中国沙障研究进展与热点分析：基于Vosviewer和Citespace的图谱量化分析

基于Vosviewer和Citespace的图谱量化分析，选取1980—2020年以中国知网（CNKI）、万方数据、维普资讯为数据源的1 462篇关于中国沙障研究的文献，以及2000年后发表在外文期刊上的关于沙障的高被引文章50篇为样本，统计并绘制文献产出量变化、关键词共现、作者合作共现、机构合作以及突变和时区变化图谱等，厘清中国沙障研究的现状及挖掘热点问题。结果表明：中国沙障研究文献产出量可分为4个阶段：1980—1990年处于起步阶段、1990—2000年处于发展阶段、2000—2010年处于迅猛发展趋势、2010—2020年处于高平稳发展趋势；关键词共现主要在沙漠治理、植物固沙、乌兰布和沙漠和库布齐沙漠、风洞和数值模拟、沙障自动铺设机；作者和机构之间的合作表现为整体分散、部分集中的形式，缺乏成员、组织之间的相互交流和合作；突变分析表明，2013年后，中国沙障的研究热点为水土保持、植被恢复、数值模拟、风速流场、输沙量、防沙治沙措施以及防沙治沙政策的制定，以上热点也必将是未来一段时间的热点问题。展望未来，尽管中国荒漠化总体趋势有所遏制，但荒漠化治理依然任重道远。

Research progress and hotspot analysis of sand barrier in China Quantitative analysis of atlas based on Vosviewer and Citespace

Based on the quantitative analysis of the atlas of Vosviewer and Citespace,1 462 literatures on the study of sand barriers in China from 1980 to 2020 using CNKI,Wanfang data and Weipu information as data sources were selected as samples,and 50 highly cited articles on sand barriers published in foreign journals after2000 were selected as samples. Statistics and mapping of literature output change,keyword co-occurrence,cooccurrence of authors’ cooperation,institutional cooperation,mutation and time zone change were conducted to clarify the current situation of sand barrier research in China and explore hot issues. The results show that:the output of sand barrier research literature in China can be divided into four stages:1980-1990 in the initial stage,1990-2000 in the development stage,2000-2010 in the rapid development trend,2010-2020 in the high and stable development trend;the key words are mainly desert control,plant sand fixation,Ulan Buhe desert and Kubuqi Desert,wind tunnel and numerical simulation,automatic sand barrier The cooperation between the author and the organization is in the form of "overall dispersion,part concentration",lacking of mutual communication and cooperation between members and organizations;the analysis of abrupt change time zone shows that after 2013,the research focus of sand barrier in China is soil and water conservation,vegetation restoration,numerical simulation,wind speed and flow field,sediment transport,sand control measures and formulation of sand control and prevention policies,These hot spots will also be hot issues in the future. Looking forward to the future,although the overall trend of desertification in China has been curbed,there is still a long way to go for desertification control.
