基于文献计量分析的全球耕地撂荒研究综述

A Review of Global Farmland Abandonment Research Based on Bibliometric Analysis

耕地撂荒已经成为21世纪以来备受关注的全球性问题, 耕撂荒严重影响着粮食安全和粮食产量, 为了客观揭示当前撂荒领域问题的特点, 本文基于Web of Science的核心数据库, 系统筛选了2009—2023年期间耕地撂荒领域的研究型和综述性论文。[方法]利用Bibliometrix和Biblioshiny软件包进行计量分析。[结果]结果表明: (1) 2009—2023年期间耕地撂荒领域的发文量持续增加, 从文章数量的增长趋势来看, 大体可分为三个阶段: 2009—2012年为发育萌芽期, 2013—2017年为增长期, 2018—2023年为高产期。 (2) 《Land》期刊的发文数、被引用次数和影响力是最高的, 其次是《Sustainability》期刊。同时《Land》自2016年开始发表撂荒领域的论文, 增长速度位列各期刊第一; (3) 在此期间共有88个国家在该领域产出论文, 其中发文量排名前十的国家分别是: 中国、西班牙、意大利、德国、美国、波兰、尼德兰、日本、瑞士、法国。其中, 瑞士、德国、尼德兰处于合作的中心, 中国与美国、瑞士与德国的合作较为密切, 中国在合作发文总量上并不突出, 德国学者较为注重科研合作。 (4) 对于耕地撂荒领域研究的关键词可以概括为四类: 第一类是有关土壤侵蚀的耕地撂荒; 第二类注重撂荒影响机制的探究; 第三类主要分析研究方法和手段, 以及与多学科的交叉研究; 第四类聚焦于植被覆盖和土地退化方面。[结论]分析了耕地撂荒当下和未来的研究趋势, 影响和驱动机制为研究热点, 遥感技术的应用也应进一步加强, 如空间识别、信息提取和多尺度模拟监测等。要在注重科研合作的基础上提出有效的应对策略, 保障粮食安全, 促进人与自然的和谐共生。

Farmland abandonment has become a global issue of significant concern since the beginning of the 21st century, severely impacting food security and grain production. To objectively reveal the characteristics of current research in this field, this study systematically selected research and review papers on farmland abandonment published between 2009 and 2023 from the core collection of the Web of Science database. [Methods] Bibliometric analysis was conducted using the Bibliometrix and Biblioshiny software packages. [Results] The results indicate that: (1) The number of publications in the field of farmland abandonment increased continuously from 2009 to 2023. Based on the growth trend, the period can be roughly divided into three stages: an embryonic stage (2009-2012) , a growth stage (2013-2017) , and a high-output stage (2018- 2023) . (2) The journal Land had the highest number of publications, citations, and influence, followed by Sustainability. Furthermore, Land began publishing papers on abandonment in 2016 and has the fastest growth rate among all journals. (3) During this period, 88 countries contributed papers to this field. The top ten countries by publication volume were: China, Spain, Italy, Germany, the USA, Poland, the Netherlands, Japan, Switzerland, and France. Switzerland, Germany, and the Netherlands were at the center of collaborative networks. Collaboration between China and the USA, and between Switzerland and Germany, was relatively close. China's total number of collaborative publications was not particularly prominent, while German scholars placed greater emphasis on research collaboration. (4) Keywords in farmland abandonment research can be categorized into four groups: the first relates to farmland abandonment concerning soil erosion; the second focuses on exploring the influencing mechanisms and driving forces of abandonment; the third primarily analyzes research methods and techniques, along with interdisciplinary studies; and the fourth concentrates on vegetation cover and land degradation. [Conclusions] The study analyzes current and future research trends in farmland abandonment. Impact and driving mechanisms remain research hotspots. The application of remote sensing technologies, such as spatial identification, information extraction, and multi-scale simulation and monitoring, should be further strengthened. It is essential to propose effective coping strategies based on enhanced research collaboration to ensure food security and promote the harmonious coexistence of humans and nature.
