遥感图像具有宏观、真实和构造迹线清晰的特征,所以通过遥感图像解译来研究地震地质是一种十分有效的方法。本文试图应用遥感图像目视解译结果来研究吐-哈盆地的活动构造特征,并且讨论了该地区的地震活动规律。在本研究中,一方面,在几何纠正和镶嵌后,把4、7、1波段与第8波段融合,获得一幅15m分辨率的彩色图像,在此基础上进行一些有效的图像处理,如增强和特征提取,通过相关处理,增强了线性特征;另一方面通过DEM分析图像,产生三维效果。这两方面工作对研究地质构造和活动断裂带都是非常有用的。本文用纹理分析和DEM 分析的方法,提取了该地区的线性构造特征,使得我们对双背驮结构有了新的认识,并且对该地区的特殊结构与地震活动规律的相关性做了一些分析。
Remote sensing images have clear macroscopic, real and tectonic traces, so it is a very effective method to study seismic geology through remote sensing image interpretation. This paper tries to use the remote sensing images to interpret the results visually to study the tectonic features of the Tuoha basin and discuss the law of seismic activity in the area. In the present study, on the one hand, after geometric correction and mosaic, the 4,7,1 band and the 8th band are merged to obtain a color image with a resolution of 15m, on the basis of which some effective image processing such as Enhancement and feature extraction, through the relevant processing, enhance the linear features; the other hand through the DEM analysis of the image, resulting in three-dimensional effect. These two aspects of work are very useful for the study of geological structures and active fault zones. In this paper, we use texture analysis and DEM analysis to extract the linear tectonic features of the area, so that we can get a new understanding of the double-piggyback structure and do some analysis on the correlation between the special structure and seismicity in this area. .
