摘　　要：为研究小型水库群对流域洪水过程的影响程度,在三水源新安江模型的基础上,引入自溢式虚拟水库对产汇流环节进行改进,构建了受无调控小水库群影响的流域洪水预报模型。将改进的新安江模型应用于流域模拟中,对比分析改进、无改进新安江模型模拟结果表明,改进的新安江模型对于寿昌江流域具有良好的适应性,并能显著提高洪水模拟精度。研究成果可为无调控小水库群影响的流域洪水预报提供参考。In order to study the influence degree of small reservoirs on the flood process in the small basin,based on the three sources Xin'anjiang model,the self overflowing virtual reservoir was introduced to improve the production flow links.And then a basin flood forecasting model affected by unregulated small reservoirs was established.The improved Xin'anjiang model was applied to the simulation of the basin.Compared the improved and unimproved Xin'anjiang model results,it shows that the improved Xin'anjiang model has good adaptability to the Shouchangjiang Basin and can significantly improve the accuracy of flood simulation.The research results can provide reference for basin flood forecasting caused by unregulated small reservoirs.
