| 摘 要： | GR4J是一个简单实用的概念性水文模型,在模型原理和结构上具有鲜明特色,目前在国内应用还较少。本文将该模型应用于赣江流域19个集水区域2003~2009年日径流模拟中。结果显示,在各集水区域,GR4J在检验期和率定期的确定性系数均达到0.85以上,径流总量相对误差在10%以内。因此,GR4J模型在赣江流域的日径流模拟中具有较高精度,具有较好的推广应用前景。

| Abstract: | The GR4J model is a simple and practical conceptual hydrological model with remarkable characteristics in model principle andstructure. At present, application of this model is rather infrequent in China. In this paper, this model was applied to the daily runoff simulationof 19 different catchments over the Ganjiang River Basin during the period from 2003 to 2009. Results show that the Nash-Sutcliffe efficiencycoefficients for all the study areas exceeded 0.85 and the water volume relative error values were with ±10% during the calibration andvalidation periods. Thus, GR4J performed well in simulating daily runoff in the Ganjiang River Basin and it is promising in further applicationin other regions in China. |
