农业可持续发展研究热点与趋势——基于文献计量的可视化分析

农业直接关系到粮食安全和农户收入,既高度依赖于资源环境又反作用于资源环境.农业可持续发展是实现可持续发展目标的关键.通过CiteSpace对Web of Science和中国知网在2000—2019年发表的关于农业可持续发展评价的1174篇英文和1043篇中文文章进行文献计量分析,总结出农业可持续发展的研究前沿、热点和趋势,以期为农业可持续发展研究和决策管理提供参考.结果 表明:农业可持续发展的研究前沿聚焦在食物系统弹性与粮食安全、农业生态集约化与可持续集约化、都市农业与农业多功能性、农业生态系统服务权衡与协同4个方面.研究热点主要关注气候变化对农业系统的影响及其适应性管理、农业生态系统服务管理、农业活动的环境影响和农业系统可持续性综合评价.建议在今后的研究中进一步解析"气候-土地-水-能源-粮食"耦合机制,系统开展农业生态系统的"影响因素-作用机理-调控方法"研究.

Hotspots and trends of agriculture sustainable development: Visualization analysis based on bibliometrics

Agriculture is directly related to food security, which is highly dependent on and significantly impacts resources and the environment. Sustainable agriculture development is key to achieving the sustainable development goals. Frontiers, hot topics, and trends of sustainable agriculture development were summarized for scientific research and decision-making by CiteSpace based on 1 174 papers published in the Web of Science and 1 043 papers published in China National Knowledge Infrastructure from 2000 to 2019. Results showed that the frontiers were mainly focused on"food system resilience and food security", "ecological intensification and sustainable intensification", "agricultural muti-functionality and urban agriculture", and"trade-offs and synergies of ecosystem services in agroecosystem". Hotspots included how climate change impacts agricultural systems and its adaptive management, ecosystem services management in agro-ecosystems, and the environmental impact assessment of agricultural activities and integrated sustainability assessment of an agricultural system. It is suggested that the coupling mechanism of the"climate-land-water-energy-food"nexus should be further analyzed, and"influencing factors-action mechanisms-regulation methods"of agro-ecosystem should be systematically studied in the future.
