水土保持研究

耕作侵蚀是新兴的土壤侵蚀研究领域。以“tillage erosion”为关键词在Web of Science核心数据库检索1990—2020年相关文献,通过CiteSpace方法开展耕作侵蚀研究的国家、作者、学科、期刊共现网络分析、引文共被引分析和关键词共现分析。结果显示:1990—2020年耕作侵蚀研究的文献量逐年增加,处于快速增长阶段; 比利时的相关成果被引频次最高(58次),德国的中介中心性最高(0.50),中国具有最高爆发值(6.91),显示出中国的耕作侵蚀研究起步相对较晚但处于现阶段该研究的前沿; 以Govers,Poesen,Lobb,Zhang,Qunie等为核心的科研团队对耕作侵蚀学科发展的贡献尤其显著,Lobb团队研究具有最高的中介中心性,被其他研究者广泛引用,张建辉团队研究具有最高的爆发值,受关注度高; 关键词共现分析显示耕作侵蚀与粮食安全、耕作侵蚀与土地利用、耕作侵蚀对土壤景观变异性和水文过程变化的影响是现阶段研究的重要方向。随着更多国家和学者对耕作侵蚀研究的重视,耕作侵蚀学科的发展将在未来水土保持科学与技术中发挥重要作用。

Tillage erosion is a new research field of soil erosion. In the present work,tillage erosion was used as the key word to search relevant literatures from 1990 to 2020 in the Core Database of Web of Science,and the co-occurrence network analysis of countries,authors,disciplines and journals,the cited reference analysis and keywords co-words analysis in the field of tillage erosion were conducted by CiteSpace. The results indicate that the amount of literature on tillage erosion from 1990 to 2020 had been increasing rapidly year by year,showing a trend of rapid development. Belgium has the highest frequency of citations(58 times),Germany has the highest centrality(0.50),and China has the highest burstiness value(6.91),indicating that the tillage erosion research in China started relatively late but is at the forefront of this research field. The scientific research teams including but not limited to Govers,Poesen,Lobb,Zhang,Qunie have made significant contributions to the development of the discipline of tillage erosion. For instance,the team of Lobb has the highest centrality and their findings were widely cited by other researchers. And Zhang's team has the highest burstiness value and their findings have received high attention. The result of keyword co-word analysis shows that tillage erosion and food security,tillage erosion and land use,the impact of tillage erosion on soil landscape variability and the hydrological process are the main research domains of tillage erosion at present. The development of tillage erosion will play an important role in the science and technology of soil and water conservation in the future as scholars pay more attention to tillage erosion research.
