中文摘要：

GR3模型结构简单，只有3个可自动优选的参数，已在欧洲、非洲、南美等地取得理想的应用效果。为验证其在我国的适用性，特选择分布于长江、黄河、淮河、松花江水系的7个代表流域，与国内普遍应用的三水源新安江模型进行对比。结果表明，GR3模型可媲美新安江模型，在我国具有相同的适用性。

英文摘要：

The GR3 model has a simple structure with only three parameters which can be automatically optimized. The model was developed in Europe, Africa, and South America. In order to verify its applicability in China, the GR3 model was compared with the Xin＇anjiang model in the seven representative watersheds situated in the fiver basins of Yangtze, Huaihe, Yellow and Songhuajiang where the Xin＇anjiang Model is recognized applicable. The comparison concludes that the GR3 model is comparable to the Xin＇anjiang model in terms of the model efficiency, water balance and correlation, and has the same applicability in China.
