Research on hotspots and trends of tectonic geomorphology in China： A perspective of Chinese bibliometrics analysis

As a new discipline in the field of earth science, tectonic geomorphology has unique significance and scientific connotation of resources and environment. Means of Chinese bibliometrics are used to analyze the academic papers in the field of tectonic geomorphology collected in CNKI from 1956 to 2019, especially the results reported in the last decade. Thereafter, the related research hotspots and trends are discussed. The key words and co-word analysis results show that: the remarkable characteristics of tectonic geomorphology are most closely correlated with tectonic units and seismic activities in China; further structural geology, geomorphology, geophysics and geographic information science play a crucial role in the progress of tectonic geomorphology. The research hotspots are constantly updated, palaeogeographic characteristics of energy basins, coupling effect of multiple influencing factors and response of sedimentary process are prominent research highlights. Lastly, the main research trends and directions of tectonic geomorphology in China are analyzed, and some opinions are put forward briefly.
