摘要
地理信息是地理信息系统的主体,其特质决定了世界上出现的第一个大型信息系统是地理信息系统。地理信息系统是在积累和传承地理信息科学创新进步的基础上,经历漫长的过程产生和发展,既是历史的产物,也是现代的结晶。目前,地理信息系统随着计算机技术、网络技术、仿真技术的进步处于迅速优化阶段,是构建数字地球不可或缺的支撑技术。探讨和了解地理信息系统产生和发展轨迹有助于正确确定数字地球(山地)构建的阶段性目标。“数字地球”概念的提出迅速在世界范围内引起强烈反响,我国政府和科技界高度重视。“数字山地”是“数字地球”重要的有机组成部分。我国是多山国家,构建数字山地意义重大,势在必行。阐述了构建数字山地的必要性和可行性,介绍和讨论了构建数字山地的14项研究内容和构建数字山地的科学体系以及关键支撑技术。同时指出,数字山地的构建是一项复杂的系统工程,研究与应用并重,机遇与挑战共存,任重而道远。
The geographical information is the main body of the geographical information system （GIS）, and its special characteristics decide that the first large-scale system appears in the world is the geographical information system. The naissance and development of geographical information system has experienced a long process of accumulation and inheritance of innovation and progress of geographical information science, so that GIS is not only historical product, but also modem crystallization. At present, the geographical information system is at the rapid optimized stage along with the progress the computer technology, the network technology and the simulation technology, and becomes an indispensable strut technology of the Digital Earth, The discussion and the understanding of the naissance and developing trace of GIS will benefitthe gradual designgoal of the Digital Earth （Mountain）. The concept of the Digital Earth has not only caused great echoes in the world wide, but caused the government and the scienfists of the scientific and technical circles to pay close attention. Digital Mountain is the basic constituent of Digital Earth. China is the multi-mountains country, so that it is significant and necessary to design Digital Mountain. The paper elaborates the necessity and the feasibility of designing Digital Mountain, and introduces fourteen research contents, scientific system and key strut technologies of designing ＂Digital Mountain＂, At the same time, the paper points out that it is a long and complex system engineering for the establishment of Digital Mountain, which needs to pay equal attention to research and application and which is a long and arduous task, with challen- ges coexisting with chances.
