Knowledge graph analysis of domestic research on cold chain logistics for fruits and vegetables based on CiteSpace

In recent years, the field of cold chain logistics for fruits and vegetables has emerged as a significant topic in academic research. This study adopts a bibliometric approach and utilizes the visual analysis tool CiteSpace to systematically investigate the progress of domestic research in this area. Based on 209 core articles retrieved from the CNKI (China National Knowledge Infrastructure) database from January 2007 to May 2024, the study constructs multi-dimensional knowledge graphsincluding discipline co-occurrence networks, author collaboration networks, and keyword timezone maps. The analysis reveals several key findings: there is a marked upward trend in the annual number of publications, research hotspots have evolved in phases, and core research areas concentrate on the optimization of cold chain logistics systems, innovations in preservation technologies for fruits and vegetables, and the construction of agricultural product logistics networks. It is worth noting that quality control of fruits and vegetables, along with related technological challenges, may become prominent directions for future research.
