| 摘 要： | GR3降雨径流模型属概念性集总式水文模型,具有结构简单、参数少的特点。为研究GR3降雨径流模型在我国的适用性,在长江、黄河、淮河和松花江水系,选择了7个不同尺度、不同气候条件的代表流域试用,以四种误差函数评定模拟效果。结果显示,GR3降雨径流模型在整体过程和水量平衡方面均取得较高的精度;在连续模拟中能够保持令人满意的次洪精度;比较接近的验证期与率定期精度体现了其较好的稳定性;该模型在湿润地区的表现优于半湿润地区。可以说,GR3降雨径流模型在我国有很好的应用前景。

| Abstract: | GR3 has a simple structure, a parsimonious number of parameters which are easy to be calibrated. It is a lumped and conceptual hydrological model for rainfall-runoff simulation. In order to test its applicability in China, seven representative basins were selected from the river systems of the Yangtze, Yellow, Huaihe and Songhuajiang. The simulation was assessed with 4 criteria. The study demonstrates that GR3 is satisfactory in long term continuous and event simulation and water balance, stable between the periods of simulation and validation, and has better performance in humid areas than semi-humid ones. It can be concluded that GR3 is applicable in China. |
