东北黑土区沟蚀研究进展与热点 ———基于CiteSpace计量分析.

[Objective]. The aims of this article are to intuitively grasp the progress and hotspots in the field of research of gully erosion in the northeast of China black soil region, advance the development of research in gully erosion in the black soil region of northeast China. [Methods] 245 papers in CNKI and Web of Science databases were used to create a knowledge map of gully erosion in the black soil region of northeast using the bibliometric method and CiteSpace software. [Results] (1) Research on gully erosion in black soil area started late, and the number of published papers has increased significantly in the past 10 years, but the results published in international journals are few, accounting for only 26%. (2) The research institutions in this field mainly distribute in northeastern China, of which several institutions include Songliao Basin Committee of Ministry of Water Resources, Beijing Normal University, Northeast Institute of Geography and Agroecology of Chinese Academy of Sciences, Northeast Agricultural University, and Shenyang Agricultural University have made the outstanding contributions and shown the great influence in the field; Prof. Zhang Shuwen is the scholar with the most publications in Chinese, and Prof. Liu Baoyuan and Wu Yongqiu are the scholars with the most publications in English in this field. (3) The co-occurrence of keywords between the published literatures indicates that the current focus of attention on gully erosion in the black soil area of northeast China is mainly on the development characteristics, influencing factors and prevention and control measures of gully erosion. [Conclusion] The comprehensive research framework and a full understanding on gully erosion in the black soil region of northeastern China have not yet been established. In future research, there is a need to further emphasize the study of the formation and development processes and mechanisms of gully erosion in the black soil region of Northeastern China, and to conduct in-depth analyses of the influences of geological, topographical, hydrological, and human activities, among other factors.
