的活动断块,影响了该区区域地壳稳定性。营口地区地震活动明显受北北东、北西向活动断裂的控制,前者对破坏性地震的空间分布和迁移起着控制作用,后者常与发震的具体部位密切相关,并主要发生在海城、盖县、熊岳三个地震活动带中。

| Abstract: | According to the images of Landsat-Multiple spectrum scanning,the linear structure and the circular structure in Yingkou area have been interpreted. Five linear structure zones are divided in the light of the extended direction. Jinzhou fault is the major active one in this area which is the boundary of the down-warped block region compensated by the accumu-lation since Mesozoic in the west with the up-warped block region eroded for a lang time in the east. Within the two lorge blocks the five active fault blocks, sur-rounded by active faults with different range of elevation and subsidence,control the stability of the regional crust. The seismic activity is controlled obviously by the active faults of NNE and NW. the former has the spatial distribution and the migration of the destructive earth-quake under control;the latter has a close relation with the exact earthquake loca-tion,and the earthquake mainly occur on three seismic activity belts in Haicheng, Gaixian, Xongyao. |
