ABSTRACT Ecosystem carbon sinks are vital for mitigating global climate change. In the past two decades, Yangtze River Delta (YRD) region has undergone rapid urbanization, with its sink function undergoing significant changes. Understanding spatial evolution patterns and formation mechanisms of ecosystem is critically important. Existing studies often examine single factors, lacking a comprehensive assessment how natural socioeconomic drivers interact through multiple pathways to influence dynamics in rapidly urbanizing regions. This study quantifies YRD from 2000 2020 using Carnegie–Ames–Stanford Approach (CASA) soil respiration model, examines spatiotemporal driving Global Moran's I , hotspot analysis, Mann–Kendall trend structural equation modeling (SEM). The results reveal three key findings: (1) total increased 69.91 million tons (Mt) 103.75 Mt, high‐value areas concentrated mountainous regions characterized by favorable climatic conditions dense vegetation, low‐value located east, primarily due reduced ecological resource area fragmented structures built‐up land expansion; (2) Carbon functions improved across 68.45% region, particularly where vegetation matured, but declined 15.67% mainly urban (3) SEM indicates that normalized difference index (NDVI) forest proportion (PF) enhance functions, while (PBL), driven population economic growth, primary negative factor. underscores importance preserving integrity managing expansion sustain offering scientific insights into balancing conservation development worldwide.

Urban parks, a type of urban green space, help mitigate environmental pollution and climate change by absorbing storing atmospheric carbon. Optimizing their carbon-sink capacity requires thoughtful plant community design considering multiple factors. This study analyzed South Korean parks using QGIS i-Tree Eco, integrating satellite imagery with field surveys at both spatial tree scales. Park spaces were classified into six types based on the biotope criteria established in this study. Random forest regression was applied to each identify key variables influencing annual carbon sequestration storage. The relationship between maturity examined for ten dominant species, offering insights selection. Higher coverage more deciduous species linked efficiency While variable importance varied slightly across types, density most influential sequestration, diameter breast height age These findings provide integrated short-term long-term storage, as well strategic directions structuring communities ecosystems. offers empirical evidence designing carbon-efficient contributing sustainable landscape strategies.
