基于CiteSpace软件国内外撂荒地研究进展与述评

基于Web of Science(WOS)和CNKI数据库中以撂荒地为研究主题的文献数据，借助CiteSpace软件对国内外撂荒地研究学科、作者、内容、热点、进程进行梳理，进而对撂荒地成因、机制、影响进行分析。了解国内外撂荒地研究历程和研究现状，并总结遏制土地撂荒的具体措施和办法，期待为中国撂荒地研究提供指引。结果表明：① 国内外学者对撂荒耕地的关注不尽相同，国外学者多研究撂荒地的形成机制，国内学者则侧重揭示耕地撂荒现象。农用地撂荒是国外的研究热点，撂荒政策、模型模拟和遥感技术运用是国内的研究热点。② 国内外撂荒地研究的发展历程有所差别，各阶段呈现出不同的研究特征。③ 撂荒地研究中国内外学者在成因、机制、影响、举措等方面有共识。建议学者采用地理空间大数据、流数据、遥感影像数据等，对撂荒地的时空模拟、趋势推演、风险评估等开展研究；探寻不同资源禀赋和社会经济背景下撂荒的驱动和演变规律，总结演化过程；提出自然-社会-经济等科学化、系统化的研究方法，丰富研究内容和成果；并开展村镇级小尺度案例研究，为理论深化和方法创新提供支撑，进而为小尺度区域的撂荒地生态修复与治理提供理论支撑和案例借鉴。

Research Progress and Review of Abandoned Land Based on CiteSpace

Based on the literature data of abandoned land in WOS and CNKI databases, this article used CiteSpace software to sort out the research subjects, authors, contents, hotspots and progress of abandoned land at home and abroad, and then analyzed the causes, mechanisms and impacts of abandoned land. To understand the research process and research status of abandoned land at home and abroad, and summarize the specific measures and methods to curb land abandonment, expecting to provide guidance for the study of abandoned land in China. The results showed that: 1) Scholars at home and abroad paid different attention to farmland abandonment. Foreign scholars mostly studied the formation mechanism of farmland abandonment, while domestic scholars focused on revealing the phenomenon of farmland abandonment. Abandonment of agricultural land is a research hotspot abroad, while abandonment policy, model simulation and application of remote sensing technology are domestic research hotspots. 2) The development process of abandoned land research is different at home and abroad, and each stage presents different research characteristics. 3) There is a consensus among Chinese and foreign scholars on the causes, mechanisms, impacts and measures of abandoned land. It is suggested that Chinese scholars use geospatial big data, streaming data and remote sensing image data to conduct research on spatio-temporal simulation, trend deduction and risk assessment of abandoned land. Furthermore, the driving and evolution laws of abandonment under different resource endowments and socio-economic backgrounds were explored and the evolutionary process was summarized. Scientific and systematic research methods on nature, society and economy have been put forward to enrich the research contents and achievements. Small-scale case studies at the village level can provide support for theoretical deepening and method innovation, and further provide theoretical support and case reference for ecological restoration and management of abandoned land in small-scale regions.
