基于文献计量的全产业链节粮减损研究态势分析OA

To systematically understand the development trends of grain saving and loss reduction in the whole industry chain at home and abroad,relevant literature in the field of grain saving and loss reduction in China National Knowledge Infrastructure(CNKI)and Web of Science(WOS)Core Collection databases from 2015 to 2025 was retrieved,and a total of 668 papers were obtained for visual analysis by using bibliometrics method and CiteSpace software.The publication trends,research subjects,hotspots evolution and research progress were investigated.The results showed that:1)Due to the impact of national policies,geopolitical conflicts and climatic factors,the number of published papers in both Chinese and English has significantly increased since 2020,demonstrating a marked upward trend.China ranks first in the number of relevant publications worldwide,followed by the United States,India,Brazil,France and the United Kingdom.2)The main research institutions include the University of Illinois System,China Agricultural University,Chinese Academy of Sciences,Chinese Academy of Agricultural Sciences,Federal University of Santa Maria and Swiss Federal Institutes of Technology Domain.The domestic research institutions have a high number of published papers,but their collaborative networks remain relatively sparse,whereas foreign research institutions exhibit stronger cooperative networks and significant influence.3)The evolution of research hotspots has progressed through three main temporal phases:early-stage focused on yield increase and loss reduction in production processes such as improved seed breeding,precise sowing,water and fertilizer conservation,precise pesticide application,disaster warning,and low-loss harvesting;mid-stage emphasized on loss reduction in supply chain links such as green warehousing,logistics transportation,moderate processing and quality improvement of grains,supervision of food waste,and reutilization of kitchen waste resources;later-stage concentrated on policy-driven interventions,promotional training and high-tech enabled loss reduction throughout the entire industry chain.Future research should integrate technological innovation,policy guidance and public participation,break through the limitations of single-point optimization in each link of the traditional industrial chain,and establish a new reduction paradigm that integrates"technology-process-system"collaboration.This multi-tiered approach will establish a comprehensive,coordinated technical system for grain saving and loss reduction throughout the whole industry chain.
