摘要
海绵城市是解决城市水环境系统问题的国际先进经验,建设下沉式绿地可有效削减径流强度,缓解路面内涝灾害,净化水质,减轻路面径流污染,提高水资源利用效率。一定的下沉深度可使绿地能渗蓄降雨和路面径流,节约灌溉用水并补给土壤水和地下水资源,有助于节约城市用水。应用海绵城市理论,以安顺娄湖为例优化绿地系统设计,研究下沉式绿地建设施工技术,降低了城市的洪涝灾害风险。
Sponge city is the international advanced experience of urban water environment system solutions.The construction of sunken green space can effectively reduce runoff intensity,alleviate Road Waterlogging Disaster,purify water quality,reduce road runoff pollution,and improve the utilization of water resources.A certain sinking depth can make the green space be able to store rainfall and road runoff,save irrigation water,and supply soil water and groundwater Resources,help to save water in cities.In order to reduce the risk of urban waterlogging,this paper uses the theory of flood prevention and construction to optimize the construction of urban green space.
