中文摘要：
为研究不同水文模型在半湿润半干旱地区老哈河流域上的适用性，分别选取老哈河流域的西泉、初头朗两个子流域1970-2003年的实测资料，应用新安江模型和垂向混合产流模型进行模拟计算，并对比分析其模拟结果。结果表明，在西泉和初头朗流域，垂向混合产流模型的模拟精度总体上均高于新安江模型；垂向混合产流模型更适用于初头朗流域。
英文摘要：
In order to examine the applicability of different hydrological models in the Laoha River Basin which is located in a semi-humid and semi-arid region, the Xin＇anjiang model and the Vertically-mixed Runoff models are employed to the Xiquan and the Chutoulang subbasins in the Laoha River Basin with the same time series of data from 1970 to 1003, and the simulated results are compared and analyzed. The results show that the simulation accuracy of the Verticallymixed Runoff models are higher than that of the Xin＇anjiang model in both subbasins. Compared with the Xiquan Subbasin, the Vertically-mixed Runoff models are more suitable for the Chutoulang Subbasin.
