“…These influences, aka UHI sensitivities to "fine-grained" urban landscapes, are not well understood and a wide range of disparities exist. For example, in summer, a 10% increase in greenspace would result in a decrease of 3.4 o C in LST in Phoenix, Arizona (Connors et al, 2012), but only 2°C in Manchester, UK (Skelhorn et al, 2014), and 1.1 o C in Delhi, India (Pramanik and Punia, 2019). Similarly, every 10% increase in the built-up proportion would increase LST by 3.2 °C in Phoenix, Arizona (Connors et al, 2012), but only by 0.45 °C in the Baltimore-DC metropolitan area (Tang et al, 2017).…”

“…We found that, on average, the temperature tends to increase by approximately 0.8 • C for every 1 km increase in distance. Huang et al [56] reported a 0.4 • C/km air temperature reduction in Nanjing, China; also, a surface temperature drop of 0.15 • C/km in Beijing, China [42] and 3.89 • C/km in Delhi, India [57] has been observed. Different values of temperature reduction gradient might be related to using different measuring methods, climate background and the category of temperature [58].…”

The cooling effect of green spaces as an ecological solution to mitigate urban climate change is well documented. However, the factors influencing the microclimate in the built environment around forest parks, diurnal variations of their impact and their degree of importance have not been explicitly addressed. We attempted to quantify how much various landscape parameters, including land cover and spatial location, impact the ambient air and surface temperature in the area around Beijing’s Olympic Forest Park. Data were taken along strategically located traverses inside and outside the park. We found: (1) The air temperature during the day was 1.0–3.5 °C lower in the park than in the surrounding area; the surface temperature was 1.7–4.8 °C lower; air humidity in the park increased by 8.7–15.1%; and the human comfort index reduced to 1.8–6.9, all generating a more comfortable thermal environment in the park than in the surrounding area. (2) The distance to the park and the green space ratio of the park’s surrounding area are significant factors for regulating its microclimate. A 1 km increase in distance to the park caused the temperature to increase by 0.83 °C; when the green space ratio increased by 10%, the temperature dropped by 0.16 °C on average. The impact of these two parameters was more obvious in the afternoon than in the middle of the day or in the morning. The green space ratio could be used for designing a more stable thermal environment. (3) Land cover affects surface temperature more than it does air temperature. Our data suggest that an urban plan with an even distribution of green space would provide the greatest thermal comfort.

“…The effect of land cover (vegetation cover, green spaces, and trees) on UHI mitigation varies depending on the amount, spatial configuration, evapotranspiration, and adaptive capacity of the planting. Although the amount of green space is a key factor in reducing regional temperatures [ 41 , 80 , 81 , 82 ], the structure and configuration of green space also influence surface temperatures greatly [ 76 , 83 , 84 , 85 , 86 , 87 ]. This entails the structure of green space, including its size, shape, and composition [ 53 , 76 , 88 , 89 ]; the shape of green space in urban areas [ 90 , 91 ]; and the density of green space in an area [ 46 ].…”

With the global acceleration of urbanization, temperatures in cities are rising continuously with global climate change, creating an imminent risk of urban heat islands and urban heating. Although much research has attempted to analyze urban heating from various perspectives, a comprehensive approach to urban planning that addresses the problem is just beginning. This study suggests a conceptual framework for multidisciplinary understanding of urban heating by reviewing 147 selected articles from various fields, published between 2007 and 2021, that discuss urban heating mitigation. From these, we identified several outdoor and indoor temperature-reduction factors and proposed area-based, zoning-based, and point-based approaches to mitigate urban heating.
