摘要
本文结合国家第一批海绵城市建设试点市中的安徽省池州三台山公园改造项目实例,分析了低影响开发雨水利用技术措施(Low-Impact Development,简称LID)在城市山地公园生态改造中的具体实施应用。基于对公园地形、竖向和排水分区等分析,优先改造公园原有绿地、广场铺装、园路等用地和雨水管网设施,综合确定低影响开发设施的类型与布局,包括雨水滞留、下渗、净化、利用等,将雨水控制与园林景观设计良好衔接。改变单纯依赖市政排水管道的快排模式,把公园建设为城市的"海绵体",实现公园雨水可资源化利用,达到可持续水循环,在此基础上总结了LID在城市公园海绵城市建设中的技术流程。最后分析了实施城市公园海绵的经济、社会和环境效益,并对未来LID在国内城市公园推广和应用提出建设性意见与策略。
According to the national first batch of pilot cities for the construction of the sponge in the Anhui province Chizhou Three Taishan park renovation project as an example,analyzed the Impact of Low Development of rainwater utilization technology measures(Low Impact Development,LID) application in city mountain park ecological reconstruction in the concrete implementation.Based on the analysis of terrain park,vertical and drainage partition,first transform the original campus green space,square shop,garden road,such as land use and rainwater pipe network facilities,comprehensive type and layout of the low impact development facilities,including water retention,infiltration,purification and utilization,etc.,will rain control and good landscape design.Rely on municipal drainage pipeline of change model,the park construction as the city's "sponge",implement park rainwater resource utilization,to achieve sustainable water cycle,on the basis of summarizing the LID sponge in city parks in the urban construction technical process.In the final analysis the implementation of urban park sponge economic benefits,social benefits and environmental benefits,and LID for the future in the promotion and application of domestic city parks put forward constructive Suggestions and strategies.
