摘　　要： 依据心智表达的双重编码理论、地理的空间图形思维特点以及支持可视化知识探析需求,讨论地理知识可视化中知识图的定义与特点,并把地理知识图分为地理概念命题图与地理相似图解图,地理相似图解图又可分为逻辑拓扑相似图、空间结构相似图、变量关系相似图以及地理过程相似图。以黄土高原的小流域淤地坝系规划为案例,研究了支持坝系空间规划知识图中的概念命题图与相似图解图的形式、种类及其相互关系。 As a new field of visualization,knowledge visualization is to use maps,graphics,or images to construct and transfer insights and knowledge between at least two persons.In view of geovisualization,geographic diagram,geo-informatic Tupu,and visual analytics are cutting edge researches on visual and graphic representation and discovery of geographic knowledge.Thus,this paper focuses on the discussion of geographic knowledge visualization in terms of general knowledge visualization and geographic diagram.In the paper,the concept and characteristics of knowledge maps in geographic knowledge visualization are mainly explored according to the dual coding theory of representation of mental images,features of geospatial thinking,and need for supporting visual exploration of geo-knowledge.Geo-knowledge maps are defined as cognitive and abstract maps related to geo-problems,geographic spatiotemporal distribution,relationship of geographic factors,and so on.They should be fit for mental image representation and cognitive process,and helpful for human spatial memory,thinking and imagination to improve capability to handle geo-problems.Considering images like digital photos and remote sensing images,they all mimic the physical world in real life without any abstract contents of human thinking and reasoning.Therefore,this paper defines these mimic images as geo-information images which have differences from geo-knowledge maps that express human knowledge about the real world.Geo-knowledge maps have two kinds: weak and strong.Weak geo-knowledge maps have more objective,concrete,and mimic description,while strong maps are more subjective and abstract.Geo-knowledge maps have two classes: concept propositional maps and analogue diagrammatic maps.Concept propositional maps highlight verbal handling of geographic phenomena,while analogue diagrammatic maps represent geographic graphics and images.With regard to analogue diagrammatic maps,there are further four types: logic and topological similar maps,spatial structure similar maps,va
