自然地理野外实习虚拟仿真系统的建构与应用

Construction and application of virtual simulation system in physical geography field practice

针对高校自然地理野外实习的局限性,以东北师范大学自然地理野外实习线路为依据,构建了东北地区自然地理野外综合实习虚拟仿真系统.介绍了该系统的设计思路、实践过程以及特色与应用效果.该系统通过三维虚拟仿真技术和现代三维图形图像技术,将书本上宏观抽象的地理理论与现象鲜活地呈现,并提供三维交互体验.该系统的应用从根本上化解了传统自然地理野外实习的局限性,加强了学生对自然地理要素空间分异和自然地理过程变化的认识,提升了学生创新实践能力.同时,系统应用的推广也促进了虚拟仿真实践教学的发展,有利于国内优质教学资源的共享.

According to the limit of physical geography field practice,the virtual simulation system of physical geography field practicein northeast China was constructed,which was based on the field routes designed by Northeast Normal University.Introduced the design ideas,practice process,features and application effects of the virtual simulation system.The systemvividly displayed the abstract theories and phenomena of geographyin booksby 3D virtual simulation technology and modern 3D graphics and image technology,and provided 3D interactive experience.The application of the system fundamentally resolved the limitation of traditional physical geography field practice,strengthened understanding of spatial heterogeneity of physical geography components and changes of physical geography processes,and improved the ability of innovation and practice ability of undergraduate.In the meanwhile,the popularization of the virtual simulation system also promoted the development of virtual simulation practice teaching,and facilitated the sharing of high quality teaching resources.
