国内土壤重金属风险评价热点主题和前沿演进

Hot topics and frontier evolution on soil heavy metals risk assessment in China

为揭示我国土壤重金属风险评价领域研究现状及前沿热点,笔者基于2001—2021年中国知网(CNKI)数据源,利用CiteSpace软件对国内该领域1485篇期刊论文进行文献计量学分析,多维度挖掘土壤重金属风险评价研究的形势以及未来重点研究方向。结果显示:该研究领域科研论文发文量总体呈增长趋势,研究热点主要围绕污染评价、生态风险评价和健康风险评价等3个方面;何腾兵、麦麦提吐尔逊·艾则孜、艾尔瓦尔·买买提、阿吉古丽·马木提、马建华是该研究领域不同时期的重要研究学者;陕西师范大学、新疆师范大学、中国科学院大学是该领域具有较强学术影响力的研究机构。在生态文明建设的迫切需求下,未来该领域的研究热点可能集中在耕地土壤、风险评估等方面。

In order to reveal the research status and hotspots in the field of soil heavy metals risk assessment in China,based on the data source of China National Knowledge Infrastructure from 2001 to 2021,CiteSpace software was used to conduct bibliometric analysis of 1485 journal papers in this field in China,the overall situation and the key research direction in the future of soil heavy metals risk assessment is explored in multiple dimensions.The results showed that the number of scientific research papers published in the field of soil heavy metal risk assessment shows an increasing trend,the research focus mainly surrounding three aspects:pollution,ecological risk assessment and health risk assessment.He Tengbing,EZIZ Mamattursun,MOHAMMAD Anwar,MAMUT Ajigul and Ma Jianhua are important research scholars in different periods in this research field,Shaanxi Normal University,Xinjiang Normal University and the University of Chinese Academy of Sciences are the important research institutions with strong academic influence in this field.Under the urgent need of ecological civilization construction,the research hotspots in this field may focus on the cultivated land soil and risk assessment in the future.
