Abstract：In order to screen pioneer species for vegetation restoration in waste rock field of iron ore in the east of Hebei province ,field afforestation experiment was used to compare survival rate , shoot increment ,vegetation coverage ,growth vigor of nine arbor species and shrub species ,and the comprehensive advantage values were analyzed .The results showed that different pioneer species were screened for vegetation restoration from different factors :the survival rates of Robinia pseudoacacia L ., Ulmus pumila L .and A ilanthus altissima(Mill .) Swingle were higher than the other species ,the shoot increments of Ulmus pumila L .,Forsythia suspense ,Rhus typhina Nutt .and Robinia pseudoacacia L . were higher than the others ,the vegetation coverage of Rhus typhina Nutt .,Ulmus pumila L .,Robinia pseudoacacia L .and A ilanthus altissima (Mill .) Swingle were higher than the others .,Robinia pseudoacacia L .and Ulmus pumila L .thrived in the waste rock field ;the comprehensive advantage values of the experimental plant species followed the sequence :Ulmus pumila L .(1 .07)> Robinia pseudoacacia L .(1)> Rhus typhina Nutt .(0.91)> Ailanthus altissima(Mill .) Swingle(0.81)> Forsythia suspensa (0.78)> Prunus davidiana(0.57)> Syzygium aromaticum (0.50)> Hibiscus syriacus L .(0.35)>Prunus sibirica (0.33 ) .Overall ,Ulmus pumila L .,Robinia pseudoacacia L .,Rhus typhina Nutt ., A ilanthus altissima(Mill .) Swingle were the suitable pioneer plant species for re-vegetation in the waste rock field of iron ore .
