摘　　要：通过分析统计专题地图图例符号的分类和特点,提出了图例元的概念。在对图例元分类及形式化描述的基础上,构建了基于图例元的统计专题地图图例符号自动生成模型;设计并实现了统计专题地图图例的自动生成模块,最终应用到统计专题地图的制作过程中。结果表明,该模型可以生成各类统计专题地图图例符号,具有一定的拓展性,促进了统计专题地图制图的自动化。By analyzing the classification and characteristics of the statistical thematic map legend symbols, the paper puts forward the concept of the legend element, and on the basis of the legend element classification and formalization,the statistical thematic map autogeneration model is constructed, the statistical thematic map legend automatic generation module is designed and accomplished, and finally is applied to the production process of statistical thematic map. The results show that, the model can generate different statistical thematic map legend symbol,has certain expansibility, and promotes the automation of statistic thematic cartography.
