A Dual-Factor-Driven Temporal Network for Pixel-Level NDVI Prediction in the Hulunbuir Grassland

Normalized Difference Vegetation Index (NDVI) is an important remote sensing indicator for characterizing vegetation growth status and ecosystem changes. Improving NDVI prediction accuracy is of great significance for regional ecological monitoring and conservation. However, exis...

Resolving systematic errors in sulfate source apportionment: a field-validated kinetic isotope fractionation framework

Abstract. Sulfates are critical constituents of atmospheric fine particulate matter (PM2.5) that significantly influence air quality and climate dynamics. While stable isotope fractionation analysis is a powerful tool for tracing atmospheric sulfate formation mechanisms, conventi...

Spatiotemporal Dynamics and Zoning Optimization of Territorial Functional Adaptation in the Yunnan–Guangxi Border Region of China from a Development–Security Perspective

From the perspective of coordinating development and security for high-quality development in border regions, this paper focuses on the adaptation relationship between development and security functions in the Yunnan–Guangxi border region. The study aims to characterize the spati...

Machine learning-enhanced 4DVar assimilation for winter wheat yield estimation

Context Accurate crop yield estimation is crucial for ensuring food security, promoting sustainable agriculture, and optimizing management practices. However, integrating remote sensing data with crop models remains challenging, largely due to the inability of traditional data as...

Beyond the factor-driven paradigm: Spatiotemporal dynamics and system coupling of agricultural transition in Henan Province, China

The core of agricultural transition lies in changes to the various components of the agricultural systems and their interactions. Drawing on the social-ecological-technological systems (SETS) framework, this study developed an “element coupling–external manifestation” analytical...

Reconciling nitrogen fertilization effects on soil nitrification with acidification

Nitrogen (N) fertilization supports nearly half of the global population but disrupts the N cycle. While N addition is assumed to stimulate soil nitrification by increasing substrate supply and nitrifier activity, it may also inhibit nitrification via soil acidification. Resolvin...

The pivotal role of the food service industry in alleviating urban segregation and boosting city vitality

Abstract Urban segregation challenges the sustainable and inclusive development of cities, yet little is known about how to address it effectively. This study examines how restaurants in Chengdu, China, a city renowned for its vibrant food culture, shape social interactions in da...

From Spatial Evolution to Low-Carbon Transition: Regional Heterogeneity and Stage Diagnosis of Carbon Emissions Across 19 Urban Agglomerations in China

Understanding the spatiotemporal dynamics of carbon emissions and developing differentiated governance strategies for urban agglomerations are essential for achieving regional low-carbon transformation. This study aims to identify the spatiotemporal patterns, driving mechanisms,...

Divergent Blue Carbon Trajectories in the Yellow River Delta Post‐1976 Diversion: Hydrological Stability and Human Disturbance Contrasts Revealed by Multi‐Source Remote Sensing (1984–2023)

ABSTRACT Coastal wetlands are critical blue carbon sinks, yet their spatiotemporal dynamics under environmental change remain insufficiently quantified. Taking the Yellow River Delta (YRD) as a natural laboratory, this study synthesizes multi‐source remote sensing data, including...
