随着高分辨率卫星遥感图像的出现,应用遥感技术在小范围内进行大比例尺的工程地质勘查已成为现实。本文以QuickBird、SPOT图像为主要信息源,在遥感图像数字处理的基础上,结合基于地学知识的图像识别和解译技术,对研究区不良地质现象(主要为岩溶)进行判译及统计分析,最后形成岩溶漏斗解译成果图,并探讨了其分布规律、形成原因及发展趋势,为机场建设提供了可行性的工程地质评价,同时对岩溶地区工程建设具有很好的借鉴意义。
With the advent of high-resolution satellite remote sensing images, the application of remote sensing technology to large-scale engineering geological surveys in small areas has become a reality. In this paper, QuickBird and SPOT images are taken as the main source of information. Based on the digital image processing of remote sensing images, combined with the technology of image recognition and interpretation based on geo-knowledge, the paper analyzes and decodes the adverse geological phenomena (mainly karst) Finally, the karst funnel interpretation result map is formed, and its distribution, formation reason and development trend are discussed, which provides feasible engineering geological evaluation for airport construction and good reference for engineering construction in karst areas.
