摘要：

结合GIS与RS技术的分布式水文模型已成为当今水文界研究的重点。从气象与水文水资源学科交叉的角度对分布式水文模型VIC模型与SWAT模型进行研究，并将其应用于白莲河流域，以此探讨该模型在中小流域的适用性。模拟结果表明，VIC模型与SWAT模型在白莲河流域率定期与检验期的模拟效果相差很小。SWAT模型的效率系数与相关系数略高一些，SWAT模型的模拟效果比较平均，每年相差不大；但VIC模型在1995年和1999年模拟效果明显好于其它年份，尤其在2002年，VIC模型模拟的洪峰与实测的相差较大，从而影响总体的效率系数偏低，而SWAT模型模拟的更接近实测值。研究结果表明两种模型对于我国中小流域的径流模拟具有一定的适用性.

Abstract:

The distributed hydrological model has become the key issues of hydrology research based on the GIS and RS technology now.This paper introduces the VIC model and SWAT model from the interdisciplinary aspect of hydrology and meteorology.The two models were applied to Bailian River Valley of Hubei province to discuss its adaptability in flow simulation of the midsmall valley.Combined with DEM,vegetation and soil data,through model preprocessing,the framework of VIC model and SWAT model in Bailian river valley was established.The results show that the simulation difference of the VIC model and SWAT model is very small,the efficiency coefficient and correlation coefficient of the SWAT model are higher than that of the VIC model,and the annual simulation effect of the SWAT model is more average.But the simulation effect of the VIC model is better in 1995 and 1999 than in the other years;especially the flood simulation result is great distinct from the fact measure data in 2002,which lead to the whole lowness efficiency coefficient,the flood simulation result of the SWAT model approaches the actual data.The two distributed hydrological models can reflect the daily flow hydrological process of the basin on the whole and can be adaptable for the valley.
