摘　　要：以径流源头控制的重要实施区域——建筑小区为研究对象,提出了绿色-灰色耦合雨洪调蓄系统的构建流程,并对具有调蓄功能的绿色基础设施及灰色设施建立调蓄容积估算模型,针对高、低开发强度两类建筑小区分别建立适宜的绿色-灰色耦合雨洪调蓄系统。研究结果表明,在低开发强度小区,通过合理构建具有调蓄功能的绿色基础设施即能够满足高年径流总量控制率的调蓄要求;而在高开发强度小区,通过增加下垫面的渗透比例能够有效降低小区所需的调蓄水量,从而减少灰色设施的建设规模。Building site, which was an important implementation area of runoff source control, was taken as the research object, construction procedure of green - grey stormwater detection and retention system was proposed, and a storage capacity estimation model was established for green infrastructure and gray facilities with storage function. For high and low construction density site, two kinds of appropriate green -grey stormwater detection and retention systems were built respectively. The results indicated that in the low density building site, green infrastructure with storage function which was reasonable construc- ted could meet the storage requirements of high volume capture ratio of annual rainfall; in high density building site, storage capacity could be effectively reduced by increasing the infiltration ratio of the un- derlay surface, so as to reduce the grey infrastructure construction scale.
