[Natural science research in Changbai Mountain during 1956-2018:A review.]

We synthesized the scientific research carried out in Changbai Mountain from 1956 to 2018 by mapping knowledge domains and bibliometrics based on the literature from international database (WOS) and domestic databases (CNKI and CSCD). The results showed that natural science research in Changbai Mountain underwent three stages during 1956-2018, including embryo stage, growing stage, and rapid development stage. The natural research in Changbai Mountain could be divided into five fields, i.e., forest and ecological science, volcano and geology science, environmental change science, resource sciences and utilization, animal and microbial science, with a total of 20 main research directions. Since 2000, forest and ecological science, volcano and geological science, environmental change science dominated the natural science research in Changbai Mountain. The researches in recent 20 years mainly concentrated on the following seven disciplines: community ecology, forest management, soil ecology, ecosystem ecology, eco-climatology, forest responses to environmental change, and volcanic geology. International researches showed a trend of strong integration of different disciplines. We forecast that the natural science research in the Changbai Mountain would deepen its research in the next decade. Moreover, other fields such as old-growth forest and large-scale ecosystem carbon processes, forest-altitude-climate change, soil fauna and microorganisms, forest management and human activities, biodiversity, volcanic origin and eruption history, volcanic eruption dynamics and volcanic monitoring will emerge as the new research focus. Scale polarization, elements diversification, discipline crossing, and research deepening would be the future trend of natural science research in Changbai Mountain.以国际(WOS)、国内(CNKI、CSCD)数据库中收录的长白山自然科学研究文献为基础,利用知识图谱与文献计量学方法对长白山地区1956—2018年开展的科学研究进行综述.结果表明: 1956—2018年,长白山地区自然科学研究经历了萌芽期、成长期和快速发展时期,形成了以森林与生态科学、火山与地质科学、环境变化科学、资源科学及开发利用、动物与微生物科学为主的五大研究领域,共20个主要研究方向.2000年以来,森林与生态科学、火山与地质科学和环境变化科学成为长白山地区的研究热点,主要集中在群落生态学、森林经营学、土壤生态学、生态系统生态学、生态气候学、森林响应环境变化、火山地质学7条主线上,国际研究更呈现学科交叉融合的态势.未来10年,国内与国际长白山科学研究除在原有热点领域上不断深耕外,老龄林及大尺度生态系统碳过程、森林-海拔-气候变化、土壤动物与微生物、森林经营与人类活动、生物多样性、火山起源与喷发历史、火山喷发动力学与火山监测等方面将是研究重点.学科交叉化、尺度两极化、内容深入化、要素多样化将是未来研究的发展趋势.
