This study focuses on the analysis of ecosystem services provided by green spaces
in Bangkok, Thailand, as a potential tool to address urban and environmental problems
there. The analyses are divided into two parts for achieving two objectives, 1) estimating
the magnitude of ecosystem services provided by public street trees, and 2) examining the
relationship between stable isotopic data of tree leaves and the environmental quality of
Bangkok’s streets. The findings could be used to identify tree management issues and
tree species with high potential to mitigate environmental problems through enhancement
of the ecosystem service provision. A combination of field inventories, interviews with
related stakeholders, stable isotopic analyses, remote sensing, geographic information,
and computational models were used in this dissertation.
