摘　　要：我国于20世纪80年代以前编制的林相图等大多手工绘制的、无等高线的平面图,由于图纸变形的原因,林班和小班界线等无法直接转绘到地形图上,难于充分应用。为此采用扫描——几何精校正——矢量化——GIS支持下叠合地形图的方法进行转绘。结果表明,林班和小班界线与地形图匹配效果良好。Most forest maps printed before 1980s were plane map of manual drawing and had no any contours, therefore, they were difficult to transfer effectively the borderlines of the compartment and sub- compartment in them to the relief map,because of the paper distortion.This paper presented a method to transfer such maps,and it involved in map scanning,image geometric correcting, vectoring, and superposing with the relief map in GIS.The result indicated that the borderlines of the compartments and sub- compartments could be matched accurately with the relief map.
