基于文献计量学的“十三五”生态环境监测研究热点分析

利用科学计量与可视化相关工具,以《中文核心期刊要目总览(2017年版)》27种环境科学类核心期刊发表的2016—2020年生态环境监测论文数据为基础,从载文量分布、高被引论文、高产机构分布和技术主题分布等方面分析了"十三五"期间我国生态环境监测研究热点。结果表明:"十三五"期间生态环境监测论文数量有所增加,主要载文期刊分布于《环境科学》《中国环境监测》《环境科学与技术》;主要发文机构是中国环境科学研究院、中国环境监测总站、中国科学院大学;排名前10位的技术主题词分别是PM_(2.5)、重金属、土壤、污染特征、颗粒物、挥发性有机物、生态风险、臭氧、沉积物、多环芳烃,结合"十三五"前期和中后期热点主题词变化分析了生态环境监测研究关注点的变化趋势。

Analysis of Research Hotspots of Ecological Environment Monitoring in the 13th Five-Year Plan Based on Bibliometrics

Based on the data of CNKI journals, this paper analyzed the research hotspots in the field of ecological environment monitoring in China during the 13th Five-Year Plan period from the distribution of core journals, highly cited papers, high-yield institutions, high-yield authors, author cooperation network and technical topics by using the tools of scientometrics and visualization. The results showed that the number of papers on eco-environmental monitoring had increased in the study period, and the main journals were distributed in Environmental Science, China Environmental Monitoring, and Environmental Science and Technology. The main publishing institutions were Chinese Academy of Environmental Sciences, China Environmental Monitoring Station, University of Chinese Academy of Sciences, National Marine Environmental Monitoring Center, School of Environmental Science and Engineering of Nanjing University of Information Technology, College of Environmental Science and Engineering of Nankai University. The top 10 technical keywords were PM_2.5, heavy metals, soil, pollution characteristics, particulate matter, volatile organic compounds, ecological risk, ozone, sediment and polycyclic aromatic hydrocarbons. Combining with the changes of hot topics in the early and mid-late 13th Five-Year Plan period, the trend of the focus of ecological environment monitoring research was analyzed.
