摘　　要：地理知识形式化是地理专家系统中的瓶颈问题 ,本文探讨了地理知识形式化的基础、地理圈层与地理系统分解为因子层数据的可能性、圈层与系统之间的公因子、地理数据与地理知识的相互转化、地理知识的等级与分等定级、地理知识的编码等问题。Formalization of geographical knowledge is the bottleneck of geographical expert system.This paper discusses the basis of geographical knowledge formalization,which is analyzed factor data from geo-sphere and geo-system.The paper also discusses common factors between geo-sphere and geo-system,translation between geographical knowledge and geographical data and geographical knowledge's grading and coding,etc.There are eight parts as follows:(1)Basis of geographical knowledge formalization;(2)Analyzed factor data from geo-sphere;(3)Analyzed factor data from geo-system;(4)Common factors between geo-sphere and geo-system;(5)Translation between geographical knowledge and geographical data;(6)Geographical knowledge grading;(7)Geographical knowledge coding model;(8)Commix information coding model..
