1986—2020年黄河流域冻土研究中文文献计量分析

Chinese bibliometric analysis on permafrost research in the Yellow River Basin from 1986 to 2020

通过以中国知网内“黄河&冻土”关键词检索到的文献作为数据支撑,结合文献本身信息,运用数学和统计学的研究方法,利用Python作为数据分析及可视化工具研究在黄河流域内关于冻土方面的研究现状及热点分析。研究表明:(1)1986—2001年期间,发文量维持在每年1~2篇,从2001年以后,发文量呈上升趋势,但整体依旧较少,且有较大波动。(2)国内对于黄河流域冻土的研究单位主要分布在黄河附近省份,且以中国科学院西北生态环境资源研究院和兰州大学等西北地区单位为主要研究力量。(3)研究内容主要以黄河源区内多年冻土气候变化、生态环境等为关键研究点,其中“黄河源区”“气候变化”“多年冻土”为高频关键词。

The research status and hotspots of permafrost in the Yellow River Basin were analyzed by using the literature retrieved from the keyword“Yellow River&Frozen Soil”in CNKI as data support,combined with the information of literature itself,using mathematical and statistical research methods and Python as the data analysis and visualization tool.The results show that:(1)During the period of 1986—2001,the number of articles published is maintained at 1 or 2 per year,and since 2001,the number of articles published shows an upward trend,but the overall number is still small and fluctuates greatly.(2)The domestic research units on permafrost in the Yellow River Basin are mainly distributed in provinces near the Yellow River,and with Northwest Institute of Ecological and Environmental Resources of the Chinese Academy of Sciences and Lanzhou University as the main contributors.(3)The research content mainly focuses on the impact of permafrost on climate and ecological environment in the source area of the Yellow River,among which“the source area of the Yellow River”“climate change”and“permafrost”are the high frequency keywords.
