This summary is machine-generated.Urban development transforms natural landscapes, increasing impervious surfaces and causing urban heat islands (UHIs). This study links land use changes to land surface temperature (LST) at a micro-level, identifying hotspots for better urban planning.
Area Of Science
- Environmental Science
- Urban Planning
- Remote Sensing
Background
- Urban development alters landscapes, creating impervious surfaces that significantly impact urban climate through urban heat islands (UHIs).
- Understanding landscape dynamics and their effect on urban heat is crucial for sustainable city planning and thermal comfort.
Purpose Of The Study
- To evaluate urban heat islands (UHIs) in conjunction with landscape dynamics using multi-resolution remote sensing data.
- To assess the intricate spatial interrelationships between land use, land surface temperature (LST), and thermal comfort at a micro-level within heterogeneous urban environments.
Main Methods
- Utilized multi-resolution remote sensing data for land use/land cover assessment.
- Quantified urban heat island effect through spatial computation of land surface temperature (LST).
- Employed urban hotspot and Urban Thermal Field Variance Index (UTFVI) analysis to map UHI intensity.
Main Results
- Identified a strong correlation between micro-level landscape composition (pervious vs. impervious surfaces) and thermal comfort.
- Barren (C1 class) and urban (C2 class) areas were identified as predominant hotspots with elevated temperatures.
- Urban hotspot analysis revealed approximately 15.41 km² of the city experiencing very high temperatures.
Conclusions
- Micro-level land use and landscape configuration critically influence urban thermal environments and comfort.
- The study provides essential data for urban planners and policymakers to mitigate UHI effects.
- Findings support informed decision-making for sustainable urban development and improved thermal regulation.

Hybrid zones are narrow regions where two closely related species interact, mate, and produce hybrids. Relative to either parent species, hybrids may possess distinct phenotypic or genetic differences that impact their survival and reproductive success. The genetic variances introduced by hybridization influence species diversity and speciation processes within the hybrid zone.
Gene flow and natural selection are evolutionary mechanisms that shape the outcome of a hybrid zone. Gene flow...
GIS manipulation and analysis functions are vital for decision-making and planning. These activities range from data retrieval tasks, such as selecting information based on specific criteria, to advanced analytical techniques that address complex spatial problems.One critical GIS analysis method is overlaying, which combines multiple data layers to examine impacts. For example, overlaying a river-dammed lake boundary with road networks can identify affected infrastructure. Another common...
Habitat fragmentation describes the division of a more extensive, continuous habitat into smaller, discontinuous areas. Human activities such as land conversion, as well as slower geological processes leading to changes in the physical environment, are the two leading causes of habitat fragmentation. The fragmentation process typically follows the same steps: perforation, dissection, fragmentation, shrinkage, and attrition.
Perforation and dissection often occur during the initial stages of...
In the past, planning projects such as schools or public facilities required extensive manual effort to gather and compile data. Information such as property boundaries, soil characteristics, road networks, zoning regulations, and flood zones had to be sourced individually from courthouses, utility providers, and registry offices. Assembling these datasets into a coherent format often took several months, delaying project timelines.The introduction of Geographic Information Systems (GIS)...
As the construction industry moves towards more eco-friendly practices, concrete's adaptability and its ability to incorporate sustainable features make it a key material in the drive towards greener building solutions.
There are multiple approaches to achieve sustainability in a commercial concrete building. For instance, construct a concrete parking area under the building, utilizing pervious concrete paver blocks in open areas to facilitate rainwater collection through an underground...
Flood risk assessment involves careful planning and analysis to ensure the safety of communities near water retention structures. Capacity contours are a vital tool in this process, as they illustrate the potential spread of water at specific levels in a given area. In the context of building a bund across a small valley, these contours play a critical role in evaluating the safety of nearby residential areas.In this example, the bund is intended to store stormwater in the valley. The engineers...
