科研动态

为探究我国动物疫病传播风险评估的研究热点及趋势，以2000—2019年“中国知网”（CNKI）数据库收录的348篇动物疫病风险评估相关文献为研究对象，利用CiteSpace软件对文献进行时空分析和内容分析。时空分析显示，这20年间动物疫病风险评估文献数量呈现从少到多再减少的动态过程，各大研究机构合作较少。内容分析显示，研究热点主要涉及“风险评估”“风险分析”和“动物疫病防控”等方面。提示研究机构应加大动物疫病风险评估研究力度，加强各大研究机构间的合作，推进动物疫病风险评估的研究、分析、监管，完善预警机制，进一步提升我国动物疫病防控水平。本研究可为深化动物疫病风险评估研究、实践和预警提供参考。

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.
