“…To minimize the challenges to safety and pedestrian comfort posed by strong winds, roadside green spaces with surface areas ranging from 0.7 to 1.4 can reduce wind speed in the nearby urban environment by 0.5-1.5 RTV. Therefore, wind speed should be regulated in the planning and design of the tree structure and greenery coverage of green spaces to maintain effective cooling and avoid affecting the range of pedestrian comfort [74]. Therefore, optimizing the urban wind environment involves reducing building density and height to avoid affecting urban ventilation and increasing roadside trees to ensure a comfortable commuting experience for urban residents in strong winds.…”

To prevent damage to human life and health caused by high temperatures and extreme weather and to promote sustainable urban development, it is necessary to optimize the layout of urban development elements to improve the urban wind–heat environment. Taking the high-density urban area of Shanghai as an example, this study used wavelet analysis to investigate the cyclic changes of the average annual temperature of Shanghai from 1950 to 2022 and the average annual wind speed of Shanghai from 2000 to 2020. The correlation between the urban heat environment and the urban development elements was analyzed using geographically weighted regression. The correlation was then examined using BP neural network, and finally, the impacts of different urban spatial patterns on the wind environment were analyzed using CFD numerical simulation. The results show that the average annual temperature of Shanghai city has an overall upward trend, with significant cycles of 44 and 32 years that are shortening over time. The average annual wind speed has a downward trend, with a significant main cycle of 22 years. Greening and water coverage, as well as the floor area ratio, have a significant reducing effect on surface temperature, whereas building density is positively correlated with surface temperature. Building density has a significant reducing effect on wind speed, whereas the effect of floor area ratio is not significant. The effect of building density on wind speed is significantly weakened, whereas the effect of the floor area ratio is not significant. This study provides valuable references for Shanghai and other high-density cities to optimize urban spatial patterns in order to improve the safety and comfort of the urban wind–heat environments. This study is of significant importance and value in promoting sustainable urban development, protecting the health of urban residents, and advancing spatial justice and equal well-being.

“…Thus, noise has been reported in several types of studies which relate the presence of urban green areas with mitigation of the harmful effects of noise pollution on residents and biodiversity [1][2][3][4][7][8][9][10]. According to [11], vegetation constitutes the main element of the urban landscape structure, as it directly influences the improvement of well-being and quality of life of the population.…”

“…However, information about the size, forest structure, and biophysical characteristics of these sites is still needed for planning and management of urban green areas [7]. It is known that sound can be reflected and scattered (diffracted) by plant components such as trunks, branches, and leaves; be absorbed; or destructively interfere with sound waves, mainly by ground cover [14].…”

This study aimed to evaluate the relationship between the biophysical characteristics of green areas with the reduction of noise propagation.The study was conducted in two green areas located in the city of Curitiba, Paraná, Brazil. Noise pollution levels along with the vegetation and the physical characterization were collected in each plot site of 600m2. The attenuated pollution values were defined and compared with the physical characteristics. The attenuated noise values varied from 1.7 to 14.8 dBeq. The vegetation proved to be efficient in attenuating noise pollution, showing that the site with the least amount of vegetation obtained the lowest noise attenuation values. The density and number of trees showed very strong correlations with the blocked decibel values. A combination of factors such as the shape and size of the fragments with the terrain conditions (terrain slope, and coverage) influenced the noise propagation.

“…However, despite the degradation of urban soil in general caused by soil pollution, fragmentation, mixing of soil layers, different substrates, etc., these soils can still support a wide range of urban functions [3,5,13,[17][18][19]. These urban functions primarily refer to the soil as support for the green infrastructure that represents a coherent network of open green areas in a city as the most optimal model for the development of resilient cities [20]. This suggests that the approach to urban planning and management for the purpose of preservation of the urban environment must consider altered characteristics of urban soils and the degree of their pollution [12].…”

The Impact of the Degree of Urbanization on Spatial Distribution, Sources and Levels of Heavy Metals Pollution in Urban Soils—A Case Study of the City of Belgrade (Serbia)

This study investigated the effects of urbanization on the spatial distribution, sources, and levels of heavy metals pollution in urban soils of the city of Belgrade. A total of 126 composite topsoil (0–10 cm) and subsoil (10–40 cm) samples was collected within four urban zones (central, suburban, external, and rural) of Belgrade and analysed for content, spatial distribution, sources, and pollution indices using statistical methods including descriptive statistics, correlation matrix, and Principal Component Analysis (PCA). Concentration levels of zinc (Zn), copper (Cu), cadmium (Cd), chromium (Cr), and nickel (Ni) in the soil of urban zones in Belgrade were found to be significantly higher in the central and suburban zones compared to the external and rural ones. The spatial variance and the general trend of heavy metals accumulation in the soil were found to be along the urban–rural gradient. The topsoil concentration levels for the same elements were higher compared to the subsoil concentration levels for the same elements in all urban zones, except for the external and the rural zones. These results indicate the need for the implementation of urban soils pollution monitoring according to specific urban zones to provide an applicable basis for the development of plans and strategies concerning urban soil use management for the purpose of the sustainable urban development.
