摘　　要：北京市山丘地区洪水具有汇流快、历时短、破坏强的特点,多发于夏秋季汛期,损失惨重。为此需建立水文预报系统,采用分布式水文模型(EasyDHM)和马斯京根汇流模型演算方法分别进行产、汇流计算,模拟再现漫水河站近几十年内发生的洪水事件。结果发现,率定期参数敏感性分析和优化之后的模型模拟精度有明显提高;验证期模拟洪水发生年份距离模型率定年份越近模拟效果越好,且模拟洪水的洪量模拟效果优于洪峰模拟。The flood cases concentrate mostly in summer and autumn at mountains areas of Beijing.The flood recedes fast but forms suddenly,which is destructive and brought great loss in life and property.The EasyDHM rainfall-runoff model and Muskingum model are applied to simulate the flood cases during the recent decades at Manshuihe Basin.The simulated results perform more accurately after the parameter sensitivity analysis and optimization,while at validation period it illustrated that the simulated results could approach to the observed flood process better if the year of flood case was near to the calibration year.The flood volume performed better than the flood peak value in simulating.
