Blue and green spaces (BGS) play a crucial role in mitigating the urban heat island (UHI) effect by not only lowering land surface temperature (LST) but also regulating microclimate enhancing ecosystem services. In this study, Ningbo City is selected as research area. LST data for years 2014, 2017, 2020, 2023 were retrieved using Landsat 8 imagery processed via Google Earth Engine platform, employing an atmospheric correction approach. Simultaneously, use types classified random forest algorithm. Based on these datasets, Geographically Temporally Weighted Regression model was employed to quantitatively assess spatial temporal impacts of BGS changes UHI effect. The results reveal that (1) from 2014 2023, exhibited consistent decline, while construction expanded significantly, leading gradual increase annual average LST; (2) strong zones primarily concentrated urbanized closely aligned with regions elevated minimum, maximum, values blue significantly lower than those observed cultivated land; (3) variation influence coefficient space greater space, suggesting stronger spatiotemporal heterogeneity its regulatory thermal environment. Additionally, green-to-blue area ratio increased 9.7:1 12.8:1 deviating progressively optimal ecological balance. To promote sustainable development, it imperative strengthen conservation restoration BGS, optimize their configuration through evidence-based planning, ensure long-term stability functions.

Being an essential issue in global climate warming, the response of urban green spaces to air pollution and variability because rapid urbanization has become increasing concern at both local levels. This study explored vegetation Bucharest metropolis Romania from a spatiotemporal perspective during 2000–2024, with focus on 2020–2024 period. Through synergy time series situ data, derived biophysical variables MODIS Terra/Aqua satellite this applied statistical regression, correlation, linear trend analysis assess relationships between their pairwise associations. Green were measured normalized difference index (NDVI), leaf area (LAI), photosynthetically active radiation (FPAR), evapotranspiration (ET), net primary production (NPP), which capture complex characteristics systems (gardens, street trees, parks, forests), periurban forests, agricultural areas. For center (6.5 km × 6.5 km) metropolitan (40.5 40.5 test areas, five-year investigated period, found negative correlations NDVI ground-level concentrations particulate matter two size fractions, PM2.5 (city r = −0.29; p < 0.01, −0.39; 0.01) PM10 −0.58; −0.56; 0.01), as well gaseous pollutants (nitrogen dioxide—NO2, sulfur dioxide—SO2, carbon monoxide—CO. Also, parameters, relative humidity (RH), land surface albedo (LSA) observed. These results show potential improve quality through pollutant deposition, retention, alteration health, particularly dry seasons hot summers. same period analysis, positive solar irradiance (SI) planetary boundary layer height (PBL) recorded. Because summer season’s (June–August) increase ozone, significant (r −0.51, for city −76; area, may explain degraded or devitalized under high ozone research reported temperature 2 m (TA) −0.84; scale −0.90; (LST) p< −0.68, 0.01).

The study of the temporal and spatial characteristics air pollutants in heavily polluted cities is extremely important for analyzing causes pollution achieving a viable means control. Such case Xi’an, typical city Fenwei Plain, China, have remained unclear due to limitations data accuracy research methods. monthly, daily, hourly patterns O3 particulate matter (PM2.5 PM10) are analyzed this using on-site provided by an urban quality monitoring network. analysis variance (ANOVA) method was used compare differences pollutant concentrations during different seasons time periods. distributions O3, PM2.5, PM10 at points following interpolation sites been analyzed. results show that concentration from 12 p.m. 3 significantly higher than morning evening, PM2.5 7 10 were those afternoon. number qualified days less 30 unqualified more 100 2019. There potential risk exposure with associated health risks. Even on same day, can differ significantly. This provides scientific basis reducing exposure. Outdoor activities summer beneficial reduce exposure, outdoor should be curtailed evening winter government formulate public policies activities.

Rapid urbanization worldwide has significantly altered urban climates, creating a need to balance growth with thermal environmental quality for sustainable development. This study examines the relationship between land surface temperature (LST) and characteristics, particularly focusing on how green cover can mitigate heat air pollution increase temperatures. Recognizing predictive value of LST island (UHI) intensity, we analyzed three distinct U.S. cities—Chicago, San Francisco, Phoenix—each characterized by unique climate planning features. investigates atmospheric pollutants (SO2, NO2, CO, O3) Normalized Difference Vegetation Index (NDVI) using regression correlation analyses. The analysis aims elucidate changes in NDVI affect variations temperature. Regression is employed estimate coefficients independent variables quantify their impact LST. Correlation assesses linear relationships variables, providing insights into pairwise associations. also multicollinearity identify potential confounding factors. results reveal significant associations pollutants, NDVI, temperature, contributing our understanding factors influencing dynamics informing change mitigation strategies. observed inconsistencies correlations across cities highlight importance local context studies. Understanding these aid developing tailored policies that consider city characteristics more effective resilience. Furthermore, positive association was consistently obtained LST, indicating increased levels contribute higher temperatures different settings.
