Abstract:Evaluating geological environment of Hujiayu copper mining area is essential for regional eco-environment management and sustainable development.Hence, using hierarchy-fuzzy comprehensive evaluation method, this study evaluated multi-factors’ impacts on the geological environment in the area by constructing geological environment evaluation model , and scored each effect degree with fuzzy mathematics. The results show that the geological environment of Hujiayu copper mining area is of medium good grade, consistent with the previous assessments in the area and further indicating the method is practicable for the regional geological environment evaluation. It provides the basis for future environmental restoration and governance in Hujiayu copper mining area, which should focus on the treatments on solid wastes, soil erosion, ground collapse and dust discharge.
