Carbon sink service (CSS) is crucial in addressing global warming and provides theoretical support for research on human‒system coupling. CSS generation, flow, utilization the composite ecosystem of mountains, rivers, forests, farmlands, lakes, grasslands (CEMRFFLG) sustainable development. Quantifying coupled supply‒flow‒demand processes mechanisms CEMRFFLG remains a pressing issue study carbon flows (CSSFs). First, quantify supply demand situation Chongqing. Second, coupling process CSSF among water, forest, farmland, grassland subsystems explored via breakpoint model combined with metacoupling framework. Finally, multiscenario simulation was performed to reveal its flow mechanism. The results show that: (1) Net primary productivity (NPP) mainly comes from emissions (CEs) come farmland. (2) During telecoupling, forest subsystem has highest total value outflow inflow plots, accounting 35.51% 61.24% total, respectively. (3) moves areas human activities. This paper proposes optimization suggestions essential achieving complex ecosystem's
