基于CiteSpace知识图谱的国内土壤侵蚀研究热点及趋势

Hotspots and Prospects of Soil Erosion Research in China Based on CiteSpace Maps

土壤侵蚀是土地退化的重要原因,相关研究领域广、问题解决需求迫切。为更好地了解近年来土壤侵蚀研究发展动态,本文选取中国知网的中文核心期刊和CSSCI来源期刊,借助CiteSpace软件对近十年土壤侵蚀研究文献进行统计,绘制相应知识图谱,分析领域的学术网络、基础热点、阶段前沿,并进一步提出学科发展的趋势预测及所需应对的问题。结果表明:2008-2017年,国内土壤侵蚀研究已形成一定规模的合作网络;内容上以主要侵蚀区为重要载体,从坡面和流域两层次展开研究,主题紧密结合地理信息技术,侵蚀机理及模型建立、侵蚀治理与水土保持类成果较多;阶段性前沿出现了由表层景观、具体机理,到生态服务的转向;未来将在此基础上走向深入的科学定量与生态关怀。

As the main cause of land degradation,soil erosion has a wide field and is urgent to solve.In order to better grasp the developing trends of this subject in China,here analyzed Chinese core journals and CSSCI journals of CNKI in 2008-2017 with corresponding CiteSpace knowledge maps relating to the academic network,the basic fields and the stage frontier.Also,the predictions of trends and problems were further putting forward.Conclusions are as follows:from 2008 to 2017,a certain scale of cooperative network had formed;areas of severe erosion were taken as important sites,and the research was primarily carried out from two levels of slope and watershed;its contents were closely combined with geographic information technology,then achievements in erosion mechanism and model building,erosion control and soil and water conservation were showing up;there was a transition from surface landscape,concrete mechanism to ecological service.All these lend substance to the argument that scientific quantitative and ecological care may become the quite illustrations of its future.
