利用遥感(RS)、全球定位系统(GPS)、地理信息系统(GIS)等高新技术的有机配合可以快速高效地完成环境条件恶劣地区的资源地质调查工作。以宁夏碱沟山地区煤田地质调查为例 ,介绍了“3S”技术的应用情况。即应用法国SPOT卫星图像对地质、地貌等要素进行综合解译、对比和分析 ;应用全球定位系统对地质、地形地貌等要素进行野外控点 ;应用地理信息系统对调查成果进行综合分析、编辑和制图。总结了应用“3S”技术进行资源调查的工作方法和程序。“3S”技术进行资源地质调查具有快速高效、低成本的优势 ,值得在今后的国土资源调查中推广和应用。
The use of high-tech organic combination of remote sensing (RS), global positioning system (GPS), geographic information system (GIS) and so on can quickly and efficiently complete the geological survey of resources in harsh environmental conditions. Taking the geological survey of coalfields in the alkali mountainous area of Ningxia as an example, the application of “3S” technology is introduced. Namely the application of the French SPOT satellite imagery to synthetically interpret, compare and analyze the geology and geomorphology and other elements; the application of global positioning system to the field control of geology, topography and other elements; the application of geographic information system to conduct a comprehensive analysis of the survey results, editing and mapping. The working methods and procedures for resource investigation using “3S” technology are summarized. “3S” technology for resource geology survey has the advantages of rapid and efficient, low cost, it is worth in the future land resources survey to promote and apply.
