| 摘 要： | 以南水北调中线工程核心水源区为例，利用中、高分辨率光学影像、雷达影像和数字高程模型等多源遥感数据，开展断裂构造提取方法研究。综合利用多源遥感数据的对地穿透能力、光谱信息和空间几何信息，进行图像增强、融合处理和三维地形分析，突出目标区断裂构造的影像标志。通过多源遥感解译，结合现场调查验证，初步查明目标区内3条主要断裂的几何展布信息，为该区的活断层探测和地震危险性评价提供参考。

| Abstract: | In this paper, multi-source remote sensing data are used to study the method of faults extraction, taking the central water source area of middle route of south-to-north water diversion project as an example. The multi-source remote sensing data includes medium-resolution optical images, high-resolution optical images, SAR images and DEM. In order to make full use of the penetration capability, spectral information and spatial geometry of the multi-source remote sensing data, the image enhancement, image fusion and three-dimensional terrain analysis, etc. are used to highlight the image flag of the faults. By the interpretation of multi-source remote sensing data and the field survey, the geometric distribution of the three major faults in the target zone are identified. It provides the reference for active fault detection and seismic hazard assessment in this area. |
