【摘要】 随着Internet的发展,以VRML为代表的基于WWW的虚拟现实建模技术正在日益受到广泛的重视。在对近10年西藏自治区山南地区草地资源的时空变化状况进行研究的基础上,基于VRML、遥感等技术构建了山南地区虚拟草地模型,以形象、直观的方式对山南地区草地退化过程进行了多维动态模拟,为进一步研究山南地区草地资源的时空变化规律及其机理提供了技术支持。更多还原

【Abstract】 Accompanied with the development of Internet,more emphasize has been put on the VirtualReality simulation,which is based on the web technology.In this study,the Temporal-Spatial change ofthe grass resources of Shannan Prefecture in Tibet during the past l0 years was used to construct the modelby using the technology of VRML and remote sense.We also simulated the process of the grassland de-generation,which will be useful for future research on the pattern and mechanism of grassland resourceschanging.更多还原
