The pandemic has revealed the need for citizens to have adequate and safe food, an enriched lifestyle, and more communication. Community garden, as an emerging agricultural model, is in line with current development themes of architecture, ecology, and energy. It enables self-production and marketing of agriculture, guarantees urban food security, enhances the resilience of the urban food supply, and plays a unique role in reducing transport and carbon footprints. Utilizing fragmented spaces between communities to create beautiful community garden can be a great way to experience the joys of farming and improve the air environment. It can also inspire people to participate in course training and enrich the knowledge base of community residents. Not only that, but psychologists believe that community garden is “green” in the sense of balancing the major forces in our lives—social, economic, and ecological. Community garden can provide a way to achieve this balance. Through the research of previous scholars and actual cases, this paper summarizes the development history and current situation of community garden, discusses the social function of community garden from the perspective of service design, and analyses the research on space and human health in community garden, intelligent construction and operation of community garden, and the research on community garden and social equity as possible development trends for community garden.
