浅谈现行世界地图上比例尺的变化

Scale Changes on the World Map

通过对我国现行世界地图上比例尺的差异化与地图投影的关系进行初步分析和研究,总结了比例尺在世界地图上的一些变化规律。结果表明,地图比例尺差异与比例尺的大小成反比、与地图投影变形成正比,比例尺差异化问题与地图选择的投影方式、地图的逐级缩编等因素有着直接的关系。

Based on our current World map on a scale of differentiation and map projection relations, this paper conducted a preliminary research, and summed up the scale variations on the world map. The results show that map scale is inversely proportional to the size of the difference with the scale and map projection distortion is proportional to the scale of the problem of differentiation selected projection map. The map progressively downsizing and other factors has a direct relationship.
