چکیده انگلیسی
A mathematical model is constructed for quantifying urban trees' effects on mitigating the intensity of ultraviolet (UV) radiation on the ground within different land use types across a city. The model is based upon local field data, meteorological data and equations designed to predict the reduced UV fraction due to trees at the ground level. Trees in Seoul, Korea (2010), produced average UV protection factors (UPF) for pedestrians in tree shade at solar noon (May to August) of 8.3 for park and cemetery land uses and 3.0 for commercial and transportation land uses. The highest daily UPF was 11.8 in the park and cemetery land uses, which has the highest percent canopy cover. This UV model is being implemented within the i-Tree modeling system to allow cities across the world to estimate tree effects on UV exposure. Understanding the impacts of urban trees on UV exposure can be used in developing landscape design strategies to help protect urban populations from UV exposure and consequent health impacts.
