基于知识图谱的碎石土堆积体滑坡研究热点及发展趋势
Research Hotspot and Development Trend of Gravel Soil Accumulation Landslide Based on Knowledge Graph

碎石土堆积体在我国发展起步较晚，在2008年汶川地震之后才逐渐进入科研学者的视野，并且在汶川地震后爆发式发展。为了探究我国学者在碎石土堆积体及其灾变方面的研究热点及其未来研究的发展趋势，本文以中国知网(CNKI)数据库中收录的与碎石土堆积体相关的223篇文章为基础，利用CiteSpace对碎石土堆积体的发文作者、机构、关键词热度、研究发展进程进行可视化分析并结合Bicomb得出的关键词共现矩阵分析领域研究的热点和预测未来的发展方向。分析表明：1) 发文作者和机构非常分散，且发文作者形成多个圈子，形成鼎立的状态，机构发文量集中在我国西南和湖南地区。2) 研究热点集中于数值模拟、滑坡、堆积体、稳定性、成因机制这五个方面。3) 碎石土堆积体的研究大概经历了三个阶段：萌芽期(2001~2006)、爆发期(2007~2016)、稳定期(2017~2021)。
Gravel soil accumulation started late in China. It gradually entered the vision of scientific researchers after the Wenchuan earthquake in 2008, and developed explosively after the Wenchuan earthquake. In order to explore the research hotspots and future research trends of Chinese scholars in gravel soil accumulation and its disasters, based on 223 articles related to gravel soil accumulation collected in CNKI database, this paper uses CiteSpace to publish the author, organization and keyword heat. The research and development process is visually analyzed, combined with the keyword co-occurrence matrix obtained by BICOMB to analyze the research hotspots in the field and predict the future development direction. The analysis shows that: 1) The authors and institutions are very scattered, and the authors form multiple circles and form a state of confrontation. The amount of institutional documents is concentrated in Southwest China and Hunan; 2) Research focuses on numerical simulation, landslide, accumulation, stability and genetic mechanism; 3) The study of gravelly soil accumulation has probably gone through three stages: germination period (2001~2006), outbreak period (2007~2016) and stability period (2017~2021).
