供需平衡视角下近十年城市绿地研究现状、热点主题与演进趋势

Research Status,Hot Topics,and Evolution Trends of Urban Green Space in the Past Decade from the Perspective of Supply and Demand Balance

存量发展与国土空间规划交织背景下,城市用地趋于集约高效建设。作为可以反映人地关系的量化研究,城市绿地供需平衡是城市空间公平正义重要的研究内容之一,有助于城市绿地空间布局优化和品质提升,持续增进民生福祉。借助Cite Space软件,对国内外近十年城市绿地供需平衡相关研究从起源、现状热点及未来趋势等角度进行分析,厘清发展脉络。分析结果表明:研究成果呈现三个阶段,2017年起稳定上升;当前研究热点主要集中在绿地可达性、尺度效益与空间分异、多元与异质群体需求、公平正义等方面;未来可以从供给侧规划转向需求侧优化、绿地单元从城市到社区延伸、互通多元化与绿色场景化呈现、供需平衡向匹配转换等方面深化研究。

Under the interweaving of built-up area redevelopment and land space planning,urban land tends to be intensively and ef-ficiently constructed.As a quantitative research that can reflect man-land relationship,the balance of supply and demand of urban green space is one of the important research contents of urban spatial justice and equity,which helps to optimize the layout and quality of urban green space,and continuously improve people's well-being.The supply-demand balance of urban green space is an important research topic for urban spatial justice and equity.Using CiteSpace software,this article analyzes the research on the supply-demand balance of urban green space in the past decade both domestically and internationally from the perspectives of origin,current hot topics,and future trends,clarifying the development path.The analysis results show that research achievements have presented three stages,with a stable increase since 2017.Current research hotspots mainly focus on the accessibility of green space,scale benefits and spatial differentiation,diverse and heterogeneous group needs,fairness and justice,etc.In the future,research can be deepened in the following areas:shifting from supply-side planning to demand-side optimization,extending green space units from cities to communities,presenting interactive diversity and green scenarios,and converting supply-demand balance to matching.
