The appropriate design of urban ventilation corridors (VCs) can improve the thermal environment, thereby reducing energy consumption and promoting sustainable development. However, existing research lacks a comprehensive grasp characteristics VCs from multiple dimensions quantitative analysis its cooling effect. We propose novel approach based on data mining to comprehensively consider morphological environmental explore correlation between VC Selecting Nanjing as an example, index system was constructed, effect investigated, optimal range with different underlying surface types obtained. Results revealed that is closely related surface, leading temperature difference up 5.4 °C. vary 13 600 m. recommended parameter intervals for were determined. Finally, targeted strategies alleviate heat island proposed types. study output contributes VCs, which great significance in alleviating development cities.

Contribution of urban trees in reducing land surface temperature: Evidence from china's major cities

International Journal of Applied Earth Observation and Geoinformation, Journal Year: 2023, Volume and Issue: 125, P. 103570 - 103570

Urban trees mitigate urban heat by altering evapotranspiration processes and providing shade to their surrounding environment. Nevertheless, the impact through which three-dimensional tree characteristics alleviate Land Surface Temperature (LST) remain uncertain, especially for climatic zone differences. In this study, we investigated potential of LST in 35 Chinese major cities quantified importance diverse factors influencing magnitude cooling effects. Results showed that tree-covered areas was about 2.23 °C lower than built-up during summer, but an opposite temperature pattern observed winter these are mostly distributed Bs (arid-steppe) Dw (cold-dry winter) climate zones. Moreover, found every 1 m increase height, decreased ∼ 0.19 0.10 summer winter, respectively. Notably, also seasonal differences drivers intensity, with digital elevation model (DEM = ∼13.21 %) as key factor. These findings can help planners architects better understand effects cooling, be a significant guide reducing heat.

An investigation on the impact of blue and green spatial pattern alterations on the urban thermal environment: A case study of Shanghai

Ecological Indicators, Journal Year: 2023, Volume and Issue: 158, P. 111244 - 111244

Consistent urbanization and global warming escalates the summer temperatures of urban, significantly impacting daily lives endangering well-being. It is difficult to balance urban construction increasing blue-green space. Hence, understanding impact changes in spatial patterns different spaces on thermal environment beneficial rational layout patterns. Drawing from case study Shanghai, by employing bivariate autocorrelation multiscale geographically weighted regression, interplay between distribution modifications land surface temperature grades scrutinized, thus unraveling underlying mechanisms their mutual influence. The findings reveal following: (1) transformation pattern exhibited substantial discrepancies northern southern sectors. (2) alteration Shanghai varies spatially characterized a decrease grade southwestern suburbs, an increase east, almost no change central region. (3) Furthermore, correlation extent manifested unevenness. (4) Finally, mechanism alterations city emanates primarily influence heat exchange areas. instability can provide implications for planners.
