摘要:
利用雨洪管理模型（SWMM）对低影响开发（LID）设施进行效果评估已经成为一种普遍的技术方法，但在向子汇水区添加LID设施时，若LID设施未占据整个子汇水区，则会引起子汇水区的渗透子面积、洼地蓄水不渗透子面积、无洼地蓄水不渗透子面积的重分割，随之产生模型误差。利用SWMM子汇水区等效分割基本原理，研究向汇流方式为Outlet的子汇水区中添加LID设施的模拟误差特点。结果发现，所添加LID设施状态为出流不进入渗透子面积时，随着子汇水区重分割而产生的模型误差较小，这种误差随着子汇水区的最大地表漫流路径长度属性以及LID设施面积比例的增加而增加。
Abstract:
Application of storm water management model (SWMM) to evaluate the performance of low impact development (LID) facilities has become a common technical method. However, when LID facilities are constructed in a subcatchment area and the facilities do not occupy the whole area, it will cause re-partitioning of pervious area, impervious area and zero-impervious area, resulting in model errors. Based on the basic principle of subcatchment area equivalent partitioning of SWMM, simulation error characteristics of adding LID facilities to subcatchment area with catchment mode of Outlet were explored. When the LID facilities outflow did not enter the pervious area, the model error caused by the re-partitioning of the subcatchment area was smaller, and this error increased with the increase of the maximum surface overflow path length and the proportion of LID facility area in the subcatchment area.
