Eco-environment Sensitivity Evaluation of Mining Areas Based on TOPSIS
[Objective] This paper aimed to provide the theoretical basis and technical support for evaluation and management of ecological environment in mining area based on a evaluation case study of the ecological sensitivities of 13 major mining areas in Laiyuan County of Baoding City
Hebei Province.[Methods] PSR model was applied for ecological sensitivity evaluation. And also technique for order preference by similarity to ideal solution(TOPSIS) method was introduced into the evaluation process.[Results] (1) The space layout of the ecological environment quality in Laiyuan County showed a radial incremental feature existed from the southeast to the northwest; (2) In term of the sensitivity difference of the mining area
the ecological environmental sensitivities of township of Tayayi and Dongtuanbao mining were better
and the sensitivity of Wulonggou mining area was worse.[Conclusion] The introduced evaluation of the TOPSIS method for the evaluation of ecological sensitivity of mining area had some obvious advantages. It can make the evaluation process simple
operable and less relayed on the evaluation index number. All of these make the evaluation result more accurate
objective and practical
and furthermore
the results can well describe expound the merits of each mine's ecological level and regional difference.
