The Analytic Hierarchy Process method is a comprehensive evaluation method that combines qualitative and quantitative analysis. In this paper, by using Analytic Hierarchy Process method, the impact of gold mining activities on geological environment in Jiudian town in Pingdu city has been evaluated, and a classification of the degree of impact on geological environment of mines has been obtained. Based on field conditions, the influencing factors of geological environment in the gold mining area have been analyzed, and an evaluation index system has been established. By using Analytic Hierarchy Process method, the weight of each evaluation index has been determined. Through data analysis, field surveys, threedimensional drone photography, and soil and water environmental testing, evaluation indices have been determined. By using comprehensive weighted index evaluation method, evaluation areas can be divided into areas with severe, relatively severe and light impacts on geological environment of mines. It will provide recommendations for subsequent conservation and rehabilitation efforts of geological environment in mines.
