摘要
地理学是一门研究各种地理要素的时空分布、演化过程,以及相互作用机制的综合性学科。随着现实世界从二元空间向三元世界的演进,对地理信息内涵的理解、表达和挖掘亟待进一步加深与扩展。现有以"位置+几何+属性"的地理信息表达模式难以支撑各种地理要素及其规律的表达。本文从地理学视角出发,立足三元世界理念,梳理了信息要素及其转变成地理信息的过程,形成了以时间、地点、人物、事物、事件、现象和场景"七要素"的信息表达体系,并从地理语义、空间位置、几何形态、属性特性、要素关系、演化过程、作用机制7个地理维度上对其进行解读。实现了地理学视角下对地理信息内涵的全方位分类和描述,为面向地理学综合集成研究的地理信息多维描述与计算分析提供理论支撑。
Geography is a comprehensive discipline that studies the spatial-temporal pattern, evolution process,and interaction mechanism of various geographic elements. With the evolution of the real world from binary space to the ternary world, it is urgent to deepen and expand the understanding, expression, and mining of geographic information connotation. The existing geographic information expression model of "location +geometry + attributes" is difficult to support the expression of various geographic elements and their laws. From the perspective of geography, based on the concept of the ternary world, we sort out the information elements and the process of their transformation into geographical information and form an information expression system with the "seven elements" of time, place, character, object, event, phenomenon, and scene, and from the geography "seven dimensions" perspective of semantic, spatial location, geometric structure, attribute,interrelationship, evolution process, mechanism of effect to interpret. It realizes the all-around classification and description of the connotation of geographic information from the perspective of geography and provides theoretical support for the multidimensional description and computational analysis of geographic information for comprehensive and integrated research in geography.
