Abstract To select tree species and reclamation measures suitable for gangue waster land, the effects of different reclamation measures on plant growth and soil chemical properties in gangue waste land were studied in Fushun of Liaoning province. The results showed that the survival rate of different plants ranged from 21% to 85%, in which that of Ulmus pumila and Astragalus adsurgens was 81% and 85% respectively and that of Populus simionii, Robinia pseudoacacia and Koelreuteria panaiculata was about 70%. They were suitable to the gangue waste land environment. Vegetation can improve the contents of organic matter, total N, total P and total K in different soil layers, but the degree of improvement varied with soil layers and nutrient varieties. Biological compound fertilizers, biopreparate, water retention agent were utilized together which can improve the growth of the main tree species.
