基于海绵城市建设指引的迁安市集雨型绿色基础设施体系构建策略初探

摘要

城市绿色基础设施作为海绵城市建设的重要载体，能够发挥出强大的集雨型功能。以迁安市集雨型绿色基础设施构建为研究对象，以汇水区划分、空间布局策略、径流控制级别、径流控制功能作为主要研究内容，通过田野调查和教学研讨等研究方法，梳理了京津冀地区由城市绿地系统作为主要载体的集雨型绿地系统的构建方法，归纳了集雨型绿色基础设施体系对绿地系统集雨功能的补充作用；结合专家访谈和课堂授课反馈信息，总结出海绵城市建设中存在的误区与偏差。以此来探讨符合京津冀地区城市实际情况的集雨型绿色基础设施体系构建策略，为海绵城市建设和城市绿地建设提供借鉴。%Urban green infrastructure plays a powerful function in rainwater-harvesting as an signiifcant carrier of Sponge City construction. With ifeld investigation and teaching research, the paper provides a summary of constructing methods of rainwater-harvesting green space system based on the green system in Beijing, Tianjin and Hebei areas. Choosing Qian'an rainwater-harvesting green infrastructure system as the research object, we put emphasis on catchment division, spatial layout strategy, runoff control level and runoff control function. The paper sums up the errors and deviations in the Sponge City construction, combined with expert interviews and teaching feedback information. It proposes the construction strategy of rainwater-harvesting green infrastructure system which could conform to the actual situation in cities of Beijing, Tianjin and Hebei areas and provides reference for the construction of Sponge City and urban green space.
