摘　　要：在利用DGSS系统进行1∶5万水系沉积物测量数据成图过程中,绘制单元素地球化学图(平面等值线图)时,由于布点等原因,图幅边部一般未能有效控制,往往造成图面完整性较差。利用扩边数据对图件进行扩边处理,配合由内图框制成的载剪框的使用,解决了利用原始数据绘制地球化学图不能完整充填图幅的问题,保证了地球化学图件的原始性、真实性与完整性。In the process of mapping 1:50,000 stream sediment survey data using DGSS system,the unit geochemical map(plane contour map)is drawn.Due to the distribution of points and other reasons,the edge of the map is not effectively controlled,often resulting in poor surface integrity.The problem that the geochemical map cannot be filled with the original data is solved and the primitiveness,authenticity and integrity of geochemical maps are guaranteed.
