摘要
地图既是地理信息的载体,又是传输地理信息的通道。专题地图所表示的内容是多方面的。其中用分级统计图法编制的单要素分析图,能否在不增加图内线划和注记的载负量的前提下表示更多的要素呢?当这些要素被确认为相关显著时,可以通过相应的图例配置,在同一幅图上完全表示出来。
This paper explores the possibility of presentation of more features without Increasing the map load of the linear graph and lettering. The author proves that as long as the features are recognized to be of strong correlation,they can be expressed on the same map under suitable arrangement of symbols. Examples of correlated features are given. Key points for the compilation are introduced and a map of cotrelated features of multi—variants is shown.
