    Spatiotemporal patterns and social determinants of county life expectancy in the Yangtze River Economic Belt by Youming Dong, Mengcheng Wang, Yaya Song, Zeyu Yi, Jiulang Peng, Xiyan Mao, Xianjin Huang, Xianjin Huang

    Published 2025-04-01
    “…BackgroundRevealing the spatiotemporal differentiation characteristics of population life expectancy (LE) and exploring the spatiotemporal heterogeneity in impacts of social determinants of health (SDOH) is a crucial foundation for the scientific allocation of regional public resources and the formulation and implementation of localized public health policies.Materials and methodsThe study focused on 1,068 county-level units in the Yangtze River Economic Belt (YREB) of China, utilizing census data from 2000, 2010, and 2020 to uncover the spatiotemporal differentiation patterns of county-level LE. The Geographically and Temporally Weighted Regression (GTWR) model was employed to analyze the spatiotemporal heterogeneity in impacts of various SDOH on LE and the differences in effects among different types of county-level administrative divisions.Results(1) From 2000 to 2020, the average LE in the counties of the YREB had gradually increased from 72.3 years to 81.3 years, with a spatial pattern of LE showing that the eastern region exceeded the central region, which exceeded the western region. (2) The high-high clusters were primarily concentrated in urban agglomerations, while low-low clusters were predominantly located in the western region of the YREB. (3) Overall, the gender ratio (GR) and family size (FS) negatively impacted LE, while the average years of education (AYE), the logarithm of per capita disposable income [PDI(ln)], per capita housing area (PHA), and healthcare professionals per 1,000 people (PHP) had positive effects. (4) The impact of different SDOH varied across space and time. …”

    Patterns of nutrients and algal biomass in an intermittent Mediterranean river under intense human activity by Gabriela Córdoba-Ariza, Rafael Muñoz-Mas, Ramon J. Batalla, Josep Mas-Pla, Sergi Sabater

    Published 2025-04-01
    “…The limited capacity of these systems to dilute pollutants, along with the extent of water flow interruption, leads to a high variability of nutrient concentrations and algal biomass, with relevant implications for water quality. The temporal and spatial patterns of nutrients—Total Nitrogen (TN), Nitrates (NO3-), Total Phosphorus (TP), and Phosphates (PO43-)—and chlorophyll (as a surrogate of algal biomass) were characterized in a Mediterranean river system to determine their relationship to water flow intermittency and human activities. …”

    “…The results indicate the following: (1) By 2030, the spatial pattern of ecological network under the four scenarios will be concentrated in the east and west, in the north and south, and the middle of the Loess Plateau. (2) The change of land use pattern driven by a single policy has a trade-off effect on the ecological network and is prone to form the phenomenon of “ecological increase–functional lag”.
