“…Urban green spaces (UGS) contribute significantly to quality of life [1,2] and sustainable development in cities [3] because they can deliver multiple ecosystem services to urban inhabitants [4,5]. UGS can regulate climate [6][7][8], remove air pollution [9], reduce stormwater run-off [10], provide recreational opportunities [5], and improve public health [11]. For example, the urban forest in Beijing could remove 772 tons of particulate matters annually [9].…”

The structure of urban green spaces (UGS) plays an important role in determining the ecosystem services that they support. Knowledge of factors shaping landscape structure of UGS is imperative for planning and management of UGS. In this study, we assessed the influence of urban form on the structure of UGS in 262 cities in China based on remote sensing data. We produced land cover maps for 262 cities in 2015 using 6673 scenes of Landsat ETM+/OLI images based on the Google Earth Engine platform. We analyzed the impact of urban form on landscape structure of UGS in these cities using boosted regression tree analysis with the landscape and urban form metrics derived from the land cover maps as response and prediction variables, respectively. The results showed that the three urban form metrics—perimeter area ratio, road density, and compound terrain complexity index—were all significantly correlated with selected landscape metrics of UGS. Cities with high road density had less UGS area and the UGS in those cities was more fragmented. Cities with complex built-up boundaries tended to have more fragmented UGS. Cities with high terrain complexity had more UGS but the UGS were more fragmented. Our results for the first time revealed the importance of urban form on shaping landscape structure of UGS in 262 cities at a national scale.

“…prior to the dedicated measurement period in order to allow sensors to stabilize. The stations allow us to record all meteorological parameters that infl uence the human energy budget (Takács, Á. et al 2016b). However, since this study is focusing on the shading capacity of trees, we analyze the changes of one parameter only.…”

This study aims to determine the solar permeability characteristics of some common urban tree species in Hungary and to analyse their shading effi ciency in mostly clear sky conditions. The results are based on a measurement-series implemented during the whole vegetation period in 2015. This paper compares diff erent tree species regarding their transmissivity, and looks for diff erences between diff erent sized tree individuals belonging to the same species. The following order was found among the investigated species regarding their shading-capacity: T. cordata, A. hippocastanum and S. japonica. Additionally, higher transmitt ed radiation and consequently higher transmisivity values were detected in the case of the smaller investigated A. hippocastanum.

ResumoAs ações humanas têm contribuído nas mudanças térmicas nos ambientes urbanos em escala microclimática através de tipos de revestimentos que possuem propriedades de armazenarem e transmitirem energia. Umas das estratégias de melhorar termicamente as cidades é a implantação da arborização. Assim, o objetivo deste estudo foi analisar o efeito do sombreamento arbóreo na temperatura superficial e no fluxo de energia de diferentes coberturas urbanas nos períodos seco e chuvoso na cidade de Cuiabá-MT. Como referencial foi utilizado um local sem arborização com esses mesmos revestimentos. Analisaram-se dados de temperatura superficial, temperatura e umidade relativa do ar, coletados às 08h, 14h e 20h.Foi utilizada a técnica não paramétrica Bootstrap para as comparações das temperaturas superficiais. Os resultados apontam que os cenários arborizados apresentaram um "resfriamento" em relação as superfícies não sombreadas, indicando o papel de relevância do
