Multi-function vegetation recovery techniques on the land for coal gangue dump in Fushun mining area

Based on the researches of site quality evaluation and plants community succession investigation on land for coal gangue dump (LCGD) in Fushun mining area, the multi-function vegetation recovery techniques were put into effect on LCGD in Fushun mining area. Firstly the standard fields were chosen and the soil environmental factors were investigated. Then the vegetation population distribution was systematically investigated and analyzed so that the suited vegetation populations for recovery were selected and planted on the standard fields. By tests, the key recovery techniques were generalized including artificial planting grass, grass conservation and reforestation. Finally it was found that the afforestation on LCGD improved the ecological environment in Fushun mining area. The improved effects were introduced and discussed. The research results were not only practical meaningful for recovery and recultivation of LCGD in Fushun mining area, but also theoretical meaningful for vegetation recovery of LCGD in other mining areas in China.
