摘　　要：研究将"3S"技术(RS、GIS、GPS)应用到机场地址勘察中,主要是采用现代化遥感技术,以最新遥感图像LANDSAT ETM(最高空间分辨率15 m),SPOT图像(2.5 m)和QUICKB IRD图像(0.61 m)等作为信息源,通过遥感图像数据融合、数字镶嵌和影像增强等数字处理,制作不同类型、不同波段和不同分辨率的正射遥感影像及正射影像地图,为机场工程地质勘察提供最佳图像资料。通过遥感图像增强处理、信息提取及GIS空间分析等,对研究区的地质构造,地质灾害等进行解译。并借助GPS进行野外现场调研,查明研究区地质构造的特征,尤其是隐伏断裂、活动性断裂的分布,以及岩溶漏斗、洼地等水文地质现象,为小哨机场工程地质勘察工作提供了基础资料。In this paper,'3S' technologies(RS,GIS,GPS) are applied to the airport geological survey,based on modern remote sensing technique.The up-to-date remote sensing image as LANDSAT,ETM image(spatial resolution 15m),SPOT image(spatial resolution 2.5m) and QUICKBIRD image(spatial resolution 0.61m),etc were taken as the information source,and through the digital processing such as remote sensing image data fusion,the numeral mosaics,image enhancement,The orth-image map of different types,different bands and different resolutions are produced and the best images for airport Engineering Geology reconnaissance can be produced.Based on the remote sensing image enhancement processing、information extraction and GIS spatial analysis,we can interpret the geological structure and geological disaster with the tools of GPS,The method can be applied in the field such as to do geological construction trait analysis,the analysis of distribution of hidden rupture and active rupture,furthermore the hydro geological phenomena analysis as Karst funnel and bill-along.The data it got above can be taken as the foundation for the project geological survey of XIAOSHAO airport.
