摘要: 喷播技术可有效修复受损山体边坡生态,但受到技术措施和人为因素的影响,边坡土壤理化性质和植被生长状况等存在差异,限制人们对边坡碳汇的理解。该研究分析了团粒喷播技术修复的漳州受损边坡的碳储量特征及其影响因素。结果表明,该边坡碳储量在乔木层、土壤、根系及凋落物层中的分布依次递减,其中乔木层优势树种银合欢对碳储量贡献显著。该边坡土壤层虽薄,但其有机质质量分数达37.98 g/kg,体现出团粒喷播技术提升土壤质量和碳储量的潜力。土壤理化性质,特别是土壤含水量、全磷和全钾对生态修复区碳储量影响显著。该研究明确了土壤水分在生态恢复过程和提升碳汇能力方面的关键作用,对优化边坡治理措施、提高生态修复效果具有重要意义。

Abstract:

Spray-seeding technology can effectively restore the ecological environment of damaged mountain slopes. However,variations in the physicochemical properties of slope soil and vegetation growth conditions—resulting from technical measures and human factors—limit our understanding of carbon sequestration on slopes. This study analyzed the characteristics and influencing factors of carbon storage in damaged slopes in Zhangzhou restored using aggregate spray-seeding technology. The results showed that carbon storage decreased sequentially from the tree layer to soil,root system,and litter layer,with the dominant tree species Leucaena leucocephala in the tree layer contributing significantly to carbon storage. Although the soil layer of the slope is thin,its organic matter content reached 37.98 g/kg,demonstrating the potential of aggregate spray-seeding technology to improve soil quality and carbon storage. The physicochemical properties of the soil,particularly moisture,total phosphorus,and total potassium,significantly affected carbon storage in the ecological restoration area. This study highlights the key role of soil moisture in ecological restoration and carbon sequestration enhancement,providing valuable insights for optimizing slope management measures and improving ecological restoration effectiveness.

Key words: damaged mountain slopes, aggregate spray-seeding technology, ecological restoration, carbon storage
