Study of Urban Heat Island Effect in Hangzhou Metropolitan Area Based on SW-TES Algorithm and Image Dichotomous Model

SAGE Open, Год журнала: 2023, Номер 13(4)

Опубликована: Окт. 1, 2023

In recent years, with economic development, urbanization has been accelerating. the past 100 global average temperature increased by 0.5°C, and according to predictions of most climate models, will continue increase 1.5°C 3.0°C in next years. Under influence warming, urban heat island effect problem is becoming more serious, bringing much harm. Studying thermal its influencing factors great significance for sustainable development. this study, seasonal interannual surface changes study area are inverted based on SW-TES algorithm, LST inversion algorithm simply verified. At same time, a cell dichotomous model was established explore different land use types normalized vegetation indices Hangzhou metropolitan analyzed. The results showed that overall heating trend trend, expansion rate regional construction relatively fast, scale increasing. Based areas types, we obtained trends each type [from 2005 2018] found there negative correlation between index. This provides theoretical basis evaluate analyze impact it would promote

XGBoost-Based Analysis of the Relationship Between Urban 2-D/3-D Morphology and Seasonal Gradient Land Surface Temperature

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, Год журнала: 2024, Номер 17, С. 4109 - 4124

The escalation of greenhouse gas emissions has led to a continuous rise in land surface temperature (LST). Studies have highlighted the substantial influence urban morphology on LST; however, impact different dimensional indicators and their gradient effects remain unexplored. Selecting area Shenyang as case, we chose various representing dimensions. By employing XGBoost for regression analysis, aimed explore 2D 3D seasonal LST its effect. following results were obtained: (1) spatial pattern spring winter was higher suburbs than center. (2) correlation patterns similar, except proportion woodland grass (PWG), digital elevation model (DEM), sky view factor (SVF), which exhibited opposing trends summer autumn. (3) Vegetation construction had highest index, followed by building forms natural landscapes morphology. (4) each indicator varied significantly across gradients. Among all indicators, landscape social development, forms, skyscape impacts areas. built-up areas greater suburban findings this study can assist adjusting provide valuable recommendations targeted improvements thermal environments, thereby contributing sustainable development.

A review on BIPV-induced temperature effects on urban heat islands

Urban Climate, Год журнала: 2023, Номер 50, С. 101592 - 101592

Urban Heat Islands (UHI) occur in and around cities, leading to warmer temperatures than surrounding rural areas. The UHI effect increases energy demand, air pollution levels, heat-related illness mortality. Solar is one of the most widely adopted renewable generation technologies built environment. photovoltaic (PV) systems, integrated into building envelopes, can form a cohesive design, construction solution for buildings, namely, building-integrated system (BIPV). However, BIPV panels might potentially exacerbate intensity by trapping more heat urban This review paper uses detailed literature survey over 100 sources evaluate whether uptake systems areas contributes an aggravation effect. found both direct indirect impacts on UHI, which also identified fundamental causes such as albedo dispersion how this would be embodied installations. Furthermore, discusses mitigate impact well future research directions concern relation design.

Global warming has led to a surge in heat health risks (HHRs), the impacts of which are particularly pronounced metropolitan areas developing countries. In current study, six - Beijing, China; Cairo, Egypt; Jakarta, Indonesia; Mumbai, India; Rio de Janeiro, Brazil; and Tehran, Iran were selected as study area further differentiate built-up landscapes by utilizing concept local climate zones. Moreover, we assessed similarities differences HHR associated with landscape. Results revealed 30.67% higher compact than open type. Urban green spaces played an effective but differentiated role mitigating HHR. That is, low vegetation urbanized trees suburban significantly mitigated Collectively, our findings emphasize planning management addressing provide empirical support for implementing mitigation adaptation strategies.
