Studying on the eco-environment remediation system in mining area based on adaptive management

The purpose of eco-environmental remediation in mining areas is to reduce the health risk or ecological risk of damaged ecological environment to an acceptable risk level through artificial renovation and reconstruction.To realize the goal of coordination between artificial ecosystem and natural ecosystem, it is necessary to use adaptive management to track the remediation status, evaluate the objectives of the stage, and adjust and perfect the remediation measures.In combination with practice, this paper proposes a scheme to optimize the ecological environment restoration system from the following aspects:according to the acceptable risk level, the general requirements of ecological environment remediation in mining areas should be set reasonably, and the bottom line of behaviors should be drawn for activities nationwide; the worst case analysis is used as the carrier to promote the operator to independently identify the possibility of ecological environmental damage and risk, propose countermeasures, and ensure its implementation with social supervision; on the basis of ecological and environmental quality damage and ecosystem service value assessment, dynamic monitoring results assessment, restoration plan adjustment and supervision mechanism should be established.
