基于CiteSpace国内景观基因的研究热点、进程及展望解析

Analysis of Research Hot Spots,Processes and Prospects of Domestic Landscape Genetics based on CiteSpace

景观基因是决定地方空间发展变化的内生动因,它代表着景观的物质环境与精神形制的双重内核,对研究地方空间发展与复兴具有重要意义。随着学界对中国景观基因的渗透研究,涌现出大量的相关研究文献,为了更好地把握其研究动向,文章搜集近20年CNKI数据库中与景观基因研究主题相关文献作为研究对象,利用CiteSpace可视化软件制作知识图谱,对我国景观基因关键词共现、聚类、突变图谱以及时间线与时区图谱的变化进行理论研究。研究表明:(1)景观基因的研究进程分为理论描述、论证机理、规律挖掘、拓展应用4个阶段;(2)随着研究技术增长与社会空间发展,景观基因研究热点的突变契合当下人居环境发展所面临的问题;(3)景观基因的关注点从二维图谱框架发展到了三维时空场景,并尝试利用数字技术更加客观地进行量化研究。

Landscape gene is the internal dynamic factor that determines the development and change of local space,which represents the dual kernel of physical environment and spiritual form of landscape,and is of great significance to the study of local spatial development and revitalization.With the penetration research of Chinese landscape genes in academia,a large amount of related research literature emerges,in order to better grasp its research trend,this paper collects the literature related to the research topic of landscape genes in the CNKI database in the past 20 years as the research object,and uses the CiteSpace visualization software to produce a knowledge map to analyze the keyword co-occurrence,clustering,mutation mapping of China's landscape genes,as well as the time-line and changes of time zone mapping for theoretical research.The study shows that(1)the research process of landscape genes is divided into four stages:theoretical description,argumentation mechanism,law mining,and expansion application.(2)With the growth of research technology and the development of social space,the hotspots of landscape genetics research change to fit the current problems facing the development of human environment.(3)The focus of landscape genetics has developed from a two-dimensional mapping framework to a three-dimensional spatial and temporal scene,and attempts to utilize digital technology to conduct quantitative research more objectively.
