| 中文摘要: |
| 本文对数字流域的框架研究、基础平台建设、数字流域模型及相关技术、数字流域应用系统建设四个方面的研究进展进行了综述。数字流域的整体框架可分为三层：数据层、模型层和应用层。其中数据层的建设在我国已经初具规模；模型层中对分布式模型的研究较多，基于数字高程模型提取河网的技术已经比较成熟，在国内外许多小流域都建立了分布式水文模型；应用层由于缺乏全流域整体模型的支撑，目前的研究主要是提供数据服务以及一些专题的决策支持服务。综合前人的研究发现当前紧要任务就是在大范围、全流域上建立起具有应用价值的数字流域模型。 |
| 英文摘要: |
| A review on advancement of study on digital riverbasin is given from the viewpoints of framework of study, construction of fundamental platform，digital riverbasin model and its relevant technology and construction of application system. The framework of study consists of three layers: data layer, model layer and application layer.The construction of data layer, which is the fundamental layer, is nearly accomplished in China. On the model layer, the development is in the stage of studying small drainage basin and is going to be expanded to large river basins. Referring to the application system，at present，the study is limited in the fields of data providing and decision making support for some specific topics due to lack of comprehensive model describing the whole riverbasin. Therefore，the construction of a practicable digital model suitable for large riverbasin is the urgent task in the development of digital riverbasin. |
