Research Status And Hotspot Analysis Of Agricultural Informatization Based On Bibliometrics

Informatization is the trend of world development and one of the important forces of economic development.As an important part of informatization,agricultural informatization has been paid increasingly attention by the state,and its related theoretical research and practical summary have become the focus of academic circles.This paper utilizes the literature on the field of agricultural informatization in the China Academic Journals full-text database(CNKI)and the Web of Science foreign language database as the data source,according to the keywords,the year output,the author ’s name,the author’s organization,the issuing organization,etc.,analyzes the current research status,domestic and foreign research hot-spots and research trends of agricultural informatization by the method of bibliometric,co-word analysis and cluster analysis.The main findings are as follows:(1)Analysis of the overall distribution characteristics of agricultural informatization literature based on bibliometrics.This paper uses the bibliometric method to qualitatively analyze the time distribution,core authors and source journals of domestic and foreign agricultural informatization fields.From the perspective of the distribution of the literature,the number of Chinese literature has experienced three stages: relatively few publications in the early period,rapid increase in the medium term,and relatively constant phase in the later period.The number of foreign literatures has shown a steady upward trend.It is found that Hu Xuwei,Xu Shiwei,Li Daoliang,Guo Zuoyu,Liu Yueqi,Mei Fangquan,etc.are the core authors of the domestic agricultural informatization research field,meanwhile,Anderson,Martha C;Fukuda,Shinji;Ouyang,Wei;Luo,Zhong kui are the core author of the field of international agricultural information research by investigating of the core authors.Hence which is found simply that the vast majority of Chinese literature comes from the journals associated the scientific and technological management,agriculture and computer science via the analysis of the domestic literature sources.The foreign literature are mainly from Science of the Total Environment,PLOS ONE,Computers and Electronics in Agriculture,Agriculture Ecosystems & Environment.(2)Analysis of hotspots in the field of agricultural informationization at home and abroad based on co-word clustering analysis.This paper extracts and frequency statistics of literature keywords,and uses the co-word analysis and cluster analysis of high-frequency keywords to analyze the research hotspots in the field of agricultural informationization at home and abroad.Result shows that the research hotspots in the field of agricultural informationization in China are mainly agricultural(rural)informationization,information technology,the three rural issues,precision agriculture,agricultural information services,modern agriculture,new rural construction,agricultural information resources.The research hotspots in the field of international agricultural informatization are mainly five aspects of precision agriculture,geographic information system,land use,climate change and biodiversity.(3)Visual analysis of agricultural informationization research trends.This paper selects CNKI core journal literature,and uses the co-word analysis and cluster analysis of keywords to discuss the research trend of agricultural informatization in China.The results show that the research focus of agricultural informatization has experienced changes from agricultural information resources,agricultural information work,digital agriculture,agricultural websites,e-commerce,to smart agriculture,precision agriculture,and modern agriculture.
