摘　　要：为分析简单式绿色屋顶模型模拟的准确性,基于降雨和径流监测数据模拟了不同构造的简单式绿色屋顶装置,研究了影响模拟准确性的因素。结果表明,装置构造、模拟连续性和降雨特征是影响简单式绿色屋顶滞留效果模拟准确性的主要因素。基质种类和规模不同的简单式绿色屋顶装置模型参数不能相互转移;基质种类相同但层厚度不同的装置模型参数可以相互转移,模拟准确性较好;采用不同排水层材料的装置模型参数具有良好的可转移性。简单式绿色屋顶在连续降雨条件下的模拟准确性优于单场次降雨条件。另外,降雨历时对模拟准确性有一定影响,较长的降雨历时可以提高模拟准确性。This paper simulated the extensive green roof devices with different structures based on rainfall and runoff monitoring data,and investigated the factors affecting the simulation accuracy,so as to analyze the simulation accuracy of extensive green roof model.The device structure,simulation continuity and rainfall characteristics were the main factors affecting the simulation accuracy of the retention performance.The model parameters of extensive green roof devices with different substrate types and scales could not be transferred to each other.The model parameters of devices with the same substrate type but different layer thickness could be transferred to each other,and better simulation accuracy could be obtained.The model parameters of the devices with different drainage layer materials had good transferability.The simulation accuracy of extensive green roof in continuous rainfall scenarios was better than that in single rainfall scenarios.In addition,rainfall duration had a certain influence on the simulation accuracy,and the longer rainfall duration improved the simulation accuracy.
