蜥蜴与气候变化的研究热点演变分析——基于Web of Science数据库

Analysis of the Evolution of Research Hotspots on Lizards and Climate Change:Based on the Web of Science Database

以Web of Science为数据源,应用文献统计分析软件CiteSpace绘制蜥蜴与气候变化研究领域的知识图谱,对该领域的年度发文统计、主要研究力量、合作关系、学科、期刊、研究前沿与知识基础、研究热点与发展趋势进行系统分析。结果表明:1)蜥蜴与气候变化研究领域的发文量不断增加,发展速度迅猛。2)发达国家是蜥蜴与气候变化领域的主要研究力量,美国与澳大利亚发文量最高,占据主要地位;澳大利亚詹姆斯库克大学是主要研究机构;同时,各个国家、机构间的合作不断增强。3)蜥蜴与气候变化研究领域文献涉及多个学科,已有的学科主要涉及生命科学领域。4)当前该领域的7个研究热点分别为体温调节、系统发育与物种进化、生物多样性、脆弱性、评估与模型、保护管理以及气候变化;其中体温调节、系统发育、物种进化与脆弱性方面依旧是国际上该领域的研究热点。

Taking the Web of Science as the data source,CiteSpace(5.7.R5W)a literature statistical analysis software was used to draw the knowledge map of the lizard and climate change research field,the annual statistics of the field,the main research strength,cooperation relations,disciplines,journals,Systematic analysis of research preface and knowledge base,research hotspots and development trends.The results show that:1)The number of papers published in the field of lizards and climate change is increasing,and the development speed is rapid;2)Developed countries are the main research force in the field of lizards and climate change,and the United States and Australia have the highest number of papers,occupying a major position;Australia’s James Cook University is the main research institution;moreover,the cooperation between various countries and institutions is constantly increasing;3)The literature in the field of lizard and climate change research involves multiple disciplines,and the existing disciplines mainly involve the field of life sciences;4)The current seven research hotspots in this field are thermoregulation,phylogeny and species evolution,biodiversity,vulnerability,assessment and modeling,conservation management,and climate change.Among them,thermoregulation,phylogeny,species evolution and vulnerability are still the research hotspots in this field in the world.
