随着我国城市化进程深入推进,城市数量与日俱增,城市规模也越来越大。但是,城市弊病也更加突出,如城市内涝频繁出现,径流污染不断加剧,城市面临着水资源短缺的现状,不利于城市今后的发展。对此,要将海绵城市理念运用到城市规划与建设中,坚持生态优先的理念,将绿色和灰色基础设施结合起来,在保证城市水安全的基础上,实现雨水在城市区域内的积存、渗透与净化,让城市雨水资源得到有效利用,为生态环境提供有力保护。本文将简述海绵城市建设的原因与意义,并结合实例探讨了海绵城市理念下城市规划与设计方案。
With the deepening of China’s urbanization process, the number of cities is increasing day by day, and the size of cities is also growing. However, the disadvantages of cities are also more prominent. For example, frequent urban waterlogging and increasing runoff pollution, cities are facing the current shortage of water resources, which is not conducive to the future development of the city. In this regard, sponge city concept should be applied to urban planning and construction, adhere to the concept of ecological priority, green and gray infrastructure will be combined to ensure the safety of urban water on the basis of the accumulation of rainwater in urban areas, penetration And purification, so that urban rainwater resources are effectively used to provide effective protection of the ecological environment. This article will outline the sponge city construction reasons and significance, and with examples to explore sponge city concept of urban planning and design.
