依据特普费尔公式和申农公式,按照综合方法对图形进行了分类,对“应该如何综合”和“综合到什么程度合适”等问题进行了探讨。不但得出在原图中需要舍弃、修改和保留的三类图形对象应占比例,而且求得综合后新图中属于采用和修改过的两类图形对象应该保持的比例,对地图综合、综合检验与工作量计算等都具有指导性意义。
This paper classifies the graphics based on synthetic method according to F. 'fopfer formula anddiscusses such problems as "how to do the synthesis " and "what kind of degree of synthesis is suitable",etc.. Not only is the proportion of objects among rejection, modification and acceptance in old maps neededbut also the proportion of objects between acceptance and modification in new map is given. The result hassome significance to cartographic synthesis, synthetic check, and workload calculation, etc.
