系列化水文模型研究

在大尺度水文模型研究中，提出了系列化水文模型的研究途径，即将不同时间尺度的同一种概念性水文模型构成一组模型系统，建立其间结构和参数联系，进行系列化研究。本文建立了新安江流域水文模型的月，日，时三种时间尺度的模型系列，在淮河流域上进行试验，初步显示了这种途径的作用。

Multiscale Hydrologic Modeling

A multiscale hydrologic model set including monthly, daily, and hourly data based models is able to use a wide range of data from longer series of monthly data to more detailed hourly data, and thus may abstract more information from the data available. The consistency of calibrated parameters between the hierarchy of models should give a sound reliability and reduce the uncertainty. Moreover, the results from the multiscale models may provide an insight into the scale effects on hydrologic processes. The Xinanjiang Model is selected for the construction of the hierarchy of multiscale model. The multiscale modeling has been carried out for the Huaihe River basin with an area of 120 000 km 2. The parameters from the three levels are matched with each other and the relationship between the scales is replaced with geographical conditions to a certain degree.
