Abstract: Community gardens can help build a green, ecological, healthy, comfortable and economically sustainable living environment. Based on CiteSpace visual knowledge mapping analysis and literature analysis, this research defines the concept of community gardens and sorts out its evolution process both at home and abroad, and analyzes the research hotspots and trends. The results show that the development of community gardens are mainly in conformity with the social conditions and residents’ needs in different countries, and the overall development in China lags behind that of other countries, showing the trend from the study of landscape forms and spatial structures to ecological and health benefits. The focus of the research on community gardens mainly centered around community construction, public participation and ecological sustainability. This study puts forward that the research on community gardens with human health benefits, ecological governance, landscape planning, intelligent construction and management of community gardens are likely to become hotspots in the future.
