Cropland Suitability–Use Mismatches and Differentiated Zoning Regulation in the North China Plain
Cropland distribution is often shaped by historical cultivation patterns rather than natural suitability, leading to mismatches between actual land use and agricultural production potential. However, their extent and spatial characteristics remain insufficiently understood in the North China Plain, one of China's most important grain‐producing regions. To address this issue, this study developed an integrated framework combining cropland suitabil…
Spatial Simulation of Cropland Abandonment Risk and Grain Production Losses in China
Cropland abandonment has become a widespread phenomenon in China, posing a potential threat to national food security. Despite its growing prevalence, a comprehensive understanding of abandonment risk and the associated potential grain losses remains limited, and effective early warning mechanisms are notably lacking. This study analyzes the spatiotemporal evolution of abandoned croplands, simulates cropland abandonment risk using machine learnin…
Soil Microbial Community Composition and Diversity Response to Varying Farmland Types
Elucidating soil microbial community responses to different farmland types in metropolitan suburbs is vital for optimizing crop production management and preserving soil health. This study investigated four farmland types: dryland (DL), irrigated land (IL), paddy land (PL), and orchard (OL). Through high‐throughput sequencing and statistical methods including one‐way ANOVA and multiple comparisons, we compared soil physicochemical properties with…
From efficiency boundaries to structural diagnosis
Chaihu Shugan San exerts antidepressant effects in female mice by suppressing hippocampal IL-6 and activating the cAMP-CaMKII-BDNF pathway
Promoting or inhibiting? The impact of farmland use transition on rural household income
Insights from land sparing and land sharing frameworks for land productivity degradation governance in the Yangtze River Delta urban agglomeration, China
Land degradation due to mismanagement is widespread globally and may threaten the achievement of several UN Sustainable Development Goals. Yet the differences in land productivity degradation under various land management patterns (land sparing vs. land sharing) are poorly known. In this research, we used remote sensing data to develop a machine learning model for assessing the risk of land productivity degradation and interpreted the model using…
Spatio-Temporal Variation and Its Driving Forces of Soil Organic Carbon along an Urban–Rural Gradient
Rapid urbanization has reshaped land cover and the ecological environment, potentially improving or deteriorating soil organic carbon (SOC). However, the response of SOC to urbanization has not yet been fully exploited. Herein, by using the land-use transfer matrix, the Sen & Mann-Kendall tests, the Hurst index, and a geographical and temporal weighted regression (GTWR) model, as well as an urban-rural gradient perspective, we assessed the dynami…
