摘　　要：地图注记是一种广义的地图符号,用以配合其它符号说明事物的名称、数量、质量特征,是地图中不可缺少的重要内容。注记位置配置的合理与否在很大程度上影响着地图的易读性,而注记配置速度的快慢也直接影响了地图的显示速度。介绍了一种对于地图注记的自动配置算法,对于在电子地图中实现注记自动配置显示具有参考意义。The annotation of maps is a kind of sign of broad sense, it cooperates with other kinds of sign to explain something＇s name, amount, quality characteristic, and it is an important content which is indispensability of the map. The rationality of the annotation＇s allocation greatly influences the legibility of the map, and the speed of the annotation＇s allocation also directly influences the display speed of the map. This text introduced a kind of automatic allocating arithmetic of the maps＇ annotation, and it has some referenced meaning to the realization of the automatic allocation of the maps＇ annotation in the electronics maps.
