低碳城市建设背景下日本近 20 年屋顶绿化研究进展

Progress of Green Roofs Research in Japan in the Past 20 Years in the Context of Low Carbon City Construction

摘要:

屋顶绿化对改善城市热岛效应和减碳意义重大，是日本建设低碳城市及实现“碳达峰”的有效举措。 通过文献计量学方法分析 Web of Science^TM 和 J-stage 两大数据库中日本近 20 年的屋顶绿化研究文献，并与日本屋顶绿化政策、法规出台的时间节点进行对照，将日本屋顶绿化研究分为 3 个 时期：低碳研究初始阶段（2000—2005 年）、低碳研究发展阶段（2006—2013 年）、低碳研究探索阶段（2014—2023 年）。同时运用文献计量学中高频词研究方法，解析不同时期日本屋顶 绿化研究内容，总结各时期研究特点，为我国屋顶绿化提供启示：完善法规政策、明确责任主体，推动地方出台激励措施并建立公众参与机制；加强地区适应性植物培育配置研究，深化节能减碳评价研究，重视废弃物应用研究。

Abstract:

Green roofs are crucial for improving the urban heat island effect and reducing carbon emissions, serving as an effective means for Japan to construct a low-carbon city and reach carbon peak. This paper employs the bibliometric method to analyze the green roof research literature in Japan from 2000 to 2023 in the Web of ScienceTM and J-stage databases and compares it with the timeline of relevant policies and regulations. The research is classified into three stages: the initial stage (2000-2005), the development stage (2006-2013), and the exploration stage (2014-2023). By using the bibliometric highfrequency word research method, the research contents and characteristics of each stage are explored. Implications for China are as follows: in policy, improve laws, clarify responsibilities, promote local incentives and public participation; in technology, enhance research on plant cultivation and configuration, deepen energy and carbon assessment, and focus on waste utilization.
