国家经济地图集基础地理框架的建立

以新世纪版《中华人民共和国国家经济地图集》的编研为背景，探讨了新世纪地学研究和测绘地理信息技术条件下经济地图集基础地理框架建立的若干问题。针对地图集的多尺度、多分辨率、多时态及内容的多样性等特点，通过对比与需求分析，重点探讨了地图集的地图投影、比例尺与分幅、地图定向及地理底图的设计与应用，并最终确定了地图集基础地理框架方案。

Establishment of Fundamental Geographic Framework of National Economic Atlas

In the background of the compilation and research on the National Economic Atlas of People’s Republic of China (New Century Edition), this paper delved into several problems in establishing the fundamental geographic framework of the economic atlas under the technological condition of surveying and mapping, and geo-information research of the new era.Focusing on the characteristics of multi-scale, multi-resolution, multi-temporal and diversity of the atlas,the paper discussed the map projection, map scale and subdivision, map orientation, and the design of geographical base maps through comparison and demand analysis, with which the fundamental geographic framework of the atlas was determined.
