基于CiteSpace的草地鼠害研究现状及热点分析

草地鼠害严重威胁草地生态安全。中国在草地鼠害研究领域做了大量的工作，发表了大量学术论文。本研究通过文献计量方法，统计了1977—2021年中国草地鼠害研究领域Web of Science (WOS)和中国知网(China National Knowledge Infrastructure，CNKI)数据库收录论文的数量、被引情况、H指数等指标，同时利用CiteSpace对论文的研究力量和研究热点等进行分析。结果表明：1977—2021年，中国草地鼠害研究领域共发表1 140篇文章，其中CNKI发文584篇，WOS发文556篇，且整体上逐年增加；中国科学院和兰州大学在草地鼠害研究中处主导地位，但不同的研究机构、不同的作者之间联系不够紧密；研究对象集中于高原鼠兔(Ochotona curzoniae)和高原鼢鼠(Myospalax baileyi)，研究地点集中于青藏高原和高寒草甸，研究方向以种群密度、多样性和土壤有机碳为主。

Current Research Status and Hot Spots of Grassland Rodent Pests Based on CiteSpace

Grassland rodent pests seriously threaten the healthy and sustainable development of grassland in China,therefore,China had done a lot of work with grassland rodent research,and published many papers. This study used bibliometrics to count the numbers and citations of the grassland rodent pests papers included in the WOS (Web of Science) and CNKI (China National Knowledge Infrastructure) databases from 1977 to 2021,and this study also used the CiteSpace software to analyze the research strength and research hotspots of these papers. This study showed that there were 1 140 papers about grassland rodent pests during the period 1997—2021,in which CNKI had published 584 papers and WOS had published 556 papers,in addition,this study showed that the number of the papers increased year by year. The results of the research hotspot showed that the main research forces were the Chinese Academy of Sciences and Lanzhou University,and there was no close connection between different research institutions and different authors in the research forces. Meanwhile,the results of the research hotspot also showed that the main research object was plateau pikas and plateau zokors,the main research location was Qinghai-Tibet Plateau and alpine meadows,and the main research content related to population density,diversity,and soil organic carbon.
