Urban green spaces have long been cherished as the "lungs of city", it can not only improve air quality and enhance residents' health. The impact urban on pollution health has attracted great attention. In this paper, we select 31 provinces in China research samples use ArcGIS software to draw spatial distribution maps spaces, pollution, China, characterizing their spatiotemporal changes order explore whether there is a correlation among three. On basis, paper utilizes panel data Chinese provincial-level from 2010 2020 conducts empirical tests through two-way fixed effect model threshold regression model. findings are follows: (1) bring environmental benefits, but also benefits greater than benefits. (2) There risk northern significant. Conversely, no southern (3) Although regulations role enhancing may be further weakened economy develops.

Spatiotemporal Dynamics of PM2.5-Related Premature Deaths and the Role of Greening Improvement in Sustainable Urban Health Governance

Atmosphere, Journal Year: 2025, Volume and Issue: 16(2), P. 232 - 232

Environmental particulate pollution is a major global environmental health risk factor, which associated with numerous adverse outcomes, negatively impacting public in many countries, including China. Despite the implementation of strict air quality management policies China and significant reduction PM2.5 concentrations recent years, burden caused by has not decreased as expected. Therefore, comprehensive analysis necessary for more effective management. This study makes an innovative contribution integrating Enhanced Vegetation Index (EVI), Normalized Difference (NDVI), Soil-Adjusted (SAVI), providing framework to assess impacts green space coverage, promoting healthy urban environments sustainable development. Using Nanjing, China, case study, we constructed impact assessment system based on quantitatively analyzed spatiotemporal evolution premature deaths from 2000 2020. Multiscale Geographically Weighted Regression (MGWR), explored greening improvement attributed proposed relevant governance strategies. The results showed that (1) Nanjing could be divided into two stages: 2000–2015 2015–2020. During second stage, due respiratory cardiovascular diseases 3105 1714, respectively.

Associations between short-term exposure to fine particulate matter with ischemic stroke mortality and the role of green space: a time-series study in Zibo, China

Journal of Global Health, Journal Year: 2025, Volume and Issue: 15

Published: March 21, 2025

Previous studies on associations between short-term exposure to fine particulate matter (PM2.5) and ischemic stroke (IS) mortality reported inconclusive results. Additionally, whether how PM2.5 green space interact precipitate IS deaths remains unclear. We aimed examine the impacts of role in association. collected data daily deaths, concentrations, monthly normalized difference vegetation index (NDVI) Zibo City from 2015 2019. Generalised additive models were adopted investigate mortality, subgroup analyses used effect modification by population characteristics. Stratified levels joint model conducted test interactions mortality. A total 10 799 included our study. Exposure was associated with an increased risk odds ratios (ORs) 1.0263 (95% confidence interval (CI) = 1.0017, 1.0516) for each interquartile range (IQR) increase lag0 1.0317 CI 1.0016, 1.0627) lag01. The links not significantly different across genders, ages, or zones. Furthermore, results showed that effects higher low space. Specifically, IQR PM2.5, ORs CIs) death level high NDVI 1.0287 1.0019, 1.0563) 0.9934 0.9296, 1.0615), respectively. In addition, exhibited significant interactive relative excess due interaction (REOI) greater than 0. Our findings increasing there synergetic lack greenness suggest expanding spaces, such as park coverage street greening, along regulating industrial emissions reduce levels, can help prevent premature IS.

Assessing the Spatial Equity of Urban Park Green Space Layout from the Perspective of Resident Heterogeneity

Sustainability, Journal Year: 2024, Volume and Issue: 16(13), P. 5631 - 5631

Published: June 30, 2024

Urban park green spaces (UPGS) are essential resources for improving the urban ecological environment and meeting residents’ recreational needs. However, during rapid urbanization, layout of UPGS often exhibits spatial inequity, with significant differences in enjoyed by resident groups different socioeconomic attributes. Accurately assessing equity (the equal accessibility UPGS) is crucial optimizing resource allocation promoting social equity. This study takes main area Nanjing as an example utilizes location-based service (LBS) data multi-source geographic to conduct in-depth characterization attributes, behaviors, space at street scale. By constructing indicators heterogeneity supply–demand matching degree, it reveals among locations explores correlation between The finds that generally poor central low-income communities. higher degree diversification attributes leads a lower level their streets. results big analysis verify impact on layout. issues from perspective heterogeneity, providing new ideas evidence resources.

Re-envisioning par for the course: an assessment of desert golf sustainability from a landscape perspective

International Journal of Sustainable Development & World Ecology, Journal Year: 2024, Volume and Issue: unknown, P. 1 - 16

Published: Oct. 10, 2024

Despite providing valuable ecosystem services (benefits people derive from nature), desert golf courses consume enormous amounts of water and can exacerbate scarcity in drylands. Yet, few studies have assessed the sustainability a landscape perspective, which centers on linkages among pattern, services, human well-being. Focusing Phoenix Metropolitan Area (PMA) USA, global epicenter, this study investigated relationships course spatial use, environmental justice. Our analysis revealed that there are 210 PMA, together making up roughly 3.5% total regional demand. Furthermore, we found high-income brackets greater access to benefits provided by than those low-income brackets. To improve sustainability, need design use less provide wider range beyond game golf, including climate regulating cultural services. Golf should be considered explicitly sustainable design, with particular emphasis diversity accessibility they context.
