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