摘　　要：为了解决单一依靠MapGIS软件编制航空地球物理调查成果图件或插图存在制图复杂、周期长等问题,采用MapGIS编图与矢量插图修编、整饰分离的技术路线,利用通用的矢量图形软件进行图件编辑、修改和整饰,以提高编绘质量与制图效率。研究中重点解决了MapGIS格式图件进行任意图幅范围的全矢量输出问题,保证了矢量图形编辑软件能够无损利用已有MapGIS图件的图形与渲染,实现地质、地球物理数据从地理信息系统到绘图系统的全保真转换。并且采用该编图方法编制了莽岭地区航空物探(磁、放)调查综合图件,结合具体的编图实例进一步阐述了编图思想、方法及具体的技术要求,实际编图效果表明,图件整体清晰、美观,能够准确地反映出该区的地球物理场特征,且编图效率有了较大的提高。Traditionally we compile airborne geophysical map only using MapGIS software, but the whole process of map compilation is complex and time consuming.To improve the efficiency and ensure the quality of airborne geophysical map or illustration map,we divide the whole process of airborne geophysical map compilation into two phases, the airborne geophysical map compilation by MapGIS software and the further decoration by general vector graphics editor. Then we focus on solving the problem of the conversion from the MapGIS format of any part of the map into the vector format and find the method of how to achieve full fidelity conversion of geophysical data from geographic information system to the vector graphics editor. Now the graphics and map decoration can be lossless opened and edited by any vector graphics editor. We have compiled the airborne geophysical map of Mangling （Qinling ） to further expound the ideas, methods and specific technical require-ments of the map compilation. The actual results show that the map is clear and beautiful,which reflects the characteristics of geophysical field , and the mapping efficiency has greatly improved.
