近20年我国粮食安全研究的进展与展望——基于CiteSpace的可视化分析

Progress and Prospect of Domestic Food Security Research in the Past 20 Years:Visual Analysis Based on CiteSpace

粮食安全已成为国家安全的重要议题,梳理其研究进展对后续研究具有重要指导意义。基于CiteSpace可视化分析软件,筛选CNKI数据库中与粮食安全相关的文献进行梳理,揭示粮食安全研究的分布特征、知识结构和发展进程。结果显示,该主题研究的核心作者相对较为集中,合作呈大分散、小聚集格局,不同团队研究角度和方法呈现多样化,主要研究机构是农业类大学或中国科学院,各研究机构之间形成了部分合作团体。研究关键词多元化,热度较高的主题分别为耕地保护与粮食安全、粮食生产与供求、城镇化与乡村振兴、气候变化与粮食安全。研究热点具有政策导向性,且时效性明显,退耕还林、粮食供求、粮食危机、城镇化等分别是不同时期的研究热点。研究进程主要分为初步探索—拓展深化—成熟发展3个阶段。未来粮食安全领域可能深入研究数字农业的发展、探索作物生产减排固碳路径、深化耕地“非粮化”问题以及探析“大食物观”新发展理念。

Food security has become an important issue of national security and reviewing its research progress has important guiding significance for subsequent research.Based on the CiteSpace visual analysis software,this paper screens and analyzes the literature related to food security in the CNKI database to reveal the distribution characteristics,knowledge structure and development process of food security research.The results show that the core authors of this research topic are relatively concentrated,with a pattern of large dispersion and small aggregation in cooperation;the research perspectives and methods of different teams are diversified.The main research institutions are agricultural universities or Chinese Academy of Sciences,and some cooperation groups have been formed among the research institutions.The research keywords are diversified,and the topics with higher popularity are cultivated land protection and food security,food production and supply-demand,urbanization and rural revitalization,climate change and food security.The research hotspots are policy-oriented and timely,such as returning farmland to forest,food supply-demand,food crisis and urbanization,which are the research hotspots in different periods respectively.The research process is mainly divided into three stages:preliminary exploration,expansion and deepening,and mature development.In the future,the field of food security may further study the development of digital agriculture,explore the path of emission reduction and carbon sequestration in crop production,deepen the issue of“non-grain”cultivated land,and explore the new development concept of“an all-encompassing approach to food”.
