摘要
黄河流域的水问题一直是人们十分关注的焦点 ,而流域水文模型又是解决这些问题的关键所在。本文总结了黄河流域产汇流及水文模型的研究现状与进展 ,指出了存在的不足。展望黄河流域水文模型的研究方向 ,一方面继续探讨半干旱半湿润地区径流形成的物理机制 ,另一方面研制建立分布式流域水文模型 。
The water problems in the Yellow river basin have always been focused and the watershed hydrological model is the key to solve these problems. On the basis of reviewing runoff generation and flow concentration mechanism as well as the hydrological model studies related to the Yellow river basin, the current research state and the existing problems are discussed. The future research direction of hydrological model in the Yellow river basin is on two aspects, one is to explore the runoff generation and flow concentration mechanism in the semi dry and semi humid region, the other is to develop distributed hydrological model as the basis of constructing the ‘digital Yellow river’ project.
