Resümee

The human geographic environment is a comprehensive environment formed by the interaction of human activities and the geographic environment, which is complex and highly vulnerable. Introducing the digital twin method to build a new framework of research on human geography issues has great disciplinary importance and application value because this framework has the characteristics of driving the virtual according to the real, controlling the real according to the virtual, and the coordinated evolution of the virtual and the real. It also helps avoid disturbing the real environment, explores complex problems in depth, and optimizes the control scheme of real geographical problems. Based on the review of relative research in China and abroad, a conceptual model of the digital twin human geographic environment is proposed, and its systematic connotation is elaborated. The major components of this system include the real human geographic environment, the virtual human geographic environment, and the information interaction between them. Through the digital twin construction and simulation of the geographic environment, human activities as well as human-nature interaction, the virtual and real synergy, complementary advantages, and coevolution between the virtual and the real environment can be realized. Furthermore, a technical framework with bilateral technology roadmap for the implementation of digital twin human geographic environments is proposed. One route is to complete the comprehensive perception and twin reproduction of the real human geographic environment through digital accurate mapping to the virtual geography environment, and the other route is to achieve intelligent feedback of the virtual human geographic environment and its manipulation on the real human geographic environment through multichannel virtual-real interaction. On the basis of the above, a hierarchical construction scheme of the digital twin human geographic environment platform, which covers five sub platforms, namely, collaborative monitoring and environmental awareness platform, multimodal full-scale database, intelligent modeling and simulation technology integration, high-performance spatiotemporal computing engine, and cross-domain knowledge application for decision making is designed. Supported by the Nanchang Subcenter of the UNESCO International Natural and Cultural Heritage Space Technology Center, the digital twin of Jiangxi Bailudong Academy, the education base of Chinese Confucian culture, is taken as a typical case to demonstrate the construction method, main function, and result form of the digital twin human geographic environment. The conclusions are drawn from three perspectives: (1) The digital twin human geographic environment should be taken as a creative method for the exploratory learning of human geography. (2) The digital twin human geographic environment is currently the best way to build a geographic metaverse with human activities. (3) The virtual geographic environment can provide theoretical basis for the construction of the digital twin human geographic environment. Lastly, the purpose of this paper is to throw bricks and spark jade to arouse scholars’ thinking on the research of coupling digital twins and human geographic environment, and to promote the sustainable development of human geography jointly.
