Cooling Effect of Trees with Different Attributes and Layouts on the Surface Heat Island of Urban Street Canyons in Summer

Atmosphere, Год журнала: 2023, Номер 14(5), С. 857 - 857

Опубликована: Май 11, 2023

In recent years, the impact of surface heat islands in urban street canyons has become increasingly apparent. However, research on use trees to mitigate remains limited. To address this gap, study combines experiments and simulations analyze cooling effect temperatures under varying timeframes layouts an east–west canyon. The results reveal that temperature road decreases by 10–15 °C, which is 2–4 times greater than south side. Moreover, at 5:00 p.m. afternoon, side 10.3 twice north practical planning design, diameter tree canopy should be maximized, with leaf-area densities 1.5 m2/m3 selected. Additionally, layout optimized maximize coverage. These findings have important implications for optimizing plant selection placement canyons.

Impacts of spatial explanatory variables on surface urban heat island intensity between urban and suburban regions in China

International Journal of Digital Earth, Год журнала: 2024, Номер 17(1)

Опубликована: Янв. 16, 2024

The intensified thermal environment in suburban areas is raising wide concerns for human society and public health due to rapid urbanization. Although the satellite-derived surface urban heat island intensity (SUHII) a commonly used indicator, it still needs be determined SUHII between challenges delineating their boundaries with changes. Thus, comprehensive analysis of spatial explanatory variables (SEVs) among highly needed. Here, using long-term satellite observations, we analyzed spatiotemporal patterns different temporal intervals (i.e. seasonal diurnal) contribution SEVs areas. Our results indicate that shows predominantly increasing trend from 2012–2021 cities China. Despite trends increasing/decreasing) being relatively consistent both suburban, latter higher proportion regarding various SEVs. Besides, partial least squares regression (PLSR) model major contributors are landscape shape index (LSI), patch density (PD), digital elevation (DEM), while areas, those critical LSI, normalized difference built-up (NDBI), DEM. These findings can facilitate sustainable design planning nature-based solution.

Study on Mechanism of Visual Comfort Perception in Urban 3D Landscape

Buildings, Год журнала: 2025, Номер 15(4), С. 628 - 628

Опубликована: Фев. 18, 2025

Landscape visual evaluation is a key method for assessing the value of landscape resources. This study aims to enhance environment and sensory quality urban landscapes by establishing standards comfort natural landscapes. Using line-of-sight multi-factor analysis algorithms, assesses spatial visibility exposure building clusters in core areas Harbin, identifying viewpoints with high potential. Focusing on landmark 3D models surrounding landscape’s environment, uses city’s sky, greenery, water features as elements evaluating By integrating GIS data, big data street-view photos, image semantic recognition, algorithms extract both objective subjective values at observation points, followed mathematical modeling quantitative analysis. The explores coupling relationship between physical perceived visibility. results show that effectively reveals buildings landscapes, providing scientific support planning contributing development more distinctive attractive space.
