Urban Green Space Research Progress and Hotspots Evolution Analysis: Visual Analysis based on WOS

Background and objective: Over the past few decades, urban green space research has emerged as a pivotal field withinurban planning, ecology, and environmental science, achieving substantial advancements. This study endeavors toelucidate the trajectory of development and evolving hotspots in urban green space research through a visual analysis ofthe Web of Science (WOS) database. Methods: This study employs CiteSpace software to visualize the dataset, encompassing the analysis of keywords,abstracts, institutions, authors, references, and more, presenting the knowledge structure graphically. Additionally, itutilizes the LLR tag extraction algorithm to generate a keyword co-occurrence map and conduct clustering and grouping. Results: The findings reveal that the preeminent contributors in urban green space research include Haase, Dagmar, andNizamani, Mir Muhammad. Furthermore, the collaborative network among researchers underscores the significance ofinterdisciplinary and cross-border cooperation in advancing urban green space research. Keyword co-occurrence analysisidentifies prevalent themes such as land surface temperature and health, highlighting the current focal points of urbangreen space research. Conclusion: This study discerns heightened attention to topics encompassing the thermal environment, ecosystemservices, biodiversity, green space accessibility, and vegetation. These themes mirror societal concerns regarding theinfluence of urban green spaces on climate change and spatial planning, thereby delineating avenues for future research.
