Research on carbon balance in the soil conservation ecological function zone of dabie mountains and rivers from the perspective of carbon fixation service supply and demand
Using the Dabieshan Mountains and Soil Conservation Ecological Function Area as a case study,this research examines the spatio-temporal variations in regional carbon balance from 2000 to 2020.The InVEST model is employed to quan-tify carbon sequestration services,while the IPCC list method and population density method are utilized for assessment.The findings reveal that land use changes within the study area during the specified period exhibit significant local alterations but in-significant overall modifications.The total supply of carbon sequestration services exceeds the total demand,with woodland ar-eas characterized by minimal human activities serving as high-value regions for carbon supply.Conversely,construction land associated with robust economic activities represents high-value areas for carbon demand.A spatial mismatch is observed in terms of carbon sequestration services,indicating surplus conditions in central and eastern regions alongside deficits in western regions.Carbon balance demonstrates an overall improvement pattern combined with localized deterioration tendencies.Eleva-tion and precipitation display strong correlations with the provision of carbon sequestration services,whereas population density and GDP show close associations with demand levels.These outcomes provide valuable insights for future spatial optimization of land use practices and achieving dual-carbon goals within this specific study area.
