摘要
基于Web of Science(SCI)和知网(CNKI)数据库中以耕地撂荒为研究主题的文献数据,借助CiteSpace软件对1990—2021年耕地撂荒领域的研究论文进行数据挖掘和定量分析(数据更新时间为2022年3月20日),对国内外耕地撂荒领域的论文数量、引文数量、主要作者、相关学术期刊和关键词进行系统梳理和对比研究,进而探讨中国耕地撂荒未来的研究方向。结果表明:(1)在过去近32 a,关于耕地撂荒的论文数量有所增加,国内外学者对耕地撂荒的关注不尽相同,国内外耕地撂荒研究发展历程存在差异,各阶段的研究重点不尽相同。(2)耕地撂荒、撂荒地、土地利用、景观、碳汇、土壤退化是近年来耕地撂荒领域的高频关键词。(3)国内耕地撂荒领域的研究热点主要集中在耕地撂荒的形成原因、影响因素等研究方向,国外的研究更多是研究群落多样性和农田景观动态等方面。(4)国内外学者的研究大多集中于小尺度上耕地撂荒的成因、机制、影响、建议等方面,在大尺度上的研究较少,就遥感、大数据、网络数据模拟、动态监测等方面的研究仍然缺乏。本研究建议以后的研究应基于全球视野,进一步系统深入地探索耕地撂荒内容、成因、演变机理和影响,同时充分利用人工智能技术检测和获取耕地撂荒的时空动态,尝试林草一体化高质量发展等农业模式,以便为治理撂荒制定合理、有效的措施。
Based on the literature in the databases of the Web of Science(SCI)and CNKI,CiteSpace is used to conduct data mining and quantitative analysis of the research papers in farmland abandonment from 1990 to 2021(data updating time:March 20,2022).The number of papers and citations,main authors,relevant academic journals,and keywords regarding cultivated land abandonment in China and abroad are systematically sorted out and studied comparatively.The future research direction of cultivated land abandonment in China is then discussed.The following results were obtained:(1)The number of papers regarding cultivated land abandonment has increased in the past 32 years.Scholars in China and abroad pay different attention to the field.There are differences in the development of the research on cultivated land abandonment in China and abroad,and the research focus of each stage is different.(2)Abandoned cultivated land,abandoned land,land use,landscape,carbon sink,and soil degradation are high-frequency keywords of cultivated land abandonment in recent years.(3)The research hot spots of the field in China mainly focus on the causes and influencing factors of cultivated land abandonment,while foreign research is more focused on community diversity and farmland landscape dynamics.(4)The research of Chinese and foreign scholars mostly focus on the causes,mechanism,impacts,and suggestions of farmland abandonment on a small scale,and there are few large-scale studies,including those on remote sensing,big data,network data simulation,and dynamic monitoring,among others.This study suggests that future research should be based on a global perspective.In addition,this study explores the content,causes,evolution mechanism,and impact of cultivated land abandonment systematically.Meanwhile,it should make full use of AI technology to detect and obtain the temporal and spatial dynamics of cultivated land abandonment and try to adopt the agricultural models such as the high-quality development of forest-grass integration to formulate reasonable and effective measures to deal with farmland abandonment.
