Research hotspots and trends in vegetation reconstruction in Chinese mines:A bibliometric analysis based on CiteSpace
Mine vegetation reconstruction is the basic form and key process of mine ecological restoration,which is an important measure for the ecological civilization construction in China.By clarifying the historical development,disciplines,research hotspots,and phased a-chievements of mining vegetation reconstruction research in China over the past 30 years,as well as predicting future development trends,CiteSpace software was used to quantitatively analyze the relevant literature published on CNKI from 1994 to 2023.The historical develop-ment of mine revegetation in China has gone through three stages,start-up period,rapid breakthrough period and stable developing period,with an upward trend.Environmental science,mining science and biology were the main related disciplines of mine vegetation reconstruc-tion.Based on the keyword co-occurrence mapping by CiteSpace,we found that land reclamation,ecological restoration and ecological vege-tation reconstruction were the three major hotspots in this field.The keyword emergent analysis also revealed that the hotspots of mine veg-etation reconstruction had evolved from early land reclamation and mine regreen to modern multifunctional vegetation involving ecological and landscape values.Mine vegetation reconstruction technology combining remote sensing,artificial intelligence,robotics technology,and the theoretical framework of landscape ecology and sustainability science will be the future direction in this field.
