Rapid economic and social development has triggered competition for limited land space from different industries, accelerating the evolution of Beijing’s urban landscape types. The increase in impermeable surfaces decrease ecological have led to an impact on thermal environment. Since previous studies mainly focused a single environment lacked exploration combined multiple landscapes, this study applied standard deviation ellipses, Pearson correlation analysis, surface temperature (LST) profile hot spot analysis comprehensively explore influence evolving production–living–ecological (PLES) pattern LST. results show that average LST various spaces continued before 2009 decreased slowly after 2009, with highest being living space, followed by production lowest each year. spatiotemporal shift path is consistent trajectory center gravity Beijing; positively correlated (LS) negatively (PS) (ES).

Greenspace exposure metrics can allow for comparisons of green space supply across time, space, and population groups, inferring patterns variation in opportunities people to enjoy the health recreational benefits nearby environments. A better understanding greenspace differences various spatial scales is a critical requirement lessening environmental disparities. However, existing studies are typically limited single city or selected cities, which severely limits use results measuring systemic national regional scale that might need policy at above individual planning level. To close this knowledge gap, our study aims provide holistic assessment multi-scale provinces, counties, towns, land parcels whole China. We mapped nationwide fractional coverage 10 m with Sentinel-2 satellite imagery, then modeled population-weighted examine scales. Our show prominent scaling effect administrative divisions China, suggesting, as expected, an increase heterogeneity finer also identify asymmetric pattern difference between coverage, geo-demographic demarcation boundary (i.e., along Heihe-Tengchong Line). In general, rate will overestimate more realistic human East China while underestimating West further found that, recently urbanized areas have much than older urban areas. provides spatially explicit metric discovering difference, enhance governments' capacity quantify justice, detect vulnerable risk hotspots, prioritize management supra-city scale, monitor balance demand.

Increasingly people, especially those residing in urban areas with the heat island effect, are getting exposed to extreme due ongoing global warming. A number of methods have been developed, so far, assess vulnerability different locations across world concentrating on diverse aspects these methods. While there is growing literature, thorough review studies that compare, contrast, and help understand prospects constraints assessment scarce. This paper aims bridge this gap literature. systematic literature preferred reporting items for reviews meta-analyses (PRISMA) approach utilized as methodological approach. PRISMA an evidence-based minimum set meta-analyses. The results analyzed three aspects—i.e., indicators data, modelling approaches, validation approaches. main findings disclose that: (a) Three types commonly used—i.e., demographic properties socioeconomic status, health conditions medical resources, natural built environmental factors; (b) Heat indexing models, equal weighting method, principal component analysis used approaches; (c) Statistical regressions correlation coefficients between adverse outcomes but performance varies studies. study informs policy generates directions prospective research more accurate method development.

To better understand the phased changes, development direction and planning challenges of urban green space (UGS) in response to urbanization process changing goals, this study examines spatiotemporal variations, landscape patterns driving forces UGSs Changchun from 1990 2020. The results indicate that evolution may be largely categorized into three stages, considerable decline, balance between increase decrease, surge increase, accompanied by obvious changes landscape. Several factors have contributed these including natural, greening policies. Early resulted encroachment fragmentation a amount UGS; however, as building priorities changed, UGS has increasingly gained attention. In third decade research period, greatly expanded, demonstrating some achievements construction under background ecological civilization. Knowledge dynamics provides reference for planning, which also helps cities respond call land "ecological use, security development" during China similar countries.

There is worldwide concern about how climate change -which involves rising temperatures- may increase the risk of contracting and developing diseases, reducing quality life. This study provides new research that takes into account parameters such as land surface temperature (LST), urban heat island (SUHI), hotspot (UHS), air pollution (SO2, NO2, CO, O3 aerosols), normalized difference vegetation index (NDVI), building (NDBI) proportion (PV) allows evaluating environmental establishes mitigation measures in future developments could improve life a given population. With help Sentinel 3 5P satellite images, we studied these variables context Granada (Spain) during year 2021 to assess they affect diseases (stomach, colorectal, lung, prostate bladder cancer, dementia, cerebrovascular disease, liver disease suicide). The results, corroborated by statistical analysis using Data Panel technique, indicate LST, SUHI daytime UHS, SO2 NDBI have important positive correlations above 99% (p value: 0.000) with an excess diseases.
