“…El crecimiento económico de una ciudad tiene una relación directa con su crecimiento urbano, por esta razón no sería posible limitar el crecimiento de una ciudad. El fenómeno de islas de calor puede intensicarse con la expansión urbana (Yang, Chen, Qian, Wu, Zheng y Huang, 2019), por lo que es necesario prestar atención a la planeación urbana desde este contexto. Actualmente las investigaciones se están centrando en el tipo de material que debe ser usado en cubiertas (Shi et al 2019;Ulpiani, di Perna y Zinzi, 2019;Zinzi, Carnielo y Mattoni, 2018), con el objetivo de mitigar los efectos del cambio climático, ahorrar energía y mejorar la calidad del aire.…”

Crecimiento urbano e impermeabilización del suelo alrededor de la Reserva Forestal Thomas van der Hammen, en la ciudad de Bogotá

Bogotá ha tenido una rápida urbanización en las últimas décadas, caracterizada por la falta de planeación, la contaminación de cuencas y la generación de impactos ambientales. La reserva Thomas van der Hammen no ha sido ajena a estos procesos de urbanización. Sin embargo, esta área, ubicada al noroccidente de la ciudad, tiene una gran relevancia ambiental, pues es un corredor ecológico que conecta a los cerros orientales con el río Bogotá. En este trabajo se realiza un estudio multitemporal alrededor de la reserva usando técnicas de teledetección. Usando índices espectrales, como el IBI, y calculando la temperatura de superficie, se logró discriminar las áreas impermeabilizadas en el periodo comprendido entre el año 1989 y el 2018. Los resultados demuestran que las técnicas de teledetección para monitorear áreas impermeables son confiables, de manera que se pueden medir las intervenciones antrópicas en el tiempo. El monitoreo realizado sobre la reserva muestra que esta ha evitado que la urbanización en el norte de la ciudad haya conectado con el río Bogotá y generara una carga mayor para la cuenca al impermeabilizar esa zona de la ciudad.

“…To quantitatively evaluate the coupling relationships between ISFWCs and LSTWCs in the spatial extent, the coupling indicators are utilized in this study [41]. The coupling indicators are capable to measure the spatial distance of ISFWCs and LSTWCs and the azimuths of the moving trajectories of ISFWCs and LSTWCs, respectively.…”

“…Keeping in mind the importance of providing implications for steering urban expansion and intensification from the standpoint of LST and IS correlations at multiple scales either spatially or temporally, this study (1) generates typical summertime-scale LST patterns considering temporal variations of LST using non-parametric Multi-Task Gaussian Process (MTGP) model [32]; (2) quantifies the relationships between LST and IS by integrating moving trajectories and multiple indicators (e.g., spatial coupling indicators [41] and impervious surfaces contribution index (ISCI) [42]) at both the city scale and sub-region scale. The typical summer time LST maps maintain the global diversity and local variation of LST patterns instead of investigating LST and UHI in a static perspective [32,33].…”

“…The MTGP model are utilized to generate typical LST patterns in summer days [32]. The analyses in this study has been divided into two parts: (1) at the city scale, characterizing the spatiotemporal variations of LST and IS patterns using weighted center [16,39], moving trajectories [16,39] and spatial coupling indicators [41]; (2) at the sub-region scale, quantifying the coupling relationships of LST and IS in eight cardinal directions using ISCI [42], urban heat island ratio index (URI) [40] and sprawl rate [34,42].…”

Conspicuous expansion and intensification of impervious surfaces accompanied by rapid urbanization are widely recognized to have exerted evident impacts on the urban thermal environment. Investigating the spatially and temporally varying relationships between Land Surface Temperature (LST) and impervious surfaces (IS) at multiple scales is of great significance for steering IS expansion and intensification. This study proposes an analytical framework to investigate the spatiotemporal variations of LST and its responses to IS in Wuhan, China at both city scale and sub-region scale. The summer LST patterns in 2002–2017 are extracted by Multi-Task Gaussian Process (MTGP) model from raw 8-day synthesized MODerate-resolution Imaging Spectroradiometer (MODIS) LST data. At the city scale, the weighted center of LST (LSTWC) and impervious surface fraction (ISFWC), multi-temporal trajectories and coupling indicators are utilized to comprehensively examine the spatial and temporal dynamics of LST and IS within Wuhan. At the sub-region scale, urban heat island ratio index (URI), impervious surfaces contribution index (ISCI) and sprawl rate are introduced for further quantifying the relationships of LST and IS. The results reveal that IS and hot thermal landscapes expanded by 407.43 km2 and 255.82 km2 in Wuhan in 2002–2017 at city scale. The trajectories of LSTWCs and ISFWCs are visually coherent and both heading to southeast direction in general. At the sub-region scale, the specific cardinal directions with the highest ISCI variations are examined to be the exact directions of ISFWC trajectories in 2002–2017. The results reveal that the spatiotemporal variations of LST and IS are highly correlated at both city and sub-region scales within Wuhan, thus testifying the significance of steering IS expansion and renewal for controlling urban thermal environment deterioration.

The suitability of urban construction land (SUCL) is key to the appropriate utilization of land resources and represents an important foundation for regional exploration and land management. This study explores the SUCL conceptual framework by considering the theory of human-land relationships. The upper reaches of the Yangtze River were studied, a typical ecologically-sensitive area of China. The spatial pattern and control of the SUCL were determined using the improved entropy method. The results show that an area of 91 × 104 km2 was categorized as prohibited or restricted, and these categories account for 28.61% and 50.66% of the total area, respectively. Priority areas and suitable areas are mainly located in the Chengdu Plain, the urban agglomeration of southern Sichuan Province, Chongqing, and the economic corridor in the west, and the surrounding cities of Guiyang and Kunming. SUCL hotspots feature obvious spatial heterogeneity and are concentrated in Sichuan Basin and Guizhou Plateau. The SUCL is obviously constrained by the physical geography of this region. In addition, towns affected by the pole–axis effect have stronger suitability for development and construction. These findings will be very useful for land managers as they provide relevant information about urban development in mountainous areas.
