Abstract: This study focuses on the iron mining region of Chengde, Hebei province, aiming to explore effective vegetation regeneration techniques for bare rock surfaces. The goal is to provide a scientific foundation for ecological restoration practices in similar mining areas. Experimental trials were conducted on steep exposed rock surfaces to evaluate the effects of different rock-drilling angles and plant species selection. Three drilling angles were tested to assess their influence on vegetation growth. Within the 30°~45° drilling angle range, the growth performance of various plant species was also compared. For gentle slope zones, direct drilling and planting experiments were performed to analyze the growth conditions of different plant types. The research results were as follows. (1) Optimal afforestation on steep rock faces was achieved with drilling angles ranging between 30° and 45° relative to the rock surface. (2) For these steep slopes, planting schemes involving nursery cups—each containing three one-year-old Robinia pseudoacacia seedlings and two Parthenocissus plants, or alternatively, one Platycladus orientalis and two Parthenocissus—achieved an average vegetation coverage of 66% after three years, indicating significant greening effects. (3) On gentler slopes, large Ulmus saplings with soil clumps were directly planted into drilled holes, resulting in 68% vegetation coverage after three years, also demonstrating effective ecological restoration. Based on empirical data and field observations, this study proposes a practical approach to bare rock vegetation regeneration in iron mining areas. The findings offer valuable references for similar ecological restoration projects.
