摘　　要：为提高涢水流域的洪水预报精度,缓解流域下游的防洪压力,更加科学地进行防洪调度,研究集总式三水源新安江模型在该流域的适用性。选取该流域1987年~1997年实测资料,采用SCE-UA算法优选模型参数,分析模拟洪水过程与实测洪水过程中的差异,总结新安江模型在该流域的适用性。结果表明:新安江模型模拟结果从洪量、洪峰及洪水过程角度都能达到《水文情报预报规范》规定的作业预报精度要求,该模型在涢水流域的适用性较好。In order to improve the accuracy of flood forecasting in the river basin, relieve the pressure of flood control in the lower reaches of the basin, and conduct flood control operations more scientifically, the applicability of the lumped three-source Xinanjiang model in the basin is studied. The measured data of the basin from 1987 to 1997 were selected, and the model parameters were optimized using the SCE-UA algorithm. This paper analyzes the difference between the simulated flood process and the measured flood process, and summarizes the applicability of the Xin’anjiang model in the basin. The results show that the simulation results of the Xin’an River model can meet the requirements of operation forecast accuracy stipulated in the Hydrological Information Forecasting Specifications from the perspective of flood volume, flood peaks and flood process. The model has good applicability in the river basin.
