In Chongqing's composite ecosystem of Mountains, Rivers, Forests, Farmlands, Lakes, and Grasslands (CEMRFFLG), the embodied carbon of four subsystems (farmland, grassland, forest, and water) was quantified using Multi-Regional Input-Output (MRIO) and Partial Least Squares Structural Equation Modeling (PLS-SEM) approaches. The flows of embodied carbon among these subsystems were analyzed within a metacoupling framework, and their driving mechanisms were systematically explored. The results indicated that: (1) In 2020, embodied carbon of CEMRFFLG subsystems in Chongqing ranked as farmland > grassland >forest > water, with the farmland subsystem accounting for 68.88% of the total; (2) The embodied carbon inflow to the CEMRFFLG of Chongqing was 3.45 times greater than its outflow, exhibiting a distinct net-input characteristic; (3) Direct carbon flows were characterized by inflow and outflow contribution rates from distant systems of 99.28% and 78.82%, respectively, indicating predominance of long-distance transmission. Conversely, embodied carbon flows presented a distinctive structural pattern of "remote inflows and proximate outflows," wherein distant systems contributed 85.61% of inflows and adjacent systems received 91.36% of outflows; (4) Among all factors, the consumption level showed the strongest positive influence on embodied carbon flows of CEMRFFLG, with a path coefficient of 0.845. A comparative analysis of direct and embodied carbon flows provides a scientific basis for optimizing embodied carbon flow reduction strategies in Chongqing's CEMRFFLG, offering significant implications for achieving green development of composite ecosystem patterns.

通过MRIO和PLE-SEM模型,测算重庆市山水林田湖草复合生态系统(CEMRFFLG)四个子系统的隐含碳,分析各子系统间在元耦合框架下的隐含碳流动,并探究隐含碳流的影响机制.结果表明:(1)2020年重庆市的CEMRFFLG的子系统中隐含碳排序为田>草>林>水,田子系统占比为68.88%.(2)重庆市的CEMRFFLG的隐含碳流入量是流出量的3.45倍,呈现出显著的“净输入型”特征.(3)直接碳流的远程系统流入量贡献率达99.28%,流出量贡献率达78.82%,呈现远距离传输为主的特征;隐含碳流则呈现出“远程输入、近程输出”的结构性特征,远程系统的流入量贡献率为85.61%,近程系统的流出量贡献率为91.36%.(4)消费水平对CEMRFFLG的隐含碳流具有最强的正向影响,路径系数为0.845.对直接碳与隐含碳进行分析比较,为重庆市的CEMRFFLG隐含碳流减排优化建议提供科学依据,为实现生态系统复合格局的绿色发展具有重要意义.

通过MRIO和PLE-SEM模型,测算重庆市山水林田湖草复合生态系统(CEMRFFLG)四个子系统的隐含碳,分析各子系统间在元耦合框架下的隐含碳流动,并探究隐含碳流的影响机制.结果表明:(1)2020年重庆市的CEMRFFLG的子系统中隐含碳排序为田>草>林>水,田子系统占比为68.88%.(2)重庆市的CEMRFFLG的隐含碳流入量是流出量的3.45倍,呈现出显著的“净输入型”特征.(3)直接碳流的远程系统流入量贡献率达99.28%,流出量贡献率达78.82%,呈现远距离传输为主的特征;隐含碳流则呈现出“远程输入、近程输出”的结构性特征,远程系统的流入量贡献率为85.61%,近程系统的流出量贡献率为91.36%.(4)消费水平对CEMRFFLG的隐含碳流具有最强的正向影响,路径系数为0.845.对直接碳与隐含碳进行分析比较,为重庆市的CEMRFFLG隐含碳流减排优化建议提供科学依据,为实现生态系统复合格局的绿色发展具有重要意义.

山水林田湖草复合生态系统  /  隐含碳流  /  元耦合  /  MRIO模型  /  PLE-SEM模型

In Chongqing's composite ecosystem of Mountains, Rivers, Forests, Farmlands, Lakes, and Grasslands (CEMRFFLG), the embodied carbon of four subsystems (farmland, grassland, forest, and water) was quantified using Multi-Regional Input-Output (MRIO) and Partial Least Squares Structural Equation Modeling (PLS-SEM) approaches. The flows of embodied carbon among these subsystems were analyzed within a metacoupling framework, and their driving mechanisms were systematically explored. The results indicated that: (1) In 2020, embodied carbon of CEMRFFLG subsystems in Chongqing ranked as farmland > grassland >forest > water, with the farmland subsystem accounting for 68.88% of the total; (2) The embodied carbon inflow to the CEMRFFLG of Chongqing was 3.45 times greater than its outflow, exhibiting a distinct net-input characteristic; (3) Direct carbon flows were characterized by inflow and outflow contribution rates from distant systems of 99.28% and 78.82%, respectively, indicating predominance of long-distance transmission. Conversely, embodied carbon flows presented a distinctive structural pattern of "remote inflows and proximate outflows," wherein distant systems contributed 85.61% of inflows and adjacent systems received 91.36% of outflows; (4) Among all factors, the consumption level showed the strongest positive influence on embodied carbon flows of CEMRFFLG, with a path coefficient of 0.845. A comparative analysis of direct and embodied carbon flows provides a scientific basis for optimizing embodied carbon flow reduction strategies in Chongqing's CEMRFFLG, offering significant implications for achieving green development of composite ecosystem patterns.
