为了解我国危化品安全生产科技研究现状,揭示危化品安全生产科技的动态演化过程,以中国知网文献数据为来源,采用文献计量法对2006—2014年的危化品安全生产科技相关文献进行挖掘、整理、分析。通过对比2006—2011与2012—2014年2个时间段关键词词频排序,共词聚类2012—2014年的高频关键词,分析我国危化品安全生产科技的主题结构及研究热点变化情况。研究表明:危化品、天然气管道、化工园区等关键词相关的安全生产科技,其关注度依旧较高,但针对这些传统领域的科技研发呈现出新的特点,围绕动态分级、生命周期、云计算等关键词开展的科技研究逐渐成为关注热点和优势方向;2012—2014年我国危化品安全生产科技可以归纳为6个主要研究领域。
In order to understand the status quo of research on safe production technology of hazardous chemicals in our country and to reveal the dynamic evolvement process of safe production technology of hazardous chemicals, taking the data of CNKI as the source, using the bibliometric method to analyze the safety of hazardous chemicals in 2006-2014 Document mining, sorting, analysis. By comparing the keyword frequency rankings of two periods of 2006-2011 and 2012-2014 with those of 2012-2014, the key words of 2012-2014 are co-clustered to analyze the theme structure and research hotspot of safe production technology in our country. The research shows that the safety science and technology related to key words such as hazardous chemicals, natural gas pipelines and chemical parks are still paying more attention. However, the research and development of science and technology aimed at these traditional areas show new characteristics. Based on the dynamic classification, life cycle, Calculation and other key scientific and technological research carried out gradually become the focus of attention and advantages direction; 2012-2014 China’s hazardous chemicals safety production technology can be grouped into six major areas of research.
