摘要
以cnki中1997~2019年与土地利用变化相关的文献为研究样本,运用CiteSpace作为文献可视化工具,对文献数据集的历年发文量、核心作者、科研单位、关键词及研究热点进行分析。结果表明:研究文献呈阶段性增长特征,经历了从快速增长到稳定增长的发展过程,文献数量总体呈现持续增长状态;研究土地利用变化的科研团队数量较多,但研究机构间的跨机构、跨地区、跨学科的合作较少,研究人员普遍呈分散化特征,学者间的联系并不紧密;土地利用变化研究的科研机构主要集中在高等科研院校;研究方向呈清晰化特征,当前我国关于在土地利用变化主要研究遥感、地理信息系统、构建模型、驱动力、气候变化等指标;主要研究区域是黄土高原黄土丘陵沟壑区以及农牧交错带等。
Base on the literature related to land use change in CNKI from 1997to 2019as research sample,CiteSpace was used as a document visualization tool to construct a knowledge map of land use change research and analyze the research hotspots in this field.The results showed that:the number of research literature was shown to be staged,experiencing a development process from rapid growth to stable growth,On the whole,it was showing a sustained growth state;Land use change was studied by many scientific research teams,but there was less intervinstitutional,inter-regional and inter-disciplinary cooperation among research institutions.Researchers were generally decentralized,and scholars were not closely related to each other;The research institutions for the study of land use change were mainly concentrated in institutions of higher college;The research direction was clearly defined,and it was concluded that remote sensing,geographic information system,construction model,driving force,climate change,etc.are taken as the main indicators in the research of land use change in China.The hilly and gully region of Loess Plateau and Farming-pastoral ecotone have been regarded as the main research area.
