LID理念下的韩国绿色基础设施建设实践与启示——以德津湖流域为例

Practice and enlightenment of green infrastructure construction in South Korea based on LID concept:a case of Deokjin Lake basin

韩国德津湖流域因水质恶化被指定为优先治理水域。近些年,该流域通过水生态修复项目,重获可持续的生态安全城市面貌和水友好型城市宜居环境。以德津湖流域为研究区域,梳理和介绍了其水生态修复过程中关于“德津湖流域LID-绿色基础设施建设项目”的实施背景、相关政策、技术方法、实践应用及其产生的协同效益,进而分析总结出其水生态修复实践的方法和具体策略,以期从低影响开发、多组织协作和多目标统筹3个方面为中国城市水生态修复建设提供借鉴与启示。

Due to the deteriorating water quality,the Deokjin Lake basin in South Korea was once designated as a national water area prioritized for treatment.After years of water ecological restoration,this region has regained its urban identity as a sustainable and ecologically safe area and its livable environment as a water-friendly city.Taking the Deokjin Lake basin as the research object,this paper introduces the implementation background,relevant policies,technical methods,practical application and synergistic benefits of“Deokjin Lake Basin LID-Green Infrastructure Construction Project”,and then analyzes and summarizes the specific methods and strategies employed in the practice of its water ecological restoration,hoping to provide reference and enlightenment for urban water ecological restoration and construction in China from three perspectives:low-impact development,multi-organizational collaboration and multi-objective coordination.
