By analytical model based on the patch-corridor model in landscape ecology, the quantitative benchmark data of the mining brownfield ecological restoration is deduced, and it would be become unbroken red line in the planning design. The forest area for ecological species perching can’t be less than 1.5 km², and the area less than 30 km² should be mainly used for afforestation. The natural state of the site boundary should be kept, the shape index should be added and the fences should not be built. The width of ecological corridor should not be less than 60 m, the pollution sources such as tailing heap and so on should be covered by vegetation, and the width of buffer strips can’t be less than the minimum allowable value. All of these could become theoretical foundation in the project design, thus, we could ensure the mine parks based on mining brownfields become genuine ecological civiization construction project, and could prevent predatory secondary development.
