Environmental ecosystem services assessment based on urban green infrastructure structure indicators with case study in Shanghai

Abstract

Urban green infrastructure (UGI) attracts much interest because they could provide urban ecosystem services (UES). Among all various methodologies, the UGI structure-based modelling is favored for advantages in physiological mechanisms. This work concerns on environmental services, including "air purification," "microclimate regulation," "noise reduction," "carbon sequestration and storage," and "rainwater retention." A new assessment methodology based on UGI structure indicator was constructed with nine UGI model structures and quantitative values. With implemented in two urban parks in Shanghai, this methodology is speculated to be suitable for patch-level cases, and can make certain efforts to regions without sufficient data.
