Abstract: The pollution and damage of mining ecological environment has become an important factor to impact on China's economic and social development.Based on the dissipative structure theory,the author of this paper anlayzes the evolution mechanism of dissipation stucture of mining ecosystem.An index system of positive entropy and negative entropy is proposed in this paper.Using the entropy value principle to quantify the positive and negative entropy of the environmental protection of mines.In addition,the Brusselator model of mine ecological and environmental protection systems is established thoughtranslating the variables in Brusselator model,meanwhile,a method for judgingthe dissipative structure of mines is derived.Finally,one mining has been chosen as the subject to be exemplified.
