丽江地区遥感影像线环结构特征与场地稳定性分析

The line-ring structures of remote sensing images and site stability analysis in Lijiang area

丽江地区活动性构造发育,地震发生频繁。以遥感影像线环结构理论论述了该区主要活动断裂和活动环块的遥感影像特征和地质地貌特征,并分析活动构造与场地稳定性的关系,进而划分出该区内易发震地区与相对稳定的地区。

The active structures are developed in Lijiang area and tectonic earthquakes then are happened frequently. The line and ring structures on remote sensing images are interpreted in this paper, and then the characteristics of important active faults and rings in images, and the geologic and geomorphologic characteristics of the areas are all described. The areas that earthquake will be apt to happen are plotted out from the background.
