[Method] Taking Jinjie mining area as study object, based on RS and GIS technology, ecological sensitivity in Jinjie mining area was assessed comprehensively from the aspects of soil erosion, desertification and geological disaster by means of multivariate weighted stack method. [Result] Most of Jinjie mining area belonged to extremely high sensitive or high sensitive area which accounted for 73.35% of total area, with little moderate sensitive (19.50%), low sensitive (0.96%) and non-sensitive area (6.19%); the unreasonable development of mineral resources would damage its ecological environment severely. [Conclusion] The study could provide theoretical foundation for the protection of ecological environment in mining area.展开更多
