摘要:

目的 农业生态效率综合考虑经济效益和环境效益，是农业绿色发展的表征指标之一。通过梳理中国农业生态效率的研究热点与趋势，为中国农业生态效率和农业可持续发展的研究提供参考。方法 文章以知网数据库为基础，搜集整理1981—2022年中国农业生态效率领域的相关文献共433篇，从发文量、作者、机构基金和关键词方面进行研究。通过CiteSpace对作者共线、关键词共线、关键词聚类等进行分析，绘制可视化图谱。结果 （1）2011年后此研究领域的发文量开始增加，研究热点由关注农业环境理念向计量方法和影响因素转变，基础理论、评价测度和效率应用共同构成该领域的研究主题。（2）目前还存在学者间合作较少，研究相对独立；研究对象多为全国或省级层面，对县乡级研究有待深入；评价方法上较少使用复合模型；研究主题有待创新等问题。结论 在资源与环境双重压力下，农业生态效率的研究已成为现代农业绿色化发展的重要组成部分。

Abstract:

Agricultural eco-efficiency is one of the characteristic indicators for the green development of the agriculture, which comprehensively considers the economic returns and environmental benefits. By sorting out the research hotspots and trends of agricultural eco-efficiency in China, this paper provides reference for the research of eco-efficiency and sustainable development of agriculture. Based on the CNKI database, this paper collected a total of 433 relevant literatures in the field of agricultural eco-efficiency in China from 1981 to 2022, and conducted the research from the perspectives of publications, authors, institutions, funds and keywords. This paper also drew visualizing maps through the visualization software CiteSpace to analyze the author co-occurrence, the keyword co-occurrence, the keyword clustering and others aspects. The results were showed as follows. The number of publications in the research field of agricultural eco-efficiency had increased since 2011, and the research hotspots changed from the concept of agricultural environment to measuring methods and influencing factors, and the basic theory, evaluation and efficiency application together constituted the research themes. However, the current researches had the following issues. There was still less cooperation among scholars and relatively independent research. The research objects were mostly at the national or provincial level, and the studies on the county and township level needed to be deepened. The composite model was rarely used in the evaluation of agricultural eco-efficiency and the research topics needed to be innovated. Therefore, under the double pressure of resources and environment, the research of agricultural eco-efficiency becomes an important part of the green development of modern agriculture.
