海绵城市建设技术

Sponge city construction technology

海绵城市是一种综合性、多元化的城市生态系统,是以保护、修复和利用自然水循环系统为主要目标,其可实现城市的可持续发展。通过收集、过滤、回用和渗透等方式,合理利用雨水资源,降低洪涝灾害风险,减轻城市排水系统的压力。利用绿化和自然化手段,增加城市绿地面积和植被覆盖率,以提高城市的生态环境和空气质量。城市通过铺设透水铺装、建设绿色屋顶和垂直绿化等措施,提高了城市地表的透水性,促进自然水文循环,改善城市排水系统,通过建设雨水花园、湖泊等方式,提高了城市的抗洪排涝能力,缓解了城市洪涝灾害的风险。通过列举深圳市采用城市海绵技术建设的具体案例,印证了城市海绵技术带来的社会效益。

Sponge city is a comprehensive and diversified urban ecosystem that aims to protect,restore,and utilize the natural water cycle system,achieving sustainable urban development.By collecting,filtering,reusing,and infiltrating rainwater resources,we can make rational use of them,reduce the risk of flood disasters,and alleviate the pressure on urban drainage systems.Utilize greening and naturalization methods to increase urban green space area and vegetation coverage,and improve the ecological environment and air quality of the city.By laying permeable pavements,constructing green roofs,and vertical greening,cities can improve the permeability of urban surfaces,promote natural hydrological cycles,improve urban drainage systems,build rain gardens,lakes,and other measures to enhance the city’s flood resistance and drainage capabilities,in order to alleviate the risk of urban flooding disasters.By listing specific cases of using urban sponge technology in Shenzhen,the social benefits brought by urban sponge technology have been confirmed.
