生物土壤结皮(biological soil crusts,BSCs)具有独特的生理特征和多种生态功能,对维持生态系统稳定性有着重要作用.利用CiteSpace和VOSviewer,分析CNKI和Web of Science数据库中有关BSCs研究文献关键词、载文期刊、核心作者及机构,梳理不同时期研究热点.结果表明:1)"BSCs组成及多样性""BSCs对环境胁迫的生理生态响应""BSCs与土壤水文过程""BSCs水土保持效应"和"BSCs人工培育及其生态恢复实践"是不同时期的热点;2)聚焦BSCs对不同气候区环境胁迫的响应及机制,研究区域逐步由我国干旱及半干旱沙漠沙地区向高寒荒漠区、半干旱、半湿润区、湿润区和石漠化区拓展,研究视野从局地向区域和全球尺度转变;3)2002年后BSCs论文快速增长,我国作者的研究成果主要发表在《中国沙漠》《生态学报》《Catena》和《Geoderma》等期刊.未来的研究可能会趋于以下方面:1)多学科融合,打破学科壁垒统筹发展;2)科研过程与现代技术有更紧密的融合;3)以实际应用为落脚点,对人工培育BSCs在水土保持及生态修复的实践中应用有更深的研究与剖析.
Review on research progress of biological soil crusts in China based on bibliometrics
[Background]Biological soil crusts(BSCs)which has unique physiological characteristics and various ecological functions,play an important role in maintaining the stability of the ecosystem.With the deepening of desertification in China,the process of ecological restoration research should be gradually accelerated.Biological soil crusts are the pioneer group of ecological restoration under many extreme environmental conditions,and it is particularly important to grasp the research process,current hot spots and future directions of biological soil crusts[Methods]In this paper,the research hotspots in different period were determined by analyzing key words,journals,core authors and institutions of BSCs research literature in CNKI and Web of Science databases using CiteSpace and VOSviewer.In CNKI,searching pattern was SU='biological crusts'or SU='crusts'or SU='biological soil crusts'or SU='algal crusts'or SU='moss crusts'or SU='lichen'or SU='mixed algal-moss crusts'.In Web of Science,searching pattern was TS='biological soil crusts'OR'biological crusts'OR'biocrusts'OR'moss biocrusts'OR'cyanobacterial biocrusts'OR'lichen biocrusts'.Then we screened the search results one by one to select the sample literatures suitable for the research topic by removing conferences,announcements,news,and literature that are not relevant to the research topic.[Results]1)"Composition and diversity of biological soil crusts""Ecophysiological response of biological soil crusts to environmental stress""Biological soil crusts and soil hydrological processes""Soil and water conservation effects of biological soil crusts""Artificial cultivation of biological soil crusts and ecological restoration practice"were hot spots in different period.2)Focusing on the response and mechanism of BSCs to environmental stress in different climate regions,the research area gradually expanded from arid and semi-arid desert sand areas to alpine desert areas,semi-arid,semi-humid areas,humid areas and rocky desertification areas,and the research scale had changed from local to regional and global scales.3)The number of published papers increased rapidly since 2002.the research results of authors were mainly published in Chinese journals such as Journal of Desert Research,Acta Ecologica Sinica,and Journal of Soil and Water Conservation,and in English journals such as Catena,Geoderma,Soil Biology and Biochemistry,and Plant and Soil and Science of the Total Environment.[Conclusions]Future research may focus on the following aspects:1)The research on biological soil crusts will be cross-integrated with other disciplines,such as molecular biology,to break down disciplinary barriers and develop in a coordinated way.2)The process of scientific research is more closely integrated with modern technologies,such as information technology,medical technology,biotechnology,etc.3)The scientific research goal will be based on practical application,and will have a deeper research and analysis on the application of artificially cultivated BSCs in soil and water conservation and ecological restoration.
