摘要:

以玉龙喀什河流域为研究区,使用中国气象同化驱动数据集(the China Meteorological Assimilation Driving Datasets for the SWAT Model,CMADS)驱动SWAT(Soil and Water Assessment Tool)水文模型进行径流模拟,评估了CMADS在该流域的精度以及对SWAT模型的适用性。结果表明:(1) CMADS的降水、最高气温和最低气温与地面水文测站获取的相应参数的相关系数分别达到了0.650、0.998和0.995,对气温的模拟结果明显优于降水;并利用协同克里金插值分析了CMADS在研究区的降水、最高气温和最低气温的时空分布特征,表明该数据集能够很好地反映下垫面地形特征,具有较高的质量。(2) SWAT模型在模拟月尺度径流方面,除极值模拟较差以外,率定期和验证期的纳什效率系数(Nash-Sutcliffe Efficiency Coefficient,NSE)分别达到了0.845和0.836,取得了较为满意的模拟结果。本文证明了CMADS+SWAT模式对高寒山区的水文模拟有很好的适用性,提供了在地面站点稀缺地区构建水文模型的替代方案,对寒旱区的水文模拟起到了一定的促进作用。

Abstract:

In this paper, the Yulong Kashi River Basin was selected as the research area, and the runoff simulation of SWAT hydrological model driven by The China Meteorological Assimilation Driving Datasets (CMADS) for the SWAT model was carried out to assess the accuracy of CMADS in the watershed and its applicability to the SWAT model. The results showed that (1) the correlation coefficients of precipitation, maximum temperature, and minimum temperature of CMADS with the measured hydrological stations were 0.650, 0.998, and 0.995, respectively, and their simulation of temperature was significantly better than that of precipitation. The spatial-temporal distribution characteristics of CMADS to precipitation and maximum and minimum temperatures were studied by using collaborative Kriging interpolation, which shows that the data set can well capture the topographic characteristics of the underlying surface in the study area, and its meteorological data has high quality. (2) With regard to runoff simulation of the SWAT model, except for poor simulation, the Nash-Sutcliffe efficiency coefficient of the periodic rate and validation period reached 0.845 and 0.836, respectively, and satisfactory simulation results were obtained. This paper showed that the CMADS+SWAT model had good applicability for hydrological simulation in the study area and provided an alternative to construct a hydrological model in areas with scarce ground stations, which plays a certain role in promoting hydrological simulation in cold and dry areas.
