为了准确客观地了解国内公园绿地的研究现状，把握公园绿地领域的研究热点及发展趋势，基于 CiteSpace 软件，依托中国知网（CNKI）数据库，对 1992—2020 年以“公园绿地”为主题的文献进行统计分析。结果表明，近 30 年间，公园绿地研究主要集中于 3 个层面：1）绿地系统、防灾公园及国家公园的规划；2）公园绿地的可达性、空间布局以及优化策略；3）景观格局和生态修复策略。可达性、景观生态学、布局优化及植物群落是近几年研究的热点，公园尺度的可达性、市域层面的指标评价及环境恢复性知觉是公园绿地研究的新角度。

In order to accurately and objectively understand the research status of public park, and grasp its research hotspots and development trends, based on the CiteSpace software, relying on the China National Knowledge Base (CNKI) database, a statistical analysis of the literatures on the theme of "public park" published from 1992 to 2020 is carried out. The results show that in the past 30 years, the research on public park mainly focused on three levels. The first is the planning of green space systems, disaster prevention parks and national parks. The second is the accessibility, spatial layout and optimization strategies of public park. And the third is the landscape pattern and ecological restoration strategies. Accessibility, landscape ecology, layout optimization and plant communities have been the hot topics of public park research in recent years, while park-scale accessibility, city-level indicator evaluation and perception of environmental restoration are new perspectives.
