Vertical farms are one of the latest research directions in the interdisciplinary field of agriculture and the building environment. This article uses CNKI,Scopus and Web of Science (WoS) as databases,and selects 184 domestic and foreign related literatures by searching keyword. The bibliometrics methods are used to quantitatively analyze them,and summarize the current status and development trend of vertical farm research and the challenges. The results showed that the development of the first 10 years was relatively slow,and there were few related literatures published after the concept of vertical farms was proposed in 1999. After 2010,the development has accelerated,and the number of literatures has shown an overall upward trend. But regardless of the overall number or the inclusion of the core database,related research is still very insufficient. An analysis of 21 documents in the WoS core collection database found that the latest research focus is not only in the direction of agricultural science and technology,but also in the direction of environmental science,especially in the direction of the building environment. Based on comparatively analyzing the research content of various literatures,the research hotspots of vertical farms are further refined and summarized,and research methods are sorted out. At the same time,the technical,economic and feasibility of vertical farms are analyzed,and the direction of future technology development is elaborated.
