【摘要】：屋顶绿化作为海绵城市的主要控制指标之一,蓄截雨水的能力已获得多个实验证实。不过,在蓄截雨水的量化方面出现较大偏差,甚至同一个地区的不同实验也存在一定的偏差,造成实验的可重复性和可比性较差。通过系统综述,提取国内外有关屋顶绿化的实验数据,从时空维度、介质、结构、屋顶屋面和降水等方面系统整理蓄截雨水的17个影响因素,包括正向因素和负向因素、直接因素和间接因素。并根据因素之间的互作关系提出屋顶绿化径流量公式。最后依此提出实现实验可重复性和可比性的基本途径,即控制介质有机质含量、介质厚度、介质初始湿度、生物量、蓄水层和降雨强度等关键指标。研究结果为今后相关研究报道需要把握的必要条件提出了建议。
[Abstract]:As one of the main control indexes of sponge city, roof greening has been proved by many experiments.However, there is a great deviation in the quantification of the interception Rain Water, even in different experiments in the same area, which leads to the poor repeatability and comparability of the experiments.Through a systematic review, the experimental data of roof greening at home and abroad are extracted, and 17 influencing factors, including positive factors and negative factors, are systematically sorted out in terms of space-time dimension, medium, structure, roof roof and precipitation, etc.Direct and indirect factors.According to the interaction between the factors, the runoff formula of roof greening is put forward.Finally, the basic ways to achieve the repeatability and comparability of the experiment are put forward, that is, controlling the content of organic matter in the medium, the thickness of the medium, the initial humidity of the medium, the biomass, the aquifer and the rainfall intensity, and so on.The results provide suggestions for the necessary conditions to be grasped in future research reports.
