中国耕地利用效率研究综述与展望

Review and prospect of cultivated land use efficiency research in China

中国现有耕地数量有限、耕地后备资源严重不足,提高耕地利用效率是保障中国粮食安全的必要条件之一。为综合展现近年来中国耕地利用效率的相关研究现状和发展趋势,系统回顾现有研究展望未来发展。以中国学术期刊全文数据库(CNKI)、Web of Science(WoS)核心期刊为数据源,以2002—2022年208篇研究论文为研究对象,通过文献计量分析法,运用CiteSpace等文献计量可视化软件进行可视化图谱分析。研究发现,中国目前在耕地利用效率上的研究,形成了以DEA方法为主体,综合运用Malmquist指数、相关参数模型为测算框架的耕地利用效率测度体系;以GIS技术、ESDA等时空差异分析方法;以Tobit计量回归模型为主的耕地利用效率影响因素评价体系。对比国内外相关研究发现,中国现阶段相关研究主要从效率测算角度出发,探寻耕地利用效率的提升路径,而国外相关研究主要从可持续发展视角出发,力图寻找更合理的耕作制度与农业系统。

The number of cultivated land in China is limited,and the reserve resources of cultivated land are seriously insufficient.Improving the utilization efficiency of cultivated land is one of the necessary conditions to ensure food security in China.In order to comprehensively show the research status and development trend of cultivated land use efficiency in China in recent years,this study systematically reviews the existing research and looks forward to the future development.This paper takes China Academic Journal Full-text Database(CNKI)and Web of Science(WoS)Core Journals as data sources,and 208 research papers from 2002 to 2022 as the research object.Through bibliometric analysis,CiteSpace and other bibliometric visualization software are used to carry out visual map analysis.The study found that China's current research on cultivated land use efficiency has formed a cultivated land use efficiency measurement system with DEA method as the main body,comprehensive use of Malmquist index and related parameter model as the measurement framework;GIS technology,ESDA and other spatial and temporal difference analysis methods;and the evaluation system of influencing factors of cultivated land use efficiency based on Tobit econometric regression model.Compared with the relevant research at home and abroad,it is found that the relevant research at the present stage in China mainly explores the improvement path of cultivated land use efficiency from the perspective of efficiency measurement,while the foreign research mainly tries to find a more reasonable farming system and agriculture system from the perspective of sustainable development.
