“…This provides new perspectives and solutions for the heat island phenomenon and environmental challenges faced by cities at different development levels around the world. This paper focuses on the mitigation of the UHI effect in Yan'an City by the studied forest, which has been applied in Shanghai and Zhengzhou, China and Medan, Indonesia [50][51][52].…”

In this study, MODIS land products and China land cover datasets were used to extract normalized difference vegetation index, land surface temperature, and vegetation cover type in Yan’an City during the summers of 2017–2022. On this basis, analysis of spatial change and correlation were carried out as a way to study the mitigation effect on urban heat islands in Yan’an City with forest. The study showed that: (1) The coverage of normalized difference vegetation index over 0.4 in summer in Yan’an City increased from 59.38% to 69.12%, and the vegetation showed good growth conditions. It has a spatial distribution pattern of more in the south and less in the north. (2) The proportion of the urban heat island in Yan’an City increased from 15.51% to 16.86%. Urban heat island intensity fluctuated year by year, with the maximum urban heat island intensity of 6.26 °C appearing in 2019. It has a spatial distribution pattern of less in the south and less in the north. The transition rate of temperature field grade from low to high is 73.32%, and the transition rate to low is only 0.31%. (3) There is a negative correlation between land surface temperature and normalized difference vegetation index in Yan’an City. Vegetation has a mitigating effect on the UHI and the best cooling effect among the vegetation is shown by forest. The cooling effect of forest in Yan’an City is attenuated by an increase in distance, and the effective range is greater than 1000 m. In this study, the regulation effect of forest on the urban heat island was obtained by digging deeper into the intrinsic connection between spatial change in vegetation cover and land surface temperature change in Yan’an City. It provides an important reference for the formulation of meteorological protection policy as well as the promotion of sustainable development of the urban ecological environment and is of guiding significance for future urban planning and ecological construction.

“…While urbanization has accelerated the conversion of vegetated land covers to built-up areas, the effects of green vegetation as biofilters for particulate matter have been reduced ( Lee et al, 2022 ), urban green and blue spaces being inversely associated with pandemic COVID-19 incidence and mortality ( Peng et al, 2022 ; Ciupa, 2023 ; Falco et al, 2023 ). Also, as a consequence, the urban land surface temperature increased ( Zaitunah et al, 2022 ) in annual mean at the rate of 3.0 °C/century during the 1901–2015 period ( Matsumoto et al, 2017 ).…”

“…The storage heat flux exceeds the sensible heat flux in urban areas, whereas the sensible heat flux is higher than storage heat flux in industrial areas. In particular, negative storage heat flux appears at a number of industrial points 26,27 . This tendency shows that high surface temperature in the periurban industrial areas of Bucharest is induced by mass energy consumption, because most of the anthropogenic heat discharge is transferred to the atmosphere as sensible heat.…”

Spatial change in the urban landscape related to land cover conversion due to urbanization is recognized as the critical factor affecting the formation and intensity of Urban Heat Island (UHI), which under summer Heat Waves (HWs) substantially modifies the land surface-aerodynamic properties, the energy and water balances and urban thermal environment. One of the most important goals of satellite-based urban thermal environment investigations is the better understanding of the physical content of different satellite-derived biophysical parameters. The specific object of this study is to use time-series Landsat TM/ETM + and MODIS Terra/Aqua satellite data for assessing of urban land cover-air and land surface temperature interactions during period between 2000 and 2022 years over Bucharest metropolitan area. The air (TA) and land surface temperature (LST), key parameters in urban climate research are analyzed in relation with land surface albedo and Normalized Difference Vegetation Index (NDVI) variables, and quantified the spatiotemporal cooling effects of urban green landscape characteristics impacts on urban thermal environment dynamic at city level. The rank correlation analyses revealed that, at the pixel-scale, during summer season (June-August) TA and LST presents a strong positive correlation (r= 0.86%, p<0.01). During summer periods (June -August), LST-NDVI shows a negative correlation (for central city areal r= -0.23, p< 0.05; and for metropolis areal r= -0.67, p<0.01). Also, the monthly mean UHI intensity belongs to the range of (1.3 o C to 6.5 o C), and the most intense UHI occurs during the day-time in the summer season in synergy with heat waves periods. Several urban/periurban zones and landscapes bring diurnally and seasonally different contributions to the local and regional thermal environment.
