Mining plays an indispen sable role in the process of industrialization and urbanization in China,and due to over-exploitation,the problem of pollution by potentially toxic elements(PTEs)in mining areas has gradually come to the fore.PTEs in the mining process will not only damage the local ecological environment,but also cause large-scale pollution through rainfall,surface runoff and atmospheric precipitation,etc.Therefore,it is crucial to carry out the evaluation of pollution in the mining area and ecological management and restoration.This paper will summarize the pollution evaluation methods of PTEs in mining areas:Nemero pollution index,geological cumulative index,potential ecological hazard index;and ecological remediation techniques in mining areas:physical remediation,chemical remediation and bioremediation techniques,in order to provide guidance for better ecological remediation in mining areas in the future.
