摘　　要：随着专题地图的广泛应用,地图的自动布局与快速输出也受到了更多的关注。作者通过分析总结专题地图的布局原则,归纳了常见的地图布局方式,设计了适用于专题地图快速输出的自动布局过程。本文重点阐述了主区形态分析的过程与方法,包括边界数据的压缩、边界最小外接矩形的计算等。通过反复实验,证明该主区形态分析方法科学有效,得出的布局方式基本合理,有利于专题地图快速输出的实现。With more and more extensive application of thematic maps,the automatic layout and fast output of maps have drawn more attention.The authors analyzed and summed up the layout principles of thematic maps,generalized the common map layout,designed the automatic layout process applicable to the fast output of thematic maps.The article focused on the process and methods of the morphological analysis of the main area,including boundary data compression,calculation of the minimum bounding rectangle,etc.Through repeated experiments,the authors proved that the morphological analysis of the main area was scientific and effective,the layout was basically rational,which would be conducive to the implementation of the thematic maps fast output.
