社会经济统计指标的地图符号标度与分析

利用平面、立体几何符号以及线性图案、立体块状和三角图表等定量地图符号,能较合理地在地图上标度社会经济的绝对、相对、密度、构成以及反映现象离散趋势等统计指标.虽然各类定量地图符号的标度方法均有优劣,但作者通过制图实践表明,只要合理利用,指标就能得到较科学的显示.

SCALE AND ANALYSIS OF MAP SYMBOLS OF SOCIAL ECONOMY STATICAL INDEXES

Statistical indexes of social economy: the absolute, relativity, density, composition and the trend reflecting dispersal phenomena, can be fairly rationally scaled on a map by making use of quantitative map symbols such as plane and solid geometry,linear pattern, solid block, triangle chart, and so on. Although various ways of scale of quantitative map symbols have their strong and weak points, through practice of map-making, the author finds that indexes Can be scientifically demonstrated when symbols are properly used.
