Construction of carbon sequestration ecological network in Linyi City based on supply and demand of eco-system service
摘要
Abstract
The increasing carbon emissions is one of the important reasons for global warming.As a key area of car-bon emissions,carbon sequestration capacity of cities is urgently needed to be improved.Carbon sequestration ser-vices can be transferred between supply and demand areas due to the circulation of atmosphere.With Linyi City as an example,we used the minimum cumulative resistance model to extract the matching path of supply and demand,and constructed a carbon sequestration ecological network.The results showed that the regions with high supply of carbon sequestration services were located in the north and south of the study area,and that current total supply could solve about 60％of the total demand.Although the spatial distribution of supply and demand was uneven,54％of the areas that could meet the surrounding carbon sequestration demand were still idle.The optimized sup-ply-demand matching paths could maintain good transmission efficiency of material and energy,with lower costs.Paths with strong potential carbon sequestration capacity were located in the central and northwest part of the re-search area.In the construction of carbon sequestration ecological network,it is necessary to strengthen the protec-tion and restoration of the supply side of carbon sequestration services,realize carbon reduction and strengthen car-bon sequestration on the demand side,and optimize the matching path of supply and demand.This method provided services to the demand areas through the oversupply of ecosystem services,optimized the overall resource alloca-tion,which could advance regional carbon sequestration capacity.关键词
