中国极端气候事件研究态势文献计量学综述

Bibliometric review on status of extreme climate events in China

目前极端气候事件已经严重威胁了中国的生态平衡与安全.从Web of Science(WOS)和中国知网(CNKI)数据库核心合集筛选2000-2021年间研究中国境内极端气候事件对生态系统影响的相关文献信息,并作为数据源,基于CiteSpace软件进行统计分析.结果表明:(1)该领域中英文文献逐年发文量在整体上均呈上升趋势,其中英文文献的增长速度尤为明显;(2)中国是发文量最高的国家,中国科学院在该领域有着较强的影响力,Zuo Xiaoan和温震军等作者对该领域具有较大贡献;(3)研究区域以内蒙古和中国西北地区为主,研究的主要生态系统类型为草地生态系统,研究方式以数据统计、模型分析为主,研究生物视角为植被生长和植被绿度,研究的主要极端气候类型为极端干旱和极端降水,研究前沿热点为极端干旱.

At present,extreme weather events have seriously threatened China’s ecological balance and security.Based on the core collection of Web of Science(WOS)and China National Knowledge Infrastructuret(CNKI),this paper selects the literature information related to the impact of extreme climate events on ecosystems in China from 2000 to 2021 as the data source,and makes statistical analysisbased on CiteSpace software.The results show that:(1)The number of Chinese and English documents published in this field shows an upward trend year by year,especially the growth rate of English documents;(2)China is the country with the highest number of publications,and the Chinese Academy of Sciences has a strong influence in this field.Authors such as Zuo Xiaoan and Wen Zhenjun have made great contributions to this field;(3)The research area is mainly in Inner Mongolia and Northwest China.The main ecosystem type studied is grassland ecosystem.The research method is mainly based on data statistics and model analysis.The biological perspective is vegetation growth and vegetation greenness.The main extreme climate types studied are extreme drought and extreme precipitation.The research frontier hot spot is extreme drought.
