Abstract: In order to quantitatively evaluate ecological security current status in metal mines, the evaluation index system and evaluation grading criterions of ecological security effect in metal mines were created. Weights of evaluation subsystem and secondary indexes were obtained by the fuzzy analytical hierarchy process(FAHP). An evaluation integrated model was built for ecological security effect in metal mines on the basis of FAHP and variable fuzzy sets. The model was applied to evaluate ecological security effect for a large copper mine in Anhui province. Through the calculation of the model, the ecological security effect grade of production effect, natural endowment effect and socioeconomic effect was classified as class Ⅱ; the environmental effect subsystem was classified as class Ⅲ. The overall evaluation of the copper mine was classified as class Ⅱ. The results show that the model is reliable and flexible and its results are consistent with the actual situations and those of other models.

Key words: fuzzy analytical hierarchy process(FAHP), variable fuzzy sets, ecological security effect of mines, evaluation index system, relative difference function
