Ecological Restoration Of The Environment In Mining Areas Of Economic Theory And Methods Of Evaluation Research

The coal industry has made large contribution for economic development, but it also has paid enormous cost in environment. It is the fact which we have to face to be in front of us: There are obvious disconnection states between economic development and environmental protection, i.e. "two skins" phenomenon which people often say. Why does the phenomenon of "two skins" appear? Its Reasons are in many aspects, and one of the key factors is that we lack one bridge which links the economic system with the environmental system effectively at present. The bridge is economic evaluation of environmental impact.This text has analyzed the economic evaluation of the mining area's ecological restoration project. It has introduced the background, the meanings, the relevant concepts of economic evaluation of environmental impact, it also contains the situation and experience of the domestic and international environmental impact of economic evaluation. At these foundation, it has analyzed the necessity that our country launches economic evaluation of environmental impact, and has classified the environmental impact of the coal construction project:It has expounded the procedure and method of the economic evaluation of the construction project, including assessing the method, environment economic increase and decrease analytical method in environmental value assessment method , environmental loss: Expenses - The analytic approach of benefit, it has designed the index system appraised on this basis, including environmental expense index and environmental economic benefits index. It has made the difference of targets according to expenses and benefit , and has divided the environmental expense index into the index of the direct cost and indirect .The environmental economic benefits index is divided into a direct economic benefits index and indirect economic benefits index : Calculate to all index and then provide the calculation formula of the index, finally does positive research at mining area ecology recover environmental impact of the project economic evaluation.
