“…Significant spatial heterogeneity in the Landscape-LST relationship is observed in different types of UFZs due to the impact of socioeconomic activities and related landscape characters. Diversified socioeconomic activities resulted in different anthropogenic heat, which has an important impact on urban LST [ 63 ]. In terms of anthropogenic heat, population density, traffic flow, industrial energy consumption, and building energy consumption are the most important components [ 64 , 65 ].…”

Local warming induced by rapid urbanization has been threatening residents’ health, raising significant concerns among urban planners. Local climate zone (LCZ), a widely accepted approach to reclassify the urban area, which is helpful to propose planning strategies for mitigating local warming, has been well documented in recent years. Based on the LCZ framework, many scholars have carried out diversified extensions in urban zoning research in recent years, in which urban functional zone (UFZ) is a typical perspective because it directly takes into account the impacts of human activities. UFZs, widely used in urban planning and management, were chosen as the basic unit of this study to explore the spatial heterogeneity in the relationship between landscape composition, urban morphology, urban functions, and land surface temperature (LST). Global regression including ordinary least square regression (OLS) and random forest regression (RF) were used to model the landscape-LST correlations to screen indicators to participate in following spatial regression. The spatial regression including semi-parametric geographically weighted regression (SGWR) and multiscale geographically weighted regression (MGWR) were applied to investigate the spatial heterogeneity in landscape-LST among different types of UFZ and within each UFZ. Urban two-dimensional (2D) morphology indicators including building density (BD); three-dimensional (3D) morphology indicators including building height (BH), building volume density (BVD), and sky view factor (SVF); and other indicators including albedo and normalized difference vegetation index (NDVI) and impervious surface fraction (ISF) were used as potential landscape drivers for LST. The results show significant spatial heterogeneity in the Landscape-LST relationship across UFZs, but the spatial heterogeneity is not obvious within specific UFZs. The significant impact of urban morphology on LST was observed in six types of UFZs representing urban built up areas including Residential (R), Urban village (UV), Administration and Public Services (APS), Commercial and Business Facilities (CBF), Industrial and Manufacturing (IM), and Logistics and Warehouse (LW). Specifically, a significant correlation between urban 3D morphology indicators and LST in CBF was discovered. Based on the results, we propose different planning strategies to settle the local warming problems for each UFZ. In general, this research reveals UFZs to be an appropriate operational scale for analyzing LST on an urban scale.

“…In the future research, it is necessary to consider how to calibrate the NTL data which is got by different sensors of different institutions in different period to the same brightness reference to extract the city built-up area and extend the time series that is studied in this paper. Furthermore, our future study will consider to use the methods proposed in the newest literature [ 42 , 43 ].…”

As the capital and one of the metropolises in China, Beijing has met with a number of serious so-called "urban diseases" in the process of rapid urbanization such as blind expansion of urban areas, explosion of population and the increase of urban heat island effect. To treat these “urban diseases” and make the metropolis develop healthful and sustainable in Beijing in the future, the spatial characteristics of metropolis developments in Beijing are explored in this paper. The urban built-up areas in Beijing are extracted using the DMSP-OLS nighttime light data from 1992 to 2013. The characteristics of the urban developments of Beijing are studied, including spatial and temporal scales of urban developments, urban barycenter of Beijing and its transfer trajectory, variations of urban spatial forms and the differences of urban internal developments. The results have shown that the built-up areas had been increasing and circling extending from the central urban areas to the outer spaces in the last 21 years. The built-up area had expanded by 878km2 in 1992–2013, and the built-up area in 2013 had expanded to three times comparing to that of 1992. The expanding area of the built-up area in the northeast is the largest. The expansion of the urban had mainly occurred in 1996–2007, and the expanded area had accounted for 92% of the total research period. During the whole research period, the urban barycenter of Beijing had moved 5000.71 meters towards Northeast 28° of its original place from Dongcheng District to Chaoyang District. The development level of each municipal district had been increasing year by year, and the development differences among the municipal districts had been gradually reduced; the spatial forms of Beijing had been alternately changed between extensive and intensive expansion. The results of this study can help to plan urban land use and people migration of Beijing.

“…60-68 -ISSN: 2520 La rápida urbanización ha provocado cambios radicales en el clima urbano. Como resultado, los problemas relacionados con los entornos térmicos urbanos se han vuelto más prominentes (Yang, et al, 2020). La conducta de las personas con respecto al mal manejo de los suelos tiene resultados perjudiciales sobre este recurso, originando cambios climáticos, perturbaciones y peligros que están impactando a los geoecosistemas de los territorios mediterráneos áridos, semiáridos y subhúmedos secos (Lorenzo Monterrubio, et al, 2018), generando zonas de transición abrupta ambientes silvestres y matriz antrópica originando mayores riesgos de propagación de agentes patógenos, presentando una alta diversidad ya que son interfaces usadas por especies de diferentes tipos de ambientes con potencial para una mayor diversidad viral que actúan como vector de virus entre zonas silvestres y antrópicas y viceversa (Olival, et al, 2017).…”

El presente documento tiene como objetivo proponer la implementación de una cultura urbana en tiempos de COVID 19 para evitar su propagación, se logró a través de una revisión literaria de 18 artículos indexados y 12 sitios web, los artículos indexados están distribuidos de la siguiente forma: 10 en Scopus, 6 en Scielo, y 2 en latindex. A través de la revisión literaria se expone 3 culturas que la sociedad debe de tener en cuenta, las cuales son: 1) La cultura de respeto a las normas como estrategia para acatar normativas de aislamiento social en tiempos de emergencia sanitaria, 2) La cultura ambiental como estrategia para evitar propagación de la pandemia y 3) La cultura de paz como estrategia para solucionar conflictos sociales en tiempos de emergencia sanitaria. Estas estrategias serían de gran ayuda al implementarlas en los planes curriculares de todos los grados de educación ya sea formal y no formal, para concientizar a la sociedad a respetar las normas que aprueban los gobiernos nacionales, regionales y locales, respetando los derechos humanos y medio ambiente para no alterar los ecosistemas evitando mayores riesgos de propagación de agentes patógenos que originaría una nueva pandemia, guerras y destrucción.
