The Retrospect And Prospect Of Agricultural Inforamtionization Research In China Based On Knowledge Map

With the advent of the information society, the state paied more and more attention on Agricultural Informationization, many scholars began to focus on Agricultural informationization. In this paper, using Citespace II, the author gets data sources from the items of’Agricultural Informationization,"Doctoral&Master degree’s dissertations, and the essays on the Agricultural Informationization in journals. I made a knowledge map of the contents of Agricultural Informationization, hoping that this paper could conduct a comprehensive analysis of the history and current situation of China’s Agricultural Informationization Research, and future research trends were discussed.The main contents include three parts:The first part, characterization of two types of data sources in the form of characteristic analysis. By the time Dissertation distribution analysis, we find that the number of "Agricultural Informationization" as the topic of the general Dissertation showed a gradual upward trend; Through the agency Dissertation Authors distribution analysis, can be found mostly in the agriculture category of universities and the comprehensive University. By the time the distribution of journal articles were analyzed and found agricultural information also showed a number of journal articles published curve growth trend; By Papers Authors are analyzed and found such as Liu Xiaoping, Liu liwei, Lu lina, Chen xilong, Jia shangang were Agricultural Informationization research core Authors of our country; Through the analysis of journal articles Authors institutions, found that the vast majority belong to the agricultural colleges, comprehensive universities, libraries and research institutions; Source journals were analyzed and found agricultural information scattered distribution of research papers, mainly in the agricultural journals and Technology Management is closely related to agriculture, information, computers, and intelligence disciplines, such as economics journals through. The second part, features two types of data sources to characterize the content analysis. High-frequency words by statistical analysis and knowledge maps were drawn on the "agricultural information," the research focused on the content of Dissertation journal articles. By analyzing, found that the Dissertation focused on the agriculture informationization,rural areas, agriculture, farmers, agricultural information, agriculture informationization construction, geographic information systems (GIS), agricultural expert systems, agricultural information services, information technology, information services, modernization of agriculture, modern agriculture, commerce, agricultural extension and other fields. Journals focused on agriculture informationization, agriculture informationization construction, agriculture information services, information technology, agricultural modernization, information services, information resources, rural areas, agriculture,farmers, modern agriculture, precision agriculture and rural incomes, agricultural information network, the agricultural sector, agricultural industrialization, agricultural products, agricultural development, and production and other fields. On this basis, using the content analyzing method based on word frequency and Citespace II, come to the conclusion that there is coherence among the two dimension data resources’ research focuses:agriculture informationization, rural issues, information resources, information services, information resources, new rural construction, information technology, geographic information systems, agricultural expert system, modernization of agriculture, modern agriculture, agricultural production, agricultural industrialization. At last, the time evolution of agricultural research information for1989-1999,2000-2005,2006and2007-2013, respectively detailed study of the three time periods of agricultural informationization research focus and priorities, as well as changes.The third part, the use of mutation analysis CiteSpaceⅡ studied China’s agricultural frontier areas of information technology, including cloud computing, information service system, agricultural information services and agricultural promotion. Future studies of agricultural information will show the characteristics of automation, modernization and diversification.
