Identifying the relationship between urban above-ground biomass (AGB) and spatial patterns is vital for optimizing carbon sequestration and enhancing climate resilience in urban areas. However, the influence of urban external morphologies and internal spatial gradients on AGB distribution remains to be systematically elucidated. Using the geometric and population data of the C40 Cities Climate Leadership Group (C40), this study constructed a framework to classify external urban morphologies and delineate internal spatial gradients. AGB data were incorporated to examine its distribution patterns across different morphological types and spatial gradients. Based on the proposed classification framework, 96 C40 cities were classified into five urban morphological types. A compactness- and polycentricity-associated relationship between urban morphology and AGB was observed, and this relationship persisted across specific climatic and geographic zones. Within individual internal spatial gradients, total AGB exhibited a unimodal and a continuously increasing pattern along the geometric and population gradients, respectively. Along the composite gradients, total AGB followed an exponential growth pattern from the urban core to the urban fringe, while its density (AGBD) exhibited a continuous increasing trend that conformed to a quadratic polynomial function. Overall, urban external morphology was associated with the overall magnitude of AGB, while internal spatial gradients further shaped its spatial distribution across different urban zones. This study identified AGB distribution patterns across different urban morphologies and spatial gradients, providing theoretical insights to enhance carbon storage capacity and guide sustainable development in cities worldwide.
