摘要/Abstract

摘要： 以富春江水库控制流域为研究区域，利用中国大气同化驱动数据集（CMADS V1.1）驱动SWAT水文模型，对富春江水库控制流域进行了逐日径流模拟，探讨了流域2008-2016年径流变化及水量平衡过程。结果表明：CMADS V1.1数据集驱动SWAT模型对研究区域的径流变化具有较好的模拟效果，在验证期，逐日模拟的效率系数大于0.70，决定系数大于0.75，达到了模型评价标准。在流域水量平衡各项中，地表径流和蒸散发为主要的输出项，分别占降水量的57.2%和36.2%，其中蒸散发量年际变化较为平稳。降水量、地表径流量、土壤对地下水补给、地下侧流量、蒸散发量最大值均出现在6月，最小值均出现在1月。流域径流量以地表径流为主，其在各个月份与月降水变化趋势基本一致。而基流量较小，且各月基流量对降水量的响应并不显著。

Abstract: The runoff distribution and water balance process in Fuchunjiang Reservoir watershed basin regarded as the studied area from 2008 to 2016 were investigated based on the daily runoff simulated by SWAT model driven with the China Meteorological Assimilation Datasets (CMADS).The results show that the SWAT model using CMADS as meteorological forcing data has a good performance in simulating the variation of runoff in Fuchunjiang Basin.During the verification period,the Nash-Sutcliffe efficiency coefficient and the coefficient of determination for the daily runoff simulation are respectively above 0.70 and 0.75,which reaches the model evaluation criteria.Among the water balance elements of the basin,the main output items of the surface runoff i.e.the surface runoff and the actual evapotranspiration account for 57.2% and 36.2% of annual precipitation,respectively.Compared with the precipitation,the interannual variation of actual evapotranspiration is small.In addition,the maximums of the precipitation,the surface runoff,the soil water supply,the lateral flow,and the actual evapotranspiration appear in June,and their minimums appear in January.The surface runoff is the dominant component of the basin runoff,and its monthly change trend is consistent with that of precipitation.Whereas the base flow is much less than surface runoff,and the response of the monthly base flow to precipitation is not sensitive.
