摘　　要：针对当前数字流域构建中存在的问题,在分析数字流域信息、内涵和逻辑结构的基础上以虚拟地球为平台,将3S、3DMax等作为辅助数据处理和建模工具,采用KML组织存储数据耦合各类水环境模型,使用组件开发技术、三层逻辑框架结构,快速、简捷地构建了数字流域平台的集成方案,并以沣河为例,选用GoogleEarth为基础平台建立了数字沣河流域平台。实例应用结果表明,基于虚拟地球的数字流域平台正确、可行、有效。Aiming at the drawbacks of constructing digital valley at present, on the basis of analysis of digital infor- mation of basin, connotation and logical structure, this paper establishes a quick and simple integration scheme based on virtual earth by combination of component technology and three-layer logical framework structure and using 3S and 3DMax as tools of auxiliary data processing and modeling. At the same time, KML is adopted to organize and store data with coupling various models of water environment. Taking the Fenghe River for an example, Google Earth is selected as the basic platform to establish digital Fenghe River basin. The instance example shows that the digital basin platform is correct and effective.
