摘要 基于海绵城市设计理念,以"慢排缓释,源头分散,生态环保"为特征对雨水进行收集、利用、排泄,设计出一种由粘土和堆肥作为基料,添加有农作物秸秆的生态育苗罐体、绿色吸水植物、塑料泡沫箱体等构成的生态屋顶集雨系统,将该系统置于城市小区楼房屋顶,对屋顶雨水进行收集、储存、利用及处理,以实现对城市雨水的就地消纳和利用,从而有效缓解城市雨水的径流压力,减轻城市雨水的排放负担,节约了资源,实现对城市中雨水的吸、渗、滞、蓄、用、排等多维功用。 Based on the design concept of sponge city,rainwater is collected,utilized and discharged with the characteristics of"slow drainage and slow release,source dispersion and ecological and environmental protection".An ecological roof rainwater collection system is designed which is composed of clay and compost as base material,and adding ecological seedling tank with crop straw,green absorbent plant,plastic foam box and so on.The system is placed on the roof of the building in the urban district,and the roof rainwater is collected,stored,utilized and treated to realize the local use and utilization of urban rainwater.Thus it effectively alleviates the runoff pressure of urban rainwater,lightens the discharge burden of urban rainwater,saves resources,and realizes the multi-dimensional functions of absorption,seepage,stagnation,storage,use and drainage of urban rainwater.
