摘　　要：中国是世界上洪水灾害发生最频繁的国家之一。建立准确可靠的洪水预报程序是应对洪涝灾害的关键。中国南方的某水库流域属于亚热带季风气候,春季雨水较多,夏季暴雨集中,秋季有台风。坝址洪水多为中小型洪水,具有典型的山洪上升陡、下降缓的特点。为了探索流溪河模型在某水库洪水预测中的适用性,基于DEM、土地利用和土壤类型数据,建立了水库流溪河预测模型,并选取1个典型的洪水事件,利用粒子群优化算法对参数进行优化,并通过模拟其他洪水验证了模型的准确性。China has experienced one of the most frequent flood disasters in the world.Accurate and reliable flood forecasting programs are key to responding to flood disasters.A reservoir basin in southern China has a subtropical monsoon climate,with more rain in spring,concentrated rainstorm in summer and typhoon in autumn.The floods at the dam site are mostly small to medium-sized floods,with typical characteristics of steep rise and slow decline of mountain floods.In order to explore the applicability of Liuxi River model in flood prediction of a certain reservoir,Liuxi River prediction model was established based on DEM,land use,and soil type data.A typical flood event was selected,and the parameters were optimized using particle swarm optimization algorithm.The accuracy of the model was verified by simulating other floods.
