【摘要】：论文通过收集"基本农田"为关键词的537篇检索文献,建立关键词共现关系聚类图谱与时区图谱,以Citespace可视化分析法分析近30 a(1986—2015年)中国基本农田领域研究的发展态势。研究结果表明:1)基本农田领域的研究聚类集中在基本农田保护、评价、划定以及建设等4个领域,研究内容与方法侧重点不同;2)基本农田研究内涵及内容体系丰富,具有明显的时代性特征,并且具有明显的地域差异性和时间变异性;3)基本农田研究还存在一定的共性问题,一是基本农田划定与评价指标体系过于笼统,评价体系缺乏协调性,二是缺少各级别的基金资助与支持。研究建议:基本农田评价与划定标准体系要考虑区域特征与需求;基本农田研究要适应土地利用规划及土地整治等国家战略要求;同时,基本农田研究应是一项科学问题,要发展成为国家自然基金等资助的重要检索关键词与申报领域。
[Abstract]:Based on the collection of 537 retrieval documents on "basic farmland", the cluster map and time zone map of cooccurrence relationship were established, and the development trend of basic farmland research in China from 1986 to 2015 was analyzed by Citespace visual analysis method. The results show that the research cluster in the field of basic farmland is concentrated in the four fields of basic farmland protection, evaluation, delineation and construction, and the research contents and methods are different. 2) the research contents and content system of basic farmland research are rich. There are some common problems in basic farmland research. One is that the index system of basic farmland demarcation and evaluation is too general and the evaluation system lacks coordination. Second, the lack of various levels of fund support and support. The research suggests that the basic farmland evaluation and demarcation standard system should take into account the regional characteristics and needs; the basic farmland research should adapt to the national strategic requirements such as land use planning and land regulation; at the same time, the basic farmland research should be a scientific issue. To develop into the National Fund for Nature and other important search keywords and applications.
