TITLE：The Mystery of Carbon Source and Sink: the Selection Dilemma of Tree Species in Cities

ABSTRACT：

Environmental stress can affect the carbon source and sink processes of forests. However, there is still a lack of sufficient data support on how urban forests respond to environmental stress at different time scales. Based on 10 years of field survey data, carbon flux observation data, and ecosystem model simulations, detailed tree growth and carbon sequestration capacity are provided, revealing the carbon source and sink dynamics of urban forests in Shanghai and their close relationship with tree species selection and environmental changes. These research results can provide theoretical basis for the selection and reasonable layout of tree species under the Carbon Target, as well as the management of urban forests and the improvement of ecosystem services quality and efficiency.
