摘要分布式水文模型用于实时洪水预报时，如何更新空间分布的状态变量是获得准确预报的一个重要问题。本文介绍了三种分布式水文模型在模拟过程中状态变量的更新方法。本文介绍的两种比值法，考虑了流域水文变量的空间分布。采用比值法对状态变量进行了成功的更新，得到了比不更新状态变量时更好的仿真结果。
Synopsis When a distributed hydrological model is used for real-time flood prediction, how to update the spatially distributed state variables is an important issue to obtain accurate prediction. This study introduces three methods to update the state variables in a distributed hydrological model during a simulation. The introduced methods here, two kinds of ratio method, consider a spatial distribution of hydrologic variables in a basin. With the ratio method, state variables are updated successfully and better simulation results can be obtained than when the variables are not updated.
