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
