Change of Ecological Safety in Mining Area Based on Grey Entropy Model

摘要：

The ecological safety is new concept for safety field, and has been one of the hottest topics for research. The ecosystem in mining area is damaged by mining activities, and the sustainable development is disturbed. So it is necessary to assess and monitor the state of ecological safety in mining area to produce a friendly environment for regional development. The index system for ecological safety in mining area was established with Pressuro-State-Response model based on the practical status, and then the change of ecological safety was analyzed with the help of grey entropy. The research demonstrates that the ecological safety in research area was aggravating, and measures shall be taken to modify the environment. The research reflects that the grey entropy is a tool to study ecological safety.
