基于CiteSpace的土地利用转型研究发展定量分析

Quantitative Analysis of Land Use Transformation Based on CiteSpace

利用Web of Science和CNKI数据库,运用科学计量CiteSpace软件,从研究发展历程、作者合作网络分析、机构合作网络分析、国家合作网络分析、研究热点主题5个维度对国际土地利用转型发展进行定量分析。结果表明,土地利用转型的发文数量逐年上升,内容涉及土地利用覆被变化、生态服务功能、耕地保护、城市扩张、乡村转型发展以及粮食安全等;在合作网络中,中国科学院和中国科学院大学在国际上关于土地利用转型研究位列第1梯队,美国与中国成为土地利用转型研究领域的主要国家;龙花楼等3个研究团队发文数量和被引次数名列前茅;土地利用转型热点主题聚焦于土地利用/覆被变化、土地利用转型效应和土地利用转型与生态服务、粮食安全3个方面。

Using Web of Science,CNKI database and scientific metrology CiteSpace software,quantitative analysis of international land use transformation and development were carried out from five dimensions of research development history,author cooperation network analysis,institutional cooperation network analysis,national cooperation network analysis and research hot topics.The results showed that the number of publications on land use transformation had been increasing year by year,including changes in land use and cover,ecological service functions,cultivated land protection,urban expansion,rural transformation and development,and food security.The Chinese Academy of Sciences and the University of Chinese Academy of Sciences ranked the first echelon of international research on land-use transition,the United States and China became the two main countries in the field of land-use transition research,while Long Hualou and other three research teams were among the top in the number of articles as well as the citations.The hot topics of land-use transition focused on three aspects of land use/cover change,land use transition effects,land-use transition and ecological services,and food security.
