利用遥感信息解译方法研究沈阳地区F5、F6断层的空间展布特征和活动性
|
摘要
以沈阳地区的LANDSAT 7 ETM+卫星数据和航空照片作为主要数据源,对卫星数据进行假彩色合成和图像融合,结合大比例尺地形图和实际地质调查对航空照片进行扫描、几何纠正处理,可以了解沈阳地区F5、F6断层的空间展布特征和活动性。结果表明,F5、F6断裂在其空间展布上均分别表现为一系列大致平行、呈斜列状排列分布的北东向断裂组,断裂具有分支复合形态,推断沿F5、F6断裂具有发生中等强度地震的危险性。
By analyzing the LANDSAT 7 ETM+ satellite remote sensing data and the aeronautical photographs,compounding the false-colour and mixing together of satellite images,and so on,scanning of and correcting geometrically the aeronautical photographs while analyzing large scale topographic maps and making practical geological investigations,we can recognize the spatial extension and activities of F5,F6 in the Shenyang area.the result shows that the F5,F6 faults are a series of NE trend fault group of parallel or inclined formed in spatial extension.These faults are compounding or separating in different sections.Above all,it is inferred that the F5,F6 faults are earthquake structures which can bring about mid-intensity earthquakes.
