摘要
闽南沿海漳州地区长乐-诏安发育着不同方向的断裂构造,历来为我国地壳频繁运动的高发地区。因此,研究漳州地区断裂带及其活动性对该区域地质灾害的预报,工程的安全性评价具有重要意义。本文采用ALOS243波段与高分辨率波段融合的遥感图像为解译底图,提取线性构造和水系分布信息,应用分形学原理和方法对漳州地区遥感线性构造及水系进行定量研究。计算得出该区域总体线性构造及水系分维值分别为1.3518和1.2279。结果表明漳州地区活动断裂带展布结构复杂,构造活动性较强,未来有较高的地质灾害频发的可能性。
The Changle Zhaoan in Southern Fujian coastal area has developed faults in different directions. It has always been a high frequency area of frequent crustal movement in china. Therefore, it is of great significance to study the fault zone and its activity in Zhangzhou area to predict the geological disasters and to evaluate thesafety of the project. This paper adopts ALOS243 band and high resolution remote sensing image fusion band for interpretation map, extracting linear structure and water distribution information, quantitative analysis on the structure and the drainage area of Zhangzhou remote sensing linear application principle and method of fractal theory. The overall linear structure and fractal dimension of water system are 1.3518 and 1.2279 respectively. The results show that the active faults in Zhangzhou area have complex distribution structure and strong tectonic activity, so there is a t^ossibilitv of freauent occurrence of geological disasters in the tuture.
