随着数字地球(Digital Earth)的提出与实施,GIS的发展已经进人成熟期,数据多维化(3D & 4D GIS)、平台网络化(Web GIS),集成化成为GI.S的发展方向.GIS新技术应用于数字地震应急救灾,可以在后方逼真地模拟地震现场,为指挥者提供更丰富和更直观的救援信息,为现场救援提供强大的技术支持,为指挥员决策提供更科学的决策模型.文中就建设一个数字地震应急救灾系统提供了方法和理论支持,并在系统建设中作了些初步探索,应用GIS新技术与数字地震应急救灾结合建设一个信息平台.%With the proposal and application of Digital Earth, the development of GIS has entered the mature stage. The Mobile GIS and the Grid GIS are developing rapidly. The 3D&4D GIS,the WebGIS and the integrated GIS are the new direction of the development of GIS. The application of new GIS technology in digital earthquake emergency rescue may simulate realistic scene of earthquake. For the commanders, it may provide more richer and intuitionistic rescue information. For the site relief, it may provide powerful technological support. For the commander, it may provide more intelligent decision-making model. In this paper, building a digital earthquake emergency relief system provides methods and theoretical support, and construction in the system made some exploration.
