Systems theory highlights that stand structural attributes influence overall functioning. However, the relationship between these attributes and ecosystem multifunctionality, particularly in urban forests, remains poorly understood. This study uses regression analysis and a random forest model to assess the effects of 19 indicators of stand structure characteristics on ecosystem multifunctionality of urban forests in Changchun, a representative forest city in northern China. The structural characteristics are categorized into stand structure, herbaceous layer structure, and structural heterogeneity. Multifunctionality is evaluated based on carbon sequestration, rainfall interception, air temperature reduction, humidity enhancement, PM2.5 reduction, and noise reduction. Results indicate that both stand structural heterogeneity and stand density significantly enhance multifunctionality, with structural heterogeneity having the greatest impact, followed by stand structure and herbaceous cover. Thus, optimizing stand density, increasing structural heterogeneity, and maintaining sufficient herbaceous cover are crucial for improving urban forest multifunctionality. These findings offer important implications for urban forest management and the enhancement of urban environmental quality.
