Spatiotemporal impacts of human activities and socio-demographics during the COVID-19 outbreak in the US

BMC Public Health, 2022
Background Understanding non-epidemiological factors is essential for the surveillance and prevention of infectious diseases, and the factors are likely to vary spatially and temporally as the disease progresses. However, the impacts of these influencing

Landscape Fragmentation Driven by Land Use Change Dominates the Spatiotemporal Heterogeneity of Non‐Point Source Pollution Loads in Human‐Intensive Basins: A Case Study of the Dongjiang River Basin, China

Land Degradation &Development, Volume 37, Issue 14, Page 10440-10463, 30 August 2026.
ABSTRACT Landscape fragmentation may influence the spatial distribution and temporal variation of non‐point source (NPS) pollution by altering hydrological processes, pollutant transport pathways, and ecosystem service functions. However, under the combined effects of natural factors (e.g., precipitation, topography) and anthropogenic factors (e.g ...

Linking Grain Planting Patterns to Multidimensional Agricultural Sustainability: Evidence From Landscape Metrics and Spatial Analysis in China

Earth's Future, Volume 14, Issue 8, August 2026.
Abstract Changes in grain planting patterns have been closely linked to substantial increases in crop yields. However, their relationships with the Sustainable Development Goals (SDGs) remain unclear, particularly across multiple SDG dimensions. Clarifying these relationships could help inform progress toward food security and the SDGs.

Spatiotemporal Nonstationary Robust Modeling Between Luojia1-01 Night-Time Light Imagery and Urban Community Average Residence Price

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
This article is the first to propose a novel spatiotemporal nonstationary robust modeling between high spatial resolution Luojia1-01 night-time light intensity (NTLI) and urban community average residence price (UCARP), which encodes the spatiotemporal ...

Spatiotemporal Modeling and Composite Indices for Pandemic Preparedness: A Novel Geospatial‐Temporal Approach

Geographical Analysis, Volume 58, Issue 3, July 2026.
ABSTRACT This study proposes a geographically and temporally weighted random forest (GTWRF) model for explanatory spatiotemporal analysis of COVID‐19 outcomes. GTWRF extends the conventional geographically weighted random forest by incorporating spatial and temporal dependencies through an adaptive Gaussian weighting scheme.

Urban Shrinkage and Surface Urban Heat Islands: Does Population Decline Lead to Cooling? A Spatiotemporal Analysis of China's 89 Shrinking Cities (2001–2019)

Earth's Future, Volume 14, Issue 3, March 2026.
Abstract Numerous studies have examined how urban expansion exacerbates Surface Urban Heat Island intensity (SUHII), yet limited attention has been paid to whether and how urban shrinkage mitigates SUHII. This study employed multiple models to analyze the spatiotemporal evolution of surface urban heat island (SUHI) and its driving factors in 89 ...
