基于WoS平台的中外水土保持研究计量学比较分析

[目的]对比分析中外水土保持研究的文献增量趋势、学科分布、机构和作者的合作网络以及水土保持研究热点,为中国相关领域学者、科研机构以及政府管理部门在加强国际科研合作以及关注农业农学问题研究等方面提供科学有益的参考。[方法]以Web of Science(WoS)数据库1986—2015年中外水土保持文献数据为对象,以知识图谱的方式,运用CiteSpace计量学分析软件对引文数据进行了分析和处理。[结果]中外水土保持研究文献总量均呈稳定增长趋势;美国、中国、澳大利亚占据了文献产出国家排名的前3位,欧洲高产国家最多;总体学科领域跨度较大,新兴学科增长明显;中外机构合作联系紧密,树状图谱枝杈丰满,形成了以中国、美国为重要产出节点的合作生态链;比利时的佩森(Poesen J)、戈韦尔(Govers G)等学者产出最多,且在各国学者合作中起到了重要的桥接作用。[结论]中外在水土保持研究热点上十分接近,土壤侵蚀、径流和建模是中外频次最高的研究热点关键词。

A Literature Comparative Analysis on Soil and Water Conservation Between China and Foreign Countries Based on Web of Science

[Objective] This study intended to compare the literature incremental trend of international studies on soil and water conservation, discipline distributions, cooperation network of institutions and authors, and research hot spots between China and foreign countries. It aims to provide a scientific and practical implication for scholars in the related fields, research institutions and government departments to enhance the citation frequency, strengthen international cooperation and pay attention to the research of agricultural science and so on. [Methods] Based on literature from 1986 to 2015 from the Web of science databases, CiteSpace visualization analysis software was used to analyze and process the citation data in the way of mapping knowledge domains. [Results] The literature on soil and water conservation increased steadily. United States, China, and Australia were ranked as the top three countries in the document output. European countries were the most high-yielding. The literatures span more disciplines, new disciplines emerged significantly. The cooperation between China and foreign institutions was closer; The tree diagram showed that an important cooperation ecological chain was established by China and America as an important output node. The most productive researchers were Belgian Poesen and Govers etc. who played an important role in bridging the academic cooperation between China and foreign countries. [Conclusion] The international research focus was similar. The soil and water conservation, soil erosion, runoff and model were the highest frequency hot keywords.
