摘要 提出虚拟地理环境概念 ,并讨论其特征。虚拟地理环境 ,是包括作为主体的化身人类社会以及围绕该主体存在的一切客观环境 ,其中的化身人类是表示现实世界中的人与虚拟世界中的化身相结合后的集合整体。虚拟地理环境结构由地理位置层面、内表达数据层面、外表达境象层面、单主体感知认知层面和互主体社会层面组成 ,它的孕育演化包括虚拟群落社会、虚拟村落社会和虚拟城市社会 3个阶段。最后讨论了地学虚拟环境与虚拟地理环境 ,以及虚拟地理环境和现实地理环境的相互关系。 This paper addresses the concept and characteristics of virtual geographic environments (VGE). VGE are environments pertaining to the relationship between avatar-based humans and 3-D virtual worlds . Avatar-based humans are defined as a combination of humans in the real world with 3-D avatars in 3-D virtual worlds. Five types of space, namely Internet space, data space, 3-D graphical space, personal perceptual and cognitive space, and social space are used to explore the characteristics of VGE. The evolution of VGE is illuminated via three stages: virtual crowds, virtual villages, and virtual cities. The paper finally discusses the relationships between VGE and geo-referenced virtual environments and the physical (real) geographic environments.
