“…It is difficult to quantify vegetation at the urban scale, which leads to the difficulty of vegetation modeling. In small and medium-scale studies, the method of LiDAR can be combined to assist in the modeling of vegetation [59]. Therefore, the consideration of vegetation roughness can be added to the calculation of FAI.…”

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

“…Owing to its efficacy in the cost-effective gathering of large-scale data, Light Detection and Ranging (LiDAR) technology has emerged as a crucial tool for articulating the three-dimensional architecture of urban landscapes [26]. The DEM offers a comprehensive depiction of terrain characteristics, encapsulating not only the footprints of buildings but also additional vertical elements such as building heights, vegetation, and surface elevations [26,39,40]. Another advantage of the DEM-measured building height is its proficiency in discerning height variations in complex urban areas [26].…”

Wind, a renewable resource with growing importance in the contemporary world, is considered a capable tool for addressing some of the problems linked with rapid urbanization, unsustainable development, and climate change. As such, understanding modelling approaches to wind characteristics in cities becomes crucial. While prior reviews delve into the advancements in reduced-scale models and computational fluid dynamics simulations, there is scant literature evaluating large-scale spatial modelling of urban wind environments. This paper aims to consolidate the understanding of spatial modelling approaches to wind characteristics in cities by conducting a systematic literature review with the PRISMA protocol to capture the contributions to sustainable urban development. The reviewed articles are categorized under two distinctive approaches: (a) studies adopting the wind morphometric approach, encompassing theoretical foundations, input factors, and computation methods and (b) studies adopting the urban climate mapping approach, centering on the amalgamation of wind with urban microclimate analysis. The findings suggest that wind morphometric methodologies hold considerable promise due to their straightforward calculations and interpretability. Nonetheless, issues related to data precision and accuracy challenge the validity of these models. This review also probes into the implications of these two distinctive approaches for urban planning and policymaking, advocating for more sustainable urban development.
