摘　　要：地理国情普查成果图集制作是地理国情普查成果重要应用之一。本研究以湖南省宁远县为例,根据GIS无级比例尺的思想,利用WJ-Ⅲ地图工作站,建立缩编规则库,实现了宁远县地理国情普查数据从1:10000到1:50000,1:100000,1:150000的无级自动化缩编制图。并采用面积变化对比法对缩编结果进行验证,缩编制图后各类面积变化量均没有超过10%,制图效果良好。研究成果进一步肯定了利用计算机制图的可行性,可为地理国情普查数据向其他比例尺的缩编制图工作提供参考价值。The production of atlas of geographic national census results is one of the important applications of geographical national census results. Taking Ningyuan County in Hunan Province as an example, this paper uses the Map Workstation of WJ-Ⅲ to establish a map down rule base according to the concept of GIS without scale, and realizes the stepless automation reduced drawing of geographic national survey data of Ningyuan County from 1：10000 to 1：50000,1：100000 and 1：150000. The comparison of area changes was used to verify the drawdown results. After the drawdown, the area change amount did not exceed 10% and the mapping effect was good. The research results further confirmed the feasibility of using computer graphics to provide reference value for the census data of geographical national conditions to other scales.
