FRACTAL RESEARCH OF REMOTE SENSING LINEAR FAULTS IN SHANDONG PENINSULA
-
摘要: 利用早期地表人为破坏程度较低的遥感数据,通过各种线性构造遥感图像处理方法,结合地质地形资料解译出山东半岛断裂。分形理论作为定量分析复杂自相似图形的工具被应用在最终遥感解译成果的分形研究中,通过箱型覆盖法,分别求得研究区内21个单元格的分维值,并绘制分维值等值线图。研究表明山东半岛遥感解译断裂分维值为1.09~1.78,东部以北东、北北东向构造为主,西南以北西、北北西向构造为主,且这两组断裂在空间上以互补形式存在,反映它们相互制约的性质。Abstract: Use the early remote sensing images, which have not been seriously damaged, after processed by some methods for the linear images, in combination of geological and topographic data, we made interpretation of the linear structures on the Shandong Peninsula. As an efficient tool for quantitative analysis of complex self-similar graphs, the fractal theory is used in the final interpretation of remote sensing results. The fractal dimension values of 21 cell zone are calculated with the box-counting method, and the fractal dimension isograms are derived. The research results show that the fractal dimension values of the faults on the Shandong Peninsula vary from 1.09 to 1.78 with the main structural direction in NE-trending and NNE-trending in the eastern and NW-trending and NNW-trending in the southwest of the study area; and the two groups of faults are complementary each other on the space.
