【摘要】 遥感图像上的直线、弧线、折线(状)的成因与地质作用有关,其间接反映了地下断层的存在。在研究利用遥感图像提取地质线性构造的基础上,系统总结了线性构造遥感解译的原理、图像增强处理技术以及解译标志。以1990年蓬莱地区Landsat5TM图像为例,通过直方图均衡化、主成分分析、方向滤波、与DEM数据的复合等处理,最终解译出蓬莱地区NNE向主要断裂5条,其他次级断裂23条。更多还原

【Abstract】 Straight,arc-like and broken lines on the remote sensing images are mostly related to linear geological structures,and may indirectly indicate the existence of underground faults.In this study,taking the Penglai area as a case,the Landsat 5TM images of 1990 are used to extract linear structures based on the principles of remote sensing interpretation,image improvement technologies and interpretation signs.The techniques of histogram equalization,principal component analysis,filtering,and composite processing of DEM data are adopted to define those structures.5NNE major faults and23 other faults are found in the Penglai area as the results.更多还原
