英文摘要	Rare earth (RE) mining activities have caused the vegetation destruction, soil erosion, soil desertification and other ecological problems. To quantitatively evaluate the eco-security of the RE mining area, we took Lingbei RE mining area in Dingnan County as study area and used the PSR (Pressure-State-Response) model and AHP (Analytic Hierarchy Process) method to construct its eco-security assessment system which was made up of 3 criterion levels and 10 factors. The results showed that the forest land had the most contribution to the eco-security in the RE mining area, and the tailings produced by RE mining had less; the average value of the eco-security in the mining area increased from 6.99 in 2008 to 7.00 in 2014. The natural growth and reclamation of the vegetation in the mining area could improve the eco-security. Vegetation destruction and exploiting RE would worsen it; mining RE would directly lead to the deterioration of the eco-security.
