Ecological Mechanisms of Carbon Sinks in Soil and Water Conservation
The carbon pool of terrestrial ecosystems is not permanently stored,but highly de-pendent on changes in external environmental conditions.Soil erosion control measures can effec-tively regulate the carbon sequestration capacity in project areas.This study analyzes the ecological mechanisms of carbon sinks in soil and water conservation from three aspects:external carbon addi-tion,internal carbon addition,and erosion and emission reduction.The findings show that soil and water conservation measures can promote the synergistic effects of soil mineral and microbial carbon pumps,alleviate limiting factors on individual vegetation,achieve a new ecological balance,re-duce soil erosion,lower carbon emissions,and enhance carbon sequestration capacity.This re-search further refines the analysis of the benefits of soil and water conservation measures in various regions and types,focusing on soil conservation,carbon sequestration,erosion reduction,emis-sion reduction,and increased greening and carbon sink capacity.It provides technical support for the development of carbon sink-based soil and water conservation projects or negative-carbon soil and water conservation technologies.
