碳排放的加剧是全球变暖的重要原因之一，城市作为碳排放的重点区域急需提升整体固碳能力。固碳服务可在供给与需求区域之间依靠大气的流通实现相邻区域间生态系统服务的转移。本研究以临沂市为例，应用最小累积阻力模型提取供需匹配路径并进行固碳生态网络的构建。结果表明:研究区域固碳服务供给量较高的区域位于北部和南部，现有供给总量约可解决60％的需求总量;供需空间分布不平衡，仍有54％的可解决周边固碳需求的区域被闲置;优化供需匹配路径能保持较好的物质能量传播效率，成本较低，潜在固碳能力较强的路径位于研究区中部和西北部。在固碳生态网络的建设中，需加强固碳服务供给端的保护与修复，实现固碳服务需求端的减碳排与强固碳，并做到供需匹配路径的优化与协调。该方法通过生态系统服务供给过剩区域为周边高需求区域提供服务，优化整体资源配置，可提升区域固碳能力。
Construction of carbon sequestration ecological network in Linyi City based on supply and demand of eco-system service
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.
