摘要
再分析资料作为水文模拟研究中的重要资料,在气象站点数据匮乏地区替代站点实测数据方面具有非常重要的作用。以新疆额尔齐斯河流域为例,使用哈巴河、布尔津、福海、阿勒泰和富蕴气象站点数据驱动SWAT模型,并利用CN05.1再分析资料补充克拉他什水文站点周边气象数据,分析CN05.1再分析数据对SWAT模型径流模拟精度的提高程度。结果表明,与未进行气象数据补充前对比,率定期纳什系数N_(NSE)、决定系数R^(2)分别提高了8%、6%,验证期N_(NSE)、R^(2)分别提高了8%、15%,说明在气象资料匮乏地区,CN05.1再分析资料能较好地补充该地区气象条件。
As an important data in hydrological simulation research, reanalysis data plays a very important role in replacing the measured data of meteorological stations in areas where the data of meteorological stations are scarce. Taking the Irtysh River Basin of Xinjiang as the research object, the data of Haba River, Buerjin, Fuhai, Altay and Fuyun meteorological stations were used to drive SWAT model, and the CN05.1 reanalysis data was used to supplement the meteorological data of kratash hydrological station. And then the improvement degree of the CN05.1 reanalysis data to the runoff simulation accuracy of SWAT model was analyzed. Compared with before the meteorological data supplement, the results show that the Nand R~2 increased by 8% and 6%, respectively. During the validation period, the Nand R~2 increased by 8% and 15%, respectively, indicating that the CN05.1 reanalysis data can better supplement the meteorological conditions in the region with insufficient meteorological data.
