Abstract: The normal cloud model is introduced to avoid the problems of randomness and ambiguity in the process of ecological security evaluation. This paper constructs an ecological security evaluation index system based on the pressure-state-response(PSR) model, uses the entropy method to determine the weight of each indicator, dynamically evaluates the ecological security status of nine mining cities in Anhui from 2010 to 2018, and combines the BP neural network algorithm to forecast the development status in the next seven years. The results show that from 2010 to 2018, the overall ecological security of mining cities in Anhui has been upgraded from level Ⅲ to level Ⅳ; there are differences in the development of various mining cities, and the ecological security of Huainan is poor; in the next seven years, the ecological security of mining cities in Anhui Province is on the rise, and the pressure and state subsystems belong to a lower level.
