摘要: 利用流溪河模型对广东省内白盆珠水库的入库洪水进行模拟计算与分析研究。采用200 m精度的DEM数据、1 km的土地利用类型和土壤类型数据构建了模型,并将流域水系分为5级不同的河道,通过在河道上设置结点将河道分为48条虚拟河段,对不同的虚拟河段赋予不同的河道参数。在给定模型参数初值的基础上,分别用3场和11场洪水对模型参数进行了调整和验证。结果表明,流溪河模型对白盆珠水库入库洪水的模拟效果较好,推求的参数具有物理基础,对于洪水模拟具有广泛的适用性,在洪水模拟及预报方面有巨大的潜力。

Abstract: The LMS(Liuxihe Model) is a complete distributed physicsbased hydrological model,which is used to simulate and analyze the income flood of the Baipenzhu Reservoir in Guangdong province. The model is set up with DEM of precision of 200 m, landuse and soiltype of precision of 1 km. The basin is divided into five different watercourses which contain 48 virtual reaches according to crunodes set artificially,and then different reaches are given different initial parameters. Based on these given parameters,three floods and 11 floods are used to adjust and validate these initial parameters,respectively. The results indicate that parameters adjusted are of physical-base.The LMS model can simulate the income flood of the Baipenzhu Reservoir well and has extensive applicability and huge potential for floods simulation.
