| 摘 要： | 研究工作选择扬子地台西南缘冕宁-西昌一带为目标区,以高分辨率的TM遥感数据为基础资料,统计了波段之间的相关系数和图像信息量,根据一定的指标确定了图像的最佳波段组合,通过各种图像增强与融合方法,提高了图像清晰度.在图像处理的基础上,根据各种判读标志解译出冕宁-西昌一带断裂,发现该区EW向断裂发育时间最早,断裂主为SN向和NNE向.

| Abstract: | The Mianning-Xichang area in the southwest margin of Yangtze platform was chosen as the study area with TM image data as the basic information. Correlative coefficient for each band and their information volume statistics were carried out. According to a certain criteria is determined the optimum band-combined image. The image definition is improved by various enhancements and fusions. The image interpretation locates faults in Mianning-Xichang area and reveals the EW-trending faults are the first developed and SN and NNE- trending ones are the dominant. |
