科研動態(tài)

為探究我國動物疫病傳播風險評估的研究熱點及趨勢，以2000—2019年“中國知網”（CNKI）數據庫收錄的348篇動物疫病風險評估相關文獻為研究對象，利用CiteSpace軟件對文獻進行時空分析和內容分析。時空分析顯示，這20年間動物疫病風險評估文獻數量呈現(xiàn)從少到多再減少的動態(tài)過程，各大研究機構合作較少。內容分析顯示，研究熱點主要涉及“風險評估”“風險分析”和“動物疫病防控”等方面。提示研究機構應加大動物疫病風險評估研究力度，加強各大研究機構間的合作，推進動物疫病風險評估的研究、分析、監(jiān)管，完善預警機制，進一步提升我國動物疫病防控水平。本研究可為深化動物疫病風險評估研究、實踐和預警提供參考。

Research Hotspots and Trends of Animal Disease Risk Assessment in China According to Visual Analysis Based on Citespace

In order to explore the research hotspots and trends of animal disease risk assessment in China，348 articles concerning such risk assessment registered in the database of CNKI during 2000 to 2019 were retrieved and analyzed by CiteSpace software based on their time and space as well as contents. It was shown that，by the temporal and spatial analysis，the number of literature on risk assessment went through a dynamic process from emerging to increasing then to decreasing in the past 20 years，and fewer major institutes cooperated with each others. The contents of the literature were analyzed，it was found that“risk assessment”，“risk analysis”and“animal disease prevention and control”were the research hotspots. Therefore，institutes should strengthen their inputs in animal disease risk assessment，and increase cooperation with each others，so as to push forward the study，analysis and supervision concerning risk assessment，improve early warning system，and to further upgrade the control level of animal diseases. Some references were provided to further the study and practice of risk assessment and early warning.
