To evaluate the potential of Sedum in vegetation restoration of abandoned metal mining areas, the S. hybridum‘Immergrunchen’and S. spurium ‘Coccineum’were used as materials to study their adaptability by growth indexes condition in the abandoned iron mine soil(including mining soil, dump soil, tailing sand) by pot experiment within two growing seasons, and correlation analysis and canonical correspondence analysis were used to discuss the main soil physicochemical properties that affecting Sedum growth. The results showed that the abandoned soil significantly affected the survival rate of two Sedum species in the second growing season. The soil survival rates of the two Sedum species in mining area, dump soil and tailings soil were 40%~66%, 68%~90%, 33%~46% respectively. Different abandoned soils had significant inhibitory effects on the growth indexes of the two species. S. hybridum‘Immergrunchen’could be used as the recommended variety for the restoration of mining areas and S. spurium‘Coccineum’could be used for the dumps. Aerated porosity and soil water content were the main factors affecting the Sedum growth, 12.4% and 8.6% respectively.

Key words: Sedum, abandoned mine, plant growth condition, physicochemical properties of soil, CCA analysis
