[目的]蓝色食物已经成为全球可持续发展目标下人类营养健康和粮食安全的重要解决方案。因其营养健康性和环境友好性，正在成为食物系统转型升级的关注焦点。通过全面梳理蓝色食物发展脉络与研究动态，可进一步归纳其热点议题和未来发展方向。[方法]本文以"Web of Science 核心合集"(1985-2023年)为数据源，基于CiteSpace软件对蓝色食物的相关研究成果进行分析，并探讨地理学视角下蓝色食物的研究框架和未来的关键议题。[结果]①已有研究总体经历了初始稳步增长、中期缓慢增长、近期快速发展3个阶段，研究领域广，研究机构多，但存在理论建构不足，国际交流与合作薄弱等问题。②研究持续关注水产养殖、食品安全检测、居民消费等方面，近年热点议题更加注重人地关系和可持续食物系统的构建，主要围绕蓝色食物的营养健康价值、资源环境效应、社会经济价值、需求与消费、饮食建议等方面。[结论]通过对蓝色食物研究进展的分析以及地理学视角下蓝色食物研究框架体系的构建，本文认为，未来需要重点关注不同场景和群体的蓝色食物消费研究、蓝色食物生产和消费的时空分异研究、蓝色食物环境效应的多尺度评估及作用机理分析、蓝色食物系统的稳定性及未来变化应对、蓝色食物消费结构的多目标优化研究等关键议题，推动中国蓝色食物研究的理论提升和实践创新。
Progress and prospect of blue food research:Analysis based on"Web of Science"literature
[Objective]Blue food has become an important solution for human nutrition,health,and food security under the global sustainable development goals.Because of its nutritional health and environmental potential,it is becoming the focus of the transformation and upgrading of the food system.By comprehensively sorting out the development context and research trends of blue food,its hot topics and future development direction can be further summarized.[Methods]Based on the"Web of Science Core Collection(1985-2023)"as the data source,this study analyzed the relevant research results of blue food based on CiteSpace software,and discussed the research framework and future key issues of blue food from the perspective of geography.[Results]The findings are as follows:(1)Existing research has experienced three stages of steady growth at the initial stage,slow growth in the middle stage and rapid development in the recent period.The re-search fields are broad and there are numerous research institutions,but there exist issues such as insufficient theoretical construction and weak international exchanges and cooperation.(2)Existing studies continue to pay attention to aquaculture,food safety testing,consumer consumption,etc.In recent years,hot topics have paid more attention to human-land relationship and the construction of sustainable food systems,focusing on the nutrition and health value,resource and environmental effects,social and economic value,demand and consumption,and dietary recommendations of blue food.[Conclusion]By analyzing the progress of blue food research and constructing a framework for blue food studies from a geographical perspective,this paper suggests that future efforts should focus on the study of blue food consumption in different scenarios and groups,spatial and temporal differentiation of blue food production and consumption,multi-scale assessment and mechanism analysis of the environmental effects of blue food,the stability of blue food system and the re-sponse to future changes,and the multi-objective optimization of blue food consumption structure,so as to promote the theoretical improvement and practical innovation of blue food research in China.
