摘要
公园绿地具有雨水下渗、滞留、调蓄等功能,但作为海绵城市核心内容的重要组成部分,往往缺乏与城市雨水管理系统建立联系。在总结首批国家海绵城市试点城市中部分公园绿地的径流控制与调蓄能力的基础上,梳理当前公园绿地布局选址、设计层面较少考虑雨水控制等问题,提出已建公园改造和新建公园规划的思路,以及干式和湿式两类公园绿地基于雨水蓄排结合的设计方法,并以某城市片区生态防涝体系构建为例进行分析,以期为城市公园绿地增强海绵效应提供参考。
Urban park green space has the functions of stormwater infiltration,detention and retention etc.But as an important part of the sponge city core content,the park green space often lacks the connection with the urban stormwater management system at present.On the basis of summarizing the stormwater runoff detention and retention capacity of park green space in the first batch of national pilot sponge city,the problems of less consideration of stormwater control in park layout and design were sorted out,and a thought of built park renovation and new park planning was stated.A design method based on stormwater storage and detention for dry and wet park green space was proposed with a case study,so as to provide a reference for urban park green space to enhance the sponge effect.
