摘要
为实现水问题研究的信息化处理 ,必须做大量的基础性工作 ,解决现实对象抽象和信息化后的表达问题 ,基于物理联系 ,定义各种特征的连接关系 ,信息化前人研究成果的集成问题。分析了流域数据模型的特征、组成、结构 ,以及特征之间的相互关系 ,建立了流域数据模型 。
In order realize data processing of water problems, huge data must be developed in the program: including natural objects abstracted, expressing of objects and relationships definition of features based on physical relationships, digitizing and integrating data.
