摘　　要：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 appearance of high-accuracy satellite remote sensing image, it has been come true to carry out engineering geology exploration using remote sensing. By using QuickBird, SPOT image, this paper first interprets and analyzes unfavorable geological conditions （mainly karst） of the research area which is based on remote sensing image digital processing and related geological knowledge, it then obtains interpreted chart, and discusses the distributed rule, the causes of formation and it developing trend. Such method provides feasible engineering geology appraisal, it also has a good reference to engineering construction in karst areas.
