Urban growth and development has significantly affected urban heat island (UHI) due to urbanization. Particularly in the cities developing countries, assessment of UHI emerged as one core research themes it affects ecological environment livability cities. Thus, is crucial for climate mitigation sustainable landscape planning. This study identifies dynamics patterns impact composition configuration on thermal English Bazar Agglomeration (EBUA), Eastern India, along urban–rural gradient (URG) approach. Geospatial approaches spatial metrics were employed assess pattern environment. Descriptive inferential statistics have also been used find effects The result validated based location correlation analysis. built-up area increased by about 63.54%; vegetation covers water bodies declined 56.72% 67.99% from 2001 2021.

Simulation of Cooling Island Effect in Blue-Green Space Based on Multi-Scale Coupling Model

Remote Sensing, Journal Year: 2023, Volume and Issue: 15(8), P. 2093 - 2093

Published: April 16, 2023

The mitigation of the urban heat island effect is increasingly imperative in light climate change. Blue–green space, integrating water bodies and green spaces, has been demonstrated to be an effective strategy for reducing enhancing environment. However, there a lack coupled analysis on cooling blue–green space at meso-micro scale, with previous studies predominantly focusing effect. This study single canopy model (UCM) mesoscale Weather Research Forecasting (WRF) numerical simulate Eastern Sea-River-Stream-Lake Linkage Zone (ESLZ) within northern subtropical zone. In particular, we comparatively investigated micro-scale via three strategies increasing vegetation, bodies, coupling using temperature data block scale 100 m square center hottest day summer.

Measuring urban thermal environment from accessibility-based perspective: A case study in a populous city

Geography and sustainability, Journal Year: 2024, Volume and Issue: 5(3), P. 329 - 342

Published: Feb. 20, 2024

Understanding the spatial interaction among residents, cooling service, and heat risk area in complex urban areas is conducive to developing targeted management. However, traditional thermal environment assessments typically relied on simply linear integration of associated indicators, often neglecting effect. To explore three elements, this study proposes an accessibility-based assessment framework. Using Zhengzhou, a rapidly urbanizing city, as example, remotely sensed images from periods (2010, 2015 2020) were applied extract green space (UGS) hot island (HIA). An improved two-step floating catchment (2SFCA) method bivariate local Moran' I employed whether residents clustering locations are more likely access service or be exposed risk. The results demonstrate that UGS city has been expanding, whereas HIA shrank within inner then increased 2020. Even though may last decade, could exacerbated. Spatial autocorrelation shows increase disadvantageous for resident congregation. when sufficient services provided, these still high developed framework provides novel insight into residents' exposure accessibility, findings assist planners targeting improvement extra locations.
