摘要: 近年来SWAT模型在我国南方湿润半湿润流域以及众多大尺度流域取得了良好的应用效果,但在水文资料缺乏、气候相对干旱的流域应用不多。以黄土高原典型流域陕西省延河流域为例,结合国内外已有的研究和GIS技术,根据延河流域现有的数据成功构建了基于SWAT的水文模型,其中1980—1985年为模型的率定期,1986—1989年为模型的验证期。通过对模型的参数进行敏感性分析以及一系列率定,最终得到结果为率定期的Nash-Sutcliffe效率系数NS和相关系数R2分别是0.644和0.832;验证期的Nash-Sutcliffe效率系数NS和相关系数R2分别为0.63和0.872,均达到模型模拟的要求,表明SWAT模型基本上能够模拟延河流域月径流量水文过程,为SWAT模型在黄土高原典型流域的进一步应用提供了科学依据。

Abstract: In recent years, SWAT (Soil and Water Assessment Tool) model has achieved good application result in humid south China,but in arid river basins in lack of hydrological data, it has not been widely used. In this research, the semi-arid Yanhe River Basin in Shaanxi Province was taken as an example.In association with GIS and RS technology, a hydrological model based on SWAT model for Yanhe River Basin was built. Data series from 1980 to 1985 were used to calibrate the SWAT model and data from 1986 to 1989 were employed to validate the model. The results are as follows: values of Nash-Sutcliffe coefficient and correlation coefficient are 0.644 and 0.832 respectively in calibration period, and 0.630 and 0.872 in validation period, meeting the requirements of model simulation. The results indicate that SWAT model well reflects the monthly runoff hydrologic process in Yanhe River Basin. The research offers a basis for the further application of SWAT model to river basins in the loess plateau of China.

Key words: SWAT model, monthly runoff simulation, Yanhe River Basin, loess plateau, applicability, sensitivity analysis
