In oder to determine the dominant plant species and select suitable plant species for ecological restoration, the study area of coal mine wasteland was investigated using field surveys and ecological sampling methods to identify the naturally settled plant species and types of native vegetation. The results indicated that a total of 19 plant species had naturally settled on the coal mine wasteland in the study area, with the largest number of species belonging to the Compositae and Chenopodiaceae families, accounting for 21.05% of the total species, respectively. In terms of life forms, shrub species were the most numerous, making up 52.63% of the total species. Tamarix hohenackeri and Lycium ruthenicum had higher relative density and coverage, and these two species were widely distributed in the area, dominating the surface coverage. Tamarix hohenackeri and Karelinia caspia had the highest importance values in shrub and herbaceous quadrats, respectively, playing a significant role in the restoration and reconstruction of the regional ecosystem. These species can be prioritized for ecological restoration of coal mine wasteland in the study area.
