The evolution and frontier development of land ecological restoration research

Ecological restoration of the land is a major measure to promote ecological protection and restoration, serve the construction of ecological civilization and accelerate the development of modernization. It is of great significance to human survival and social progress. This paper uses the bibliometrics and network analysis methods, takes 1196 articles in the Web of Science database as the research object, deeply analyzes the dynamic trends, cooperation and research hotspots of the land ecological restoration research, further discriminates the evolution process and explores the progress of the frontier. The research shows that: (1) The land ecological restoration has been increasingly concerned by academic circles at home and abroad, and the research literature mainly concentrates on the fields of ecology and environment. (2) Scholars and research institutions in developed countries such as the United States have prominent influence in this field. China has shown strong development potential and is a core member of the emerging cooperative group, and the Chinese Academy of Sciences has become one of the most influential institutions in the world. (3) The elements of water, soil and population with ecology as the core are the main research objects in this field, and the comprehensive research under the intersection of humanities and natural sciences is the future development trend of this field.
