摘要借助CiteSpace和HistCite文献计量方法，以CNKI和Web of Science核心合集中的生物土壤结皮领域研究文献为对象，通过对文章数量、主题词及团队的分析，梳理国内外生物土壤结皮研究总体态势。研究结果有：1）生物土壤结皮研究领域发表的论文总体呈上升趋势，美国和中国发文量名列前2位，国内排前2位的依次是中国科学院寒区旱区环境与工程研究所和中国科学院新疆生态与地理研究所。2）与其他国家相比，我国生物土壤结皮研究虽然起步较晚，但2000年后文献呈激增趋势，2011年后国际热点区域主要集中在我国；生物结皮组成、演替、季节变化及对碳氮循环、土壤理化性质、土壤水分和土壤侵蚀的影响，以及对干扰的响应是研究热点和重点。3）国内生物土壤结皮研究形成了以中国科学院寒区旱区环境与工程研究所李新荣为核心的团队，中国科学院新疆生态与地理研究所的张元明研究团队、西北农林科技大学的赵允格团队和卜崇峰研究团队、中国科学院水生生物研究所形成了以刘永定为核心的研究团队等，且李新荣、张元明和赵允格3大团队之间有较强的合作关系。
Abstract：[Background] Biological soil crust (BSC) is an integral part of ecosystems, playing an important role in soil hydrology, nutrients cycling and stabilizing soils. Summarizing the research trends of BSC in China and abroad would provide reference basis for relevant research.[Methods] CiteSpace and HistCite were employed to explore the number, keywords and research team based on the literatures selected from CNKI and Web of Science core database. In Web of Science,searching pattern was TS=(biological crusts or biological soil crusts or biocrust or moss soil crusts or lichen soil crusts or cyanobacterial soil crusts or algal soil crusts) not TS=(sea or marine or ocean or reservoir or lake or physical soil crusts or salt crusts or bread or aquatic or drug or crystalline lattice) and TS=soil. In CNKI, searching pattern was SU=‘biological crusts’ or SU=‘crust*’ or SU=‘biological soil crusts’ or SU=‘algal crust’ or SU=‘moss crust’ or SU=‘lichen’ or SU=‘mixed algal-moss crust’.[Results] 1) The number of published articles in the field of BSC appeared an overall upward trend. More specifically, USA and China were the top two countries contributing to these articles, while Cold and Arid Regions Environmental and Engineering Research Institute and Xinjiang Institute of Ecology and Geography of Chinese Academy of Sciences were the top two institutions in China. 2) Compared with other countries, China's BSC research started relatively late, but the numbers of articles increased sharply since 2000; further, some research area in China have been hot regions of international BSC research. The composition, succession and seasonal change of BSC and their effects on carbon and nitrogen cycling, soil physical and chemical properties, soil hydrological process and soil erosion, as well as responses of BSC to disturbance were research hotspots. 3) It has formed some core academic teams with LI Xinrong in the Cold and Arid Regions Environmental and Engineering Research Institute of CAS, ZHANG Yuanming in the Xinjiang Institute of Ecology and Geography of CAS, ZHAO Yunge in the Northwest A&F University and BU Chongfeng in the Northwest A&F University, and LIU Yongding in the Institute of Hydrobiology, CAS. Moreover, there was a strong cooperative relationship among three teams of LI Xinrong, ZHANG Yuanming and ZHAO Yunge.[Conclusions] Through summarizing and analyzing research focus issues and research hotspot BSC, it is conducive to researchers to comprehensively understand research history and present situation of BSC at home and abroad.
