| 摘 要： | 海绵城市是指通过加强城市规划建设管理,充分发挥建筑、道路和绿地、水系等生态系统对雨水的吸纳、蓄渗和缓解作用,有效控制雨水径流,实现自然积存、自然渗透、自然净化的城市发展方式。其本质是要实现有效的径流控制,不仅要从形成雨水径流的源头着手,而且要考虑城市“海绵体”的岩土性质,其渗透能力(降雨渗透系数)、储存雨水能力(地下含水层储存空间大小)及储存雨洪的危险性(诱发环境地质问题)等。这些问题与水文地质勘查工作密切相关,不可或缺,是海绵城市建设规划、设计前的最基础性工作。

| Abstract: | Sponge city refers to the urban development mode of natural accumulation,natural infiltration and natural purification by strengthening the management of urban planning and construction,giving full play to the absorption,livestock infiltration and mitigation of rainwater by ecosystems such as buildings,roads,green spaces and water systems,effectively controlling the runoff of rainwater.Its essence is to achieve effective runoff control,not only starting from the source of rainwater runoff,but also considering the geotechnical properties of urban“sponge body”,its permeability(rainfall permeability coefficient),rainwater storage capacity(storage space size of underground aquifer)and the danger of rainwater storage(induced environmental geological problems),etc.These problems are closely related and indispensable to hydrogeological exploration,and are the most basic work before the planning and design of sponge city construction. |
