Resumen

La dinámica de dióxido de carbono-carbono (C-CO2) a gran escala de los bosques urbanos subtropicales y otros tipos de infraestructura verde y gris se exploraron en un campus urbanizado cerca de Shanghai, China. Integramos mediciones de flujo de C-CO2 en la covarianza eddy (EC) y la herramienta de huella Agroscope Reckenholz-Tänikon para analizar la dinámica de C-CO2 a escala de paisaje, así como en parches forestales urbanos a escala local durante un año. El enfoque midió el flujo de C-CO2 de diferentes áreas contribuyentes dependiendo de las direcciones del viento y la estabilidad atmosférica. Aunque el panorama del estudio era una fuente neta de carbono (2.98 Mg C ha − 1 año − 1), encontramos que el flujo medio de CO2 en los parches de bosques urbanos fue de −1.32 μmol m − 2s − 1, lo que indica que estos parches funcionan como un sumidero de carbono con un balance anual de carbono de −5.00 Mg C ha − 1. Estos resultados indican que los parches de bosque urbano y la composición de vegetación (es decir, infraestructura verde) pueden diseñarse para maximizar el secuestro de CO2. Este novedoso enfoque de modelado integrado se puede utilizar para facilitar el estudio de los efectos a gran escala de los bosques urbanos y la infraestructura verde en el CO2 y para establecer diseños de planificación y plantación con bajas emisiones de carbono en los subtropicos.

abstract = "The multi-scale carbon-carbon dioxide (C-CO2) dynamics of subtropical urban forests and other green and grey infrastructure types were explored in an urbanized campus near Shanghai, China. We integrated eddy covariance (EC) C-CO2 flux measurements and the Agroscope Reckenholz-T{\"a}nikon footprint tool to analyze C-CO2 dynamics at the landscape-scale as well as in local-scale urban forest patches during one year. The approach measured the C-CO2 flux from different contributing areas depending on wind directions and atmospheric stability. Although the study landscape was a net carbon source (2.98 Mg C ha-1 yr-1), we found the mean CO2 flux in urban forest patches was -1.32 μmol m-2s-1, indicating that these patches function as a carbon sink with an annual carbon balance of -5.00 Mg C ha-1. These results indicate that urban forest patches and vegetation (i.e., green infrastructure) composition can be designed to maximize the sequestration of CO2. This novel integrated modeling approach can be used to facilitate the study of the multi-scale effects of urban forests and green infrastructure on CO2 and to establish low-carbon emitting planning and planting designs in the subtropics.",
