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.

Highlights

More than half of the world’s population currently lives in urban areas, where growth of most of future global population will take place; urban areas will become the focus of future studies [1]
Using the actual Urban green infrastructure (UGI) structure models during the field survey conducted from September to December in 2014, we identified all the land uses in those two parks; in addition, data on land size was collected using GIS mapping
This study focused on physiological mechanisms, and urban ecosystem services (UES) assessment modelling methodology based on UGI structural indicators is constructed

Summary

Introduction

More than half of the world’s population currently lives in urban areas, where growth of most of future global population will take place; urban areas will become the focus of future studies [1]. Environmental deterioration is a major challenge in urban areas, and being the main habitat supporting a dense population and intense human activities, urban ecosystems suffer from severe air and noise pollutions [2] and other environmental problems, including urban heating and flooding caused by global climate change [3]–[5]. Owing to the direct interactions with UGI and human activities [8], urban ecosystem services (UES) assessment has become a major concern. UES is basically classified into services including support, regulation, provisioning, and cultural services [9], and a standardized methodology in UES assessment remains lacking [10] because of the varying back-grounds of researchers [11]
