The invention discloses a pollution type slope with pollution isolation and ecological greening functions and a method. The pollution type slope with the pollution isolation and ecological greening functions comprises a pollution type slope body, suture lines, longitudinal supporting ropes, steel rope anchor rods and transverse supporting ropes. The longitudinal supporting ropes and the transversesupporting ropes are laid longitudinally and transversely and connected through the steel rope anchor rods, so that a safety protection frame is formed, and the flattened pollution type slope body isdivided into a plurality of treatment areas. A pollution isolation layer, a greening layer, a support layer and a steel wire net are sequentially laid on each treatment area. The steel wire nets arefixed to the safety protection frame through the suture lines. According to the pollution type slope with the pollution isolation and ecological greening functions, the pollution type slope can be greened while being treated, and the ecological system is reconstructed; and the pollution type slope with the pollution isolation and ecological greening functions is suitable for metal mines and opencast coal mines and can serve as other types of slopes with high seepage-proof requirements.
