Progress of Mine Land Reclamation and Ecological Restoration Research Based on Bibliometric Analysis

The mining of mineral resources has caused serious damage to land and significant pressure on ecological environment. During the repairing damaged degraded ecosystems, there have been many pieces literature related reclamation restoration (LRER) that emerged. To understand progress prospect LRER research, it is necessary sort out such literature, analyze current research status, forecast future directions. Here, Bibliometrix R-package was used 2357 articles, which were derived from core database Web Science, explore development 1990 2022. results are as follows. (1) annual scientific output show both number articles published annually citied increasing gradually (2) High-frequency keyword analysis indicates heavy metal (Cd, Pb) pollution remediation a hotspot. cluster (CA) multiple correspondence (MCA) two clusters in LRER, one surrounds other focuses areas. correspond (rehabilitation) stages stepwise restoration, respectively. Thematic evolution shows that, for more than 30 years, mine drainage treatment, soil reconstruction (soil profile reconstruction, improvement), vegetation focus research. (3) Future should relationship between carbon sequestration biodiversity In addition, technology exchange, international cooperation, industrialization also main directions development. Generally, this study, metrology software (Bibliometrix 3.1.4) relevant over past years so provide reference LRER.
