本文以地球系统科学、地球信息科学和现代地图学的理论、方法和技术为指导,系统地研究和建立了面向地理特征的制图综合的指标体系和知识法则,并进行了实例应用分析。研究方法是采用地学分析和归纳、地图分析、专家咨询、ＧＩＳ和遥感空间分析等方法来总结、提炼和建立制图综合的指标体系和知识法则。指标类型包括数据指标、文字说明指标、图形指标３种,共分数据库概括(即语义概括)和地图可视化概括(即图形概括)两类。知识法则在横向由几何性知识、结构性知识、过程性知识构成,在纵向按照地物的地理特征描述性知识、操作项选择知识规则、算法选择知识规则、面向专门地理要素和制图综合知识规则、面向区域制图综合的知识规则等过程和方面来组织和分类。在知识库中则按照概括条件、概括行为和概括要求(或概括水平)３个变量来组织,形成三维坐标关系的知识法则内部体系。在实例分析中阐述了珠江三角洲经济区的交通网络图的制图综合过程和结果。

This paper expounded the author’s research on the index system and knowledge rules for Geographic - Feature - Oriented Generalization, and an example of its application. The research approach is the integration of geo-science analysis & conclusion, map analysis, expert consulting, as well as GIS &. RS spatial analysis method, to extract, conclude and build them. The index system include three types as data, literal and graphic index , and on the other hand grouped by database generalization index and map visualization index. The knowledge rules include, in crosswise, geometric, structure and procedure knowledge, and in lengthways, the knowledge of geographic feature description, operator selection, algorithm selection, as well as specific geo-object oriented and specific region oriented knowledge. In the knowledge base, these knowledge rules are organized by three dimension of variables as generalization condition, generalization scope/level, and generalization actions. The example is the generalization of The Map of Transportation Network in Zhujiang Delta Economic Zone.
