基于知识图谱的土壤重金属快速监测技术进展

A review of the rapid monitoring of soil heavy metals based on mapping knowledge domains

为了解当前国际土壤重金属快速监测研究现状及趋势,以Web of science数据库为基础,以X射线荧光光谱法(XRF)为例利用Cite Space进行知识图谱可视化分析,并在此基础上对国际土壤重金属快速监测进行研究综述.结果表明,从Web of science数据库资料来看,当前对土壤重金属快速监测的研究机构以中国科学院和西班牙国家科学研究委员会发文量最多,而发文从属国家以美国为最多,中国和德国居其次;研究热点主要集中于快速监测仪器的技术开发、实际应用、定量化监测影响因素的识别及校正等方面;针对土壤重金属污染快速监测的未来研究趋势主要集中于监测仪器的小型化智能化研发、农田土壤重金属快速监测、区域土壤重金属空间分布监测等方面.认清和了解当前国际土壤重金属快速监测研究状况,可为国内相关研究提供参考.

Soil heavy metal pollution has been paid increasing attention. A method that rapid detection of soil heavy metal concentrations was provided for the field screening and monitoring of soil heavy metal pollution. Aiming to understand the research status and trend of soil heavy metal rapid monitoring, X-ray fluorescence （XRF） was used as an example for visualized analysis by software CiteSpace based on the Web of Science database. The results showed that： （1） As the term of Agent, the largest amount of literature around rapid monitoring of heavy metals were reporteded by the Chinese Academy of Sciences and the National Scientific Research Council of Spain. As the term of country, the reports were dominated by the United States, followed by China and Germany. （2） The instrument development, practical application and the factors influencing quantitative monitoring were the research concern. （3） The future research possibly focused on the instrument miniaturization and intelligence, rapid monitoring of farmland soil heavy metal and the monitoring of spatial distribution of soil heavy metal. The review on soil heavy metal rapid monitoring could provide reference for related research in China.
