【摘要】：崩岗是一种发育在中国南方低山丘陵地区的水土流失地貌类型,侵蚀量巨大,危害严重。为回顾半个世纪以来中国崩岗研究的发展历程,以中国知网(CNKI)数据库为数据源,统计分析1966—2016年间以"崩岗"为主题的文献数量、时间分布及载文期刊情况,基于Cite Space对崩岗研究知识图谱进行可视化挖掘与分析,识别出核心作者群、主要研究机构及高频关键词。研究结果表明:1)半个世纪以来中国崩岗研究的论文数量整体呈现区间波动增长的态势。2)载文期刊以水土保持学科为主,学科交叉研究有待加强;期刊影响因子总体偏低,反映崩岗研究水平有待提高。3)研究机构之间学术交流较少,科研实力差异显著,有待加强交流合作,实现共同发展。4)中国崩岗研究主要围绕"崩岗""崩岗侵蚀""土壤侵蚀""水土流失""坡面""风化壳"等展开,"崩积体"和土体"抗剪强度"是近年来崩岗研究的热点。崩岗研究产出论文大部分与防控治理措施有关,定量研究较少。研究结果有助于科研工作者对中国崩岗研究历史与现状有较全面、客观、准确的认识,从而更好地精炼研究方向,为崩岗的后续研究提供更深入具体的指导。
[Abstract]:Avalanche is a geomorphologic type of soil and water loss developed in the low mountain and hilly area of southern China. The erosion amount is huge and the damage is serious. In order to review the development of the research on collapse of hillock in China in the past half century, using CNKI database as the data source, this paper analyzes the number, time distribution and the status of published journals of the literature on the subject of "collapse of the hill" in 1966-2016. Based on Cite Space, the authors' core authors, main research institutions and high frequency keywords are identified by visualizing and analyzing the knowledge map of collapse research. The results show that the number of papers published in China in the past half century shows an increasing trend of fluctuation. 2) the main subject of published journals is soil and water conservation, the interdisciplinary research needs to be strengthened, and the influencing factors of journals are on the low side. The result shows that the level of research on collapse of hillock needs to be improved. 3) there is less academic exchange among research institutions, there are significant differences in scientific research strength, and communication and cooperation need to be strengthened. To achieve common development. 4) the research of rockfall in China is mainly focused on "collapse", "collapse erosion", "soil erosion", "slope erosion", "weathering crust" and so on, and "avalanche body" and "shear strength" of soil are the hot spots in recent years. Most of the papers are related to the measures of prevention and control, but the quantitative research is less. The research results are helpful for the researchers to have a more comprehensive, objective and accurate understanding of the history and present situation of the research on the collapse of the hillock in China, so as to better refine the research direction and provide more in-depth and concrete guidance for the follow-up study of the collapse of the hill.
