Urban Green System Planning Insights for a Spatialized Balance between PM10 Dust Retention Capacity of Trees and Urban Vehicular PM10 Emissions

Reducing air pollution is a crucial challenge in urban areas. In this regard, green infrastructures could play pivotal role. the literature, scholars analyzed both ability of species-specific and layout-specific to reduce best location sites new increase provision overall ecosystem services. There lack studies helping planners designers choose where which infrastructure implement based on vegetation performance differentiated demand for services city This paper uses tree cadastre data from medium-sized central Italy (Perugia) traffic open-layers Gmaps develop spatial analysis trees’ PM10 dust retention, produced by vehicular emissions, respectively. The method generates spatialized balance between (air-polluted traffic) supply (PM10 retention trees) support local decisions about locations choice species. 6710 trees an area 42.62 km2 with linear road density 15 km/km2.
