摘　　要：文中对定量分析不同降水时空尺度变化对盘锦地区分布式水文模拟的影响,结合分布式水文模型SWAT模型,采用静态和动态参数方法,分析4种降雨输入时段对区域洪水模拟精度的影响,并通过降水空间聚集方法对6种降雨空间分辨率下的洪水模拟精度进行分析。研究成果对于盘锦地区洪水模拟方案制定具有重要的参考价值。To quantitatively analyze the influence of the different space-time scale change of the rainfall on the distributed hydrological simulation in Panjin area, combined with SWAT distributed hydrological model, using the static and dynamic parameter method,the paper analyzes the influence of 4 kinds of rainfall input periods on regional flood simulation accuracy, and analyzes flood simulation accuracy under 6 kinds of rainfall spatial resolution through the rainfall spatial aggregation method. The research results has the important reference for the flood simulation scheme development of Panjin area.
