ABSTRACT
With the acceleration of urbanization and the increase in industrial activities, the environmental impact of solid waste landfills has become increasingly significant, and their associated pollution issues have emerged as a key area of global concern. This study focuses on ecological restoration, aiming to explore efficient and sustainable technological approaches to address soil degradation, groundwater contamination, and greenhouse gas emissions caused by landfills. By integrating literature analysis with field investigations, the advantages and disadvantages of existing landfill remediation technologies were systematically evaluated, and a novel ecological restoration model based on plant-microbe synergistic interactions was proposed. This model combines vegetation reconstruction with functional microbial enhancement technologies, reducing leachate pollution while promoting the biological transformation of methane and other greenhouse gases. Experimental results indicate that this technology significantly increases soil organic matter content, improves soil structure, and effectively mitigates the risk of pollutant migration. Compared with traditional methods, it offers the advantages of low cost, environmental friendliness, and ease of implementation. The final conclusion demonstrates that the plant-microbe synergistic restoration technology provides innovative solutions for the ecological recovery of solid waste landfills, contributing to resource recycling and establishing a theoretical and technical foundation for constructing green and low-carbon landfill management systems. This research holds substantial significance for advancing sustainable development in the field of solid waste management.
