中文摘要：

统计制图符号是用来表达统计数据类型的专题符号,是制图者理解数据与用图者认识数据之间信息与传递的重要桥梁。通过对统计制图符号的分类、空间布局和内部构成元素的深入分析,提出了一种利用空间布局构建统计制图符号的方法。阐述了空间布局约束下统计制图符号的形式化描述和组织方式,设计了统计制图符号生成的基本流程,依次构建了视觉变量、布局约束下的图元及统计制图符号。实验表明,该方法能够突破传统统计制图符号对数据依赖性强且构建复杂的局限,丰富统计制图符号的种类,具有一定的实际应用价值。

英文摘要：

Statistical cartographic symbol is used to express statistical data,which is the important bridge for data exploration and transfer between designer and user.By means of the thorough analysis on space layout,elements and classification of statistical cartographic symbol,puts forward a kind of building method of statistical cartographic symbols by using the space layout.Describes in detail the formalization description and organization of statistical cartographic symbol under the constraints of space layout,then designs the basic building flow.Afterwards,constructs visual variables,graphic element and statistical cartographic symbols in turn.Experimental results show that this method can break through the traditional limits of data dependency and building complexity,rich the kinds of statistical cartographic symbols,and has certain actual application value.
