Model Calculation and Analysis of Geological Environmental Capacity in Qian'an Mining District

Abstract

This paper puts forward environmental bearing capacity relative surplus rate and calculation model based on the theory of environmental bearing capacity, Through collecting and estimating the predictive value and ideal value of each index in different development stages and schemes, using analytic hierarchy process to established the target weight, environmental bearing capacity relative surplus rate of the rule layer and index level in Qian’an Mining area are calculated through the gradual convergence principle, accordingly the optimal solution to improve the environmental bearing capacity of Qian’an mining area is determined ,which provides scientific basis for promoting to realize the sustainable development of Qian’an Mining area.
