摘要
遥感地质研究的定量分析能够给出客观、精确的数据和结论.利用ALOS高分辨率遥感影像,以昭通毛坪铅锌矿区线性体解译为基础,进行了线性体长度、方位、频度的常规统计分析,通过制作线性体方位玫瑰花图和等密度图,清晰展示了研究区线性体的优势方向和空间分布规律,得到了区内以北东(NE)向断裂构造为主的定量证据.并在此基础上,提出了线性体长度分级评价方法,探讨了更具地质意义的加权统计分析.
Quantitative analysis is a new hot spot of remote sensing geology, can give more objective and accuratedata and conclusions. Using ALOS high resolution remote sensing image, we made conventional statistic analysis of the lineaments＇ length,position and frequency as the foundation of lineaments interpretation on Maoping lead- zinc mine in Zhaotong area. Through the production of lineaments position rose diagram and the density figure, it clearly demonstrated the lineaments＇ advantage direction and spatial distribution law of the research area, and got the quantitative evidence that the priority position of the fracture structure in the area is NE-trending. And based on this,the paper puts forward an idea of grading evaluation, and probes into the weighted statistical analysis which has more geological significance.
