Comprehensive restoration practices specific to southern ion-adsorption rare earth mining areas highlighted in Zhixing Seminar Series

 On March 26, 2026, at 14:30, NCU School of Life Sciences successfully convened the 15th seminar of Zhixing Seminar Series, a flagship event series of the school, in Room A212 of the Life Sciences Building. The event featured an academic presentation titled "Restoration Practices for Southern Ion-Adsorption Rare Earth Mines Based on Ecological Succession", delivered by Associate Professor Yizhen Liu and hosted by Professor Daxian Zhao, Deputy Dean of the School.

The restoration of rare earth mines represents a national priority of significant strategic value. A primary challenge in this field involves persistent contamination within mining areas and the degradation of soil physicochemical properties. Professor Liu presented his team's decade-long ecological restoration practices and monitoring in southern ion-adsorption rare earth mining regions. Focusing on core technologies and practical pathways, he elaborated on strategies for aboveground and belowground species selection; the construction of synthetic communities tailored to distinct restoration stages, including plant, biological soil crust, and microbial assemblages; and an integrated mining-leaching-restoration pathway aligned with green mine standards. These efforts have culminated in a comprehensive restoration model specific to southern ion-adsorption rare earth mining areas.

The subsequent interactive session facilitated vigorous discussion regarding critical issues such as mine contamination, agricultural product safety, species selection challenges, invasive species control, cost management, and long-term monitoring strategies. Drawing upon his extensive research experience, Professor Liu provided detailed responses to each inquiry, offering valuable insights and practical reflections derived from the restoration process.
