为探究工业园区功能分区对园区LID设施不同布局方式调蓄效果的影响及最佳LID设施组合方案，以广东省某工业园区为研究对象，采用SWMM软件分别探究了单项LID设施分区布设的调蓄效果及多种LID设施组合布设方案的综合调蓄效益。结果表明，受园区功能分区影响，当研究区域下游绿化位置集中且降雨量相对较小时，集中中游布设的LID设施效果优于集中下游布设的效果，随着降雨增大，下游的调蓄优势才能充分发挥。LID设施组合设计时，5%绿色屋顶+15%下沉式绿地的组合方案，其单位布设面积调蓄效果最佳。因各设施之间相互影响，组合方案效果不如二者单独布设数据的算术求和，未能产生“1+1>2”的叠加效应。

To explore the storage effect of functional zoning on different layout methods of LID facilities in industrial parks and identify the optimal LID facility combination scheme, a specific industrial park in Guangdong Province was selected as the subject of study. The software SWMM was employed to investigate the storage effect of individual LID facility layouts and the comprehensive storage benefits of various LID facility combination schemes. The results show that affected by the park's functional zoning, when the downstream greening positions in the study area are concentrated and the rainfall is relatively low, LID facilities installed in the middle of the concentration area demonstrate superior effectiveness compared to those installed downstream. As the rainfall increases, the downstream's storage advantages become fully apparent. When designing LID facility combinations, the scheme combining 5% green roofs and 15% sunken green spaces yields the best storage effect per unit layout area. However, due to the mutual influence among facilities, the effectiveness of this combination scheme is not as good as the arithmetic sum of the data for the individual facilities, failing to produce the desired synergistic effect of "1+1>2".
