基于CiteSpace的耕地资源安全评价研究热点与趋势分析

Analysis of Research Hotspots and Trends in the Security Evaluation of Cultivated Land Resources Based on CiteSpace

耕地资源安全评价是衡量区域内耕地保护状况与农业绿色发展的关键问题,但耕地资源安全评价研究内容宽泛、纷繁复杂,因而需要对其进行较为系统的归纳整理。基于此,利用CiteSpace文献计量分析工具,构建国内外2001—2020年耕地资源安全评价知识图谱。结果表明:发文量逐年上升,但是重要的作者之间的合作还比较少,各个机构之间联系强度较弱;大尺度范围的行政区域是耕地资源安全评价的主要范围,耕地质量、生态安全评价成为当前研究关注的热点,定量与综合分析成为耕地资源安全评价的主要趋势。最后,提出了未来的研究趋势,即耕地资源安全评价的研究范围趋于多样化、研究内容趋于综合性、研究方法趋于多样性。

Cultivated land resource security evaluation is a key issue to measure the protection of cultivated land and agricultural green development in the region. However, the research content of cultivated land resource security evaluation is wide and complicated, so it needs to be summarized and sorted out systematically. Based on this, a knowledge map of cultivated land resource security assessment from 2001 to 2020 at home and abroad was constructed by using the CiteSpace bibliometric analysis tool. The results showed that: The amount of publications is increasing year by year, but the cooperation between important authors is still relatively small, and the strength of contact between various institutions is weak. The large-scale administrative area is the main scope of farmland resource security assessment, farmland quality and ecological security assessment have become the focus of current research, and the quantitative and comprehensive analysis has become the main trend of farmland resource security assessment. Finally, the research trends in the future were put forward, that is, the research scope of farmland resource security evaluation will tend to be diversified, the research content will tend to be comprehensive, and the research methods will tend to be diversified.
