中国耕地非粮化研究进展

Progress of research on the non-grain of cultivated land in China

依托中国知网(CNKI)数据库,采用文献分析、数据统计、比较分析和CiteSpace可视化分析对中国耕地非粮化的现状进行了系统的整理与归纳,并对其今后的发展趋势与重点进行了预测。结果表明:研究趋势上,近年来,耕地非粮化研究进入高发期。非粮化、粮食安全、非农化、土地流转、耕地流转、耕地保护这些领域是近年耕地非粮化研究的热点问题。研究内容上,概念较为统一,表征却不尽相同,其成因分析、外部效应和应对措施已较为丰富。今后要深入对耕地非粮化表征的研究,创新其测算方式;加强跨学科交叉融合和多视角分析研究,向多维度统筹、多层次并重的系统科学视角转变,与国家重大战略协同推进,为缓解中国耕地非粮化提供决策参考。

Relying on the database of China Knowledge Network(CNKI),literature analysis,data statistics,comparative analysis and CiteSpace visual analysis were used to systematically organize and summarize the current situation of"non-grain"in China,and to predict its future development trend and focus.The results showed that,in terms of research trends,the research on non-grain of cultivated land has entered into a period of high incidence in recent years.The areas of non-grain food security,non-farming,land transfer,arable land transfer,and arable land protection are the hot issues in the research of cultivated land non-grain in recent years.In terms of research content,the concept was relatively uniform,but the characterization was not the same,and the analysis of its causes,external effects and countermeasures have been relatively abundant.In the future,it is necessary to deepen the research on the characterization of arable land non-grainization and innovate the way of its measurement;strengthen the interdisciplinary cross-fertilisation and multi-perspective analysis and research,and shift to the systematic scientific perspective of multi-dimensional integration and multi-level concurrent focus,so as to synergise with the national major strategies,and to provide the decision-making references to alleviate China's non-grain of cultivated land.
