| 摘 要： | M资料经过定向滤波、主成分分析、线性增强和假彩色合成处理后,采用目视综合解译,获得线性影像综合解译图,经野外校核后编制完成庆元县15万断裂构造分布图。文章最后讨论了断裂分布与山地灾害空间分布的相关性,得出了在受深(大)断裂强烈影响的区域,山地灾害的空间分布与断裂交叉度和断裂密度具有一定的正相关,但不显著;火山构造作用引起的山地灾害斑块状分布较为明显。

| Abstract: | In order to enhance the linear image, the authors conducted directional filtering of the TM image and digital elevation model (DEM), and then used false color composite technique to produce a base map. Through interpretation of the base map and field verification, the distribution of fractures in Qingyuan County was mapped. The spatial correlation between fractures and mountain hazards was also investigated. The results show that if a region is affected intensely by deep faults, the positive correlation between mountain hazards and intersection density of fractures or density of fractures are existent but not notable. By contrast, the porphyritic distribution of mountain hazards caused by volcano-tectonic activity is quite obvious. |
