活动断裂带中遥感数字图像处理技术──以鲜水河活动断裂带为例

断裂活动往往引起地貌景观和水系格局等的变化。在遥感图像上，这些细微的变化通过颜色以及空间纹理特征以直接或间接的方式表现出来。运用数字图像处理技术，对鲜水河地区ＴＭ图像进行了参量统计、增强变换等处理，还进行了水系特征、纹理特征、波谱分析以及含水性信息等专题信息的提取研究，掌握了一套实用的方法

THE TECHNIQUE OF TM DATA IMAGE PROCESSING IN THE INVESTIGATION OF ACTIVE FAULT ZONE ──XIANSHUIHE ACTIVE FAULT ZONE AS AN EXAMPLE

Fault movements tend to result in the variation of landscape and water system regime, which can be displayed directly or indirectly on TM images through color and spatial texture features. Data image processing techniques were used to extract and analyze the water system features,texture features and the water-bearing information of Xianshuihe region. Detailed study was made on the geometric morphological features and tectonic geological background of Xianshuihe active fault zone.
