Vertical evaluation of air quality improvement by urban forest using unmanned aerial vehicles

Abstract: Urban forest is considered an effective strategy for mitigating urban air pollution via deposition, absorption and dispersion processes. However, previous studies had focused mainly on the deposition effect or removal capacity near the ground, while the net effect of the urban forest on air quality is rarely evaluated in the vertical dimension. In this study, PM2.5 (particulate matter with diameter less than 2.5), PM10 (particulate matter with diameter less than 10 μm), carbon monoxide (CO), sulfur dioxide (SO… Show more

“…An increasing number of urban residents are walking in urban forests to experience nature and relieve stress. At present, a large number of studies have provided evidence that the urban forest environment is beneficial to health (Barthod and Fournier 2019;Carnicer et al 2021;Miao et al 2022). For example, the forest environment can help people reduce stress and restore their attention.…”

“…The general uncertainty associated with carbon pool valuation in urban areas is estimated to be 30%-50% higher than the average value (IPCC, 2006). Consequently, there is an urgent need for the development of practices for testing and classifying carbon sinks in urban parks, particularly with regard to high-precision detection of trees, shrubs, and grass coverages (Miao et al, 2022).…”
