Resumen

Los estudios han documentado muchos factores biofísicos que están correlacionados con el almacenamiento de carbono en los bosques urbanos. Esta función de los bosques urbanos también se promueve cada vez más como una solución basada en la naturaleza para las ciudades. Si bien la urbanización afecta tanto a la estructura como a la función de los ecosistemas forestales urbanos, son escasos los análisis cuantitativos de los impulsores ocasionales específicos del almacenamiento de carbono en los bosques urbanos frente a los periurbanos. Para abordar esta falta de información, utilizamos datos de campo de parcelas aleatorias ubicadas a lo largo de un gradiente de urbano a rural en Shangai, China, ecuaciones de biomasa específicas de la región, y análisis de trayectoria de factores socioeconómicos y ecológicos del bosque urbano comúnmente estudiados para analizar sus efectos sobre el almacenamiento de carbono en árboles sobre la superficie. También se elaboró un índice de urbanización para diferenciar cuantitativamente los sitios urbanos de los periurbanos a lo largo del transecto. Los resultados muestran que tanto en los bosques urbanos como en los periurbanos, el porcentaje de cobertura arbórea y arbustiva tuvo un efecto significativo y positivo en el carbono de árboles y arbustos, pero la densidad de árboles y arbustos tuvo un efecto aún mayor. Además, la diversidad de especies de árboles y arbustos no tuvo efectos sobre el almacenamiento de carbono, mientras que los efectos de la composición de las especies sobre el carbono de árboles y arbustos en los bosques urbanos fueron diferentes de los de las zonas periurbanas. Los bosques periurbanos también mostraron un efecto significativo del porcentaje de cobertura de árboles y arbustos en la diversidad de especies de árboles y arbustos. Este enfoque, que utiliza un análisis de la trayectoria de los datos de campo y de las parcelas y de la información dendrométrica y de urbanización específica del lugar, puede utilizarse para identificar cuantitativamente las dependencias causales poco exploradas entre los generadores de cambio y los servicios de los ecosistemas, sin depender exclusivamente de los datos sobre la cubierta terrestre espacial, que a menudo no están disponibles en los países en desarrollo.

abstract = "Studies have documented many biophysical factors that are correlated with urban forest carbon storage. This urban forest function is also increasingly being promoted as a nature-based solution for cities. While urbanization affects both the structure and function of urban forest ecosystems, quantitative analyses of specific casual drivers of carbon storage in urban versus periurban forests are scarce. To address this lack of information, we used field data of random plots located along an urban to rural gradient in Shanghai, China, region-specific biomass equations, and path analysis of commonly studied urban forest socioeconomic and ecological drivers to analyze their effects on above ground tree carbon storage. An urbanization index was also developed to quantitatively differentiate urban from peri-urban sites along the transect. Results show that in both urban and peri-urban forests, percent tree and shrub cover had a significant and positive effect on tree and shrub carbon, but tree and shrub density had an even greater effect. Further, tree and shrub species diversity had no effects on carbon storage, while the effects of species composition on tree and shrub carbon in urban forests was different from those in peri-urban areas. Peri-urban forests also exhibited a significant effect of percent tree and shrub cover on tree and shrub species diversity. This approach, using a path analysis of field and plot data and site-specific dendrometric and urbanization information, can be used to quantitatively identify little explored causal dependences between drivers and ecosystem services without relying exclusively on spatial land cover data often not available in developing countries.",
