A method for drawing P~P_a~R correlation diagram using the storage model

提出了一种利用蓄满产流数学模型绘制降雨径流相关图的方法，该方法首先根据流域历史资料结合流域自身特性确定蓄满产流模型的结构，并优选出模型参数；其次，利用优选后的蓄满产流模型结合历史数据绘制相关图。黑河流域应用实例表明，应用该方法绘制的相关图简便实用、精度较高。

A method for drawing the P~Pa~R correlation diagram by using the storage model is proposed in this paper. Firstly, based on the historical data and the characteristics of the basin, the structure of Nature Storage model is selected, and the parameters of the model are optimized. Secondly, based on the average of cumulative process of rainfall and corresponding runoff events, the P~Pa~R correlation diagram can be drawn. This method has been applied to Heihe basin and the results are satisfisfactory. 
