麻城—团风断裂带分段活动特征遥感调查
|
摘要
遥感图像可以从宏观上反映活动断裂的空间展布规律和构造特征。在区域地质特征分析基础上,采用数据预处理、信息增强和数据融合等图像处理方法,提高了遥感图像的清晰度和可解译程度;根据遥感图像光谱特征和几何特征建立断裂构造带解译标志,进行断裂构造带及其活动性解译;结合野外调查,对麻城—团风断裂带进行了宏观分析和分段性活动的初步研究。研究结果表明:麻城—团风断裂带可按其控制力强弱分为北、中、南3段,北段图像线性特征明显,断裂解译标志显著;中段断裂控制力减弱,图像线性特征较模糊;南段为隐伏断裂。遥感技术在麻城—团风断裂带活动性调查中发挥了重要作用,特别是高分辨率遥感图像和遥感图像处理技术的应用不仅可以加快调查进度,还能为实地调查提供指导信息,从而显著提高调查效率与精度。
Remote sensing image can reflect distribution rules and structural features of active faults exhibition space from the macro. Based on regional geological study,the authors used data preprocessing,information enhancement and data fusion to improve the degree of clarity and interpretation of remote sensing images. The interpretation keys of the fault zone were established based on the spectral characteristics and geometric flag of the remote sensing images,and the interpretation of the faults and their activities was carried out. Combined with field investigation,the macro analysis and segmentation activity study of Macheng ― Tuanfeng fault were carried out.The results show that Macheng-Tuanfeng fault zone can be divided into northern,middle and southern sections according to the intensity of the control force. The linear characteristics of the northern section are apparent in the image,and the interpretation key of the fault is remarkable. The fracture control force of the middle section is weak,whereas the linear characteristics of the image are fuzzy. The southern section is a buried fault. Remote sensing technology plays a very important role in the survey of the activity of Macheng ― Tuanfeng fault zone; the application of high resolution remote sensing imagery and remote sensing image processing technology, in particular,can not only speed up the progress of the investigation but also provide guiding information for the field survey,so as to improve the survey efficiency and accuracy.
