Accessing the Heat Exposure Risk in Beijing–Tianjin–Hebei Region Based on Heat Island Footprint Analysis

Atmosphere, Journal Year: 2022, Volume and Issue: 13(5), P. 739 - 739

Published: May 5, 2022

The urbanization process leads to the enhancement of urban heat island (UHI) effect, and high temperature brought by it exacerbates risk exposure seriously endangers human health. Analyzing spatiotemporal characteristics levels is important for formulating prevention control measures. Therefore, this study analyzes based on UHI footprint (FP) explores relationship between factors in Beijing–Tianjin–Hebei (BTH) region from 2000 2020, obtains following conclusions: (1) BTH suffers severe problems, with FP ranging 6.05 km (Chengde) 32.51 (Beijing), majority cities show significant trends increase. (2) With increase FP, massive populations are exposed within areas, average annual population at across 269,826 166,020,390 a predominance people (more than 65% total) generally showing increasing trends. (3) significantly correlated factors, indicating that an reason level. These results suggest continuous process, problem faced will persist gradually worsen, which must be paid attention effective mitigation measures taken.

Impact of environmental comfort on urban vitality in small and medium-sized cities: A case study of Wuxi County in Chongqing, China

Frontiers in Public Health, Journal Year: 2023, Volume and Issue: 11

Published: Feb. 6, 2023

China's urbanization has exceeded 64% and a large number of small medium-sized cities are the key development areas in new stage. In urban planning, it is very important to reveal influence environmental comfort on vitality improve life quality residents these towns. Thus, study investigated impact using ordinary least squares regression Wuxi County. Environmental was assessed through comprehensive analysis built-up area represented by intensity. addition, pathways were identified model validation verified. The conclusions as follows: (1) distributed spatially similarly, both gradually decline from center periphery. It high east low west, south north. (2) Population density, POI mixing degree, building road network density have significant positive effects vitality. greatest Building height, age, river buffer negative (3) positive, terms time, order afternoon > morning evening. Finally, method for assessing constructed, promoting effect improvements These findings will fill gap between physical space social needs planning practices provide reference cities.

Coupling relationships between urban block spatial morphology and microclimate in severe cold regions

iScience, Journal Year: 2023, Volume and Issue: 26(11), P. 108313 - 108313

Published: Oct. 23, 2023

This study investigates the relationship between urban block spatial morphology and microclimate in severe cold regions, using Shenyang, China as a case study. We employed computational fluid dynamics theory-based numerical simulation software controlled variable approach to analyze effects of four key aspects: street conforming line ratio, interface density, aspect building roof forms. The primary findings are follows: Decreasing ratios initially increase average wind speed temperature. Lower densities reduce but raise Higher correspond increased decreased Additionally, upward sloping roofs correlate with higher research provides perspective for evaluating microclimates, considering human perception space. It also suggests layout design strategies different types streets climate environment.

A conceptual framework to mitigate the adverse effects of surface urban heat islands through urban acupuncture: a two-phase scenario of diagnosis and prescription at the neighborhood scale

Frontiers in Environmental Science, Journal Year: 2024, Volume and Issue: 12

Published: Jan. 29, 2024

Rising temperatures, a major global environmental challenge, negatively impact health, the environment, society, and economy. Surface Urban Heat Islands (SUHI), exacerbated by urbanization climate change, intensify vulnerabilities for urban areas residents. planning design aime to reduce these through large-scale small-scale interventions. However, addressing significance of capillary effects resulting from interventions bottom-up community engagement is important. acupuncture (UA) an emerging approach in contemporary that focuses on mitigate SUHIs at level. This study develops framework mitigating impacts UA implementation design. The proposed consists two key phases: diagnosis prescription. During phase, we analyzed heat-vulnerable points identify indicators contributing development exacerbation SUHIs. Then, employed Matrix Cross Impact Multiplications Applied Classification (MICMAC) technique comprehensively assess 75 influential related structure across various aspects scales, focusing mesoscale. Among them, 30 leading were identified, which morphological emerged as significant catalysts. Moving prescription developed UA-based called “5 Wh Question” addresses five fundamental questions: why, who, what, how, where. Our findings can provide comprehensive solutions policymakers planners address identified points.
