Summary: This study evaluated the land carbon opportunity cost (COC) of 20 categories of crops and livestock in 30 provinces of China, with results showing beef having the highest COC. As latitude decreases, both land COC and crop yield per unit area increase, but the former increases at a much higher rate than the latter.

Summary: The study proposes a mangrove sustainability index (MSI) to assess the impact of sea level rise and land use on mangrove habitats. The results show that dual stressors would reduce the extent of mangroves and affect habitat quality, landscape pattern, and protection ratio. Unsustainable mangrove distribution sites can be reversed to sustainable sites through improvements in land use policies.

Summary: The study found that land transfer and consolidation have a significant impact on land fragmentation. If transferred plots cannot be merged and consolidated, it may increase the fragmentation index. Only when transferred plots are adjacent, merged, and consolidated, the fragmentation index can be significantly reduced.

Summary: In this article, a deep learning-based model called Dual-Net is introduced for generating land cover maps. The authors created a training dataset for China using a voting strategy based on three existing land-use and land-cover products. They designed the Dual-Net model to utilize dual-date images for map generation and reduce the need for continuous temporal sequences or separate cloud detection. A new validation dataset called CSVD was also created for China. Extensive experiments demonstrated that the Dual-Net model outperforms existing products and produces fine-grained segmentation results.

Summary: This study evaluated arable land ecosystem services capacity and arable land-use intensity, highlighting a lack of coordination between evaluation studies leading to challenges in developing management policies. Results showed that land-use change decreased arable land productive-capacity in a significant number of Chinese counties, particularly in central and southern regions and major grain-producing provinces, indicating the need for better coordination. The study provides insights into the interrelations between natural conditions and arable land-use patterns, emphasizing the importance of addressing challenges for exploring sustainable arable land use paths.

Summary: This paper measures the industrial land use efficiency (ILUE) in China and explores its spatial-temporal characteristics and influencing factors using a stochastic frontier analysis (SFA) method. The results show that ILUE levels in China are increasing, with the east having the highest efficiency and the west surpassing the northeast in recent years. Factors such as enterprise ownership structure, industrial specialization, and local financial pressure play key roles in influencing ILUE.

Summary: This study developed an approach to identify the carbon emissions peak (CEP) status of provincial areas in China and analyze the main factors influencing emissions trends. The results categorized the areas into four clusters based on their emissions changes. To balance efficacy and fairness, scores were assigned to the trends and influencing factors, and the areas were classified into different stages of progress toward CEP. This classification method can be applied by other developing countries as well.

Summary: Visible and near-infrared (Vis-NIR) spectroscopy can provide a rapid and inexpensive estimation for soil organic carbon (SOC), but external environmental factors can affect the accuracy of the model. The external parameter orthogonalization (EPO) algorithm was investigated to eliminate interference from external parameters, with moisture being the most significant factor. The study showed that different EPO development methods can balance model performance and cost effectively.

Summary: Understanding the impact of urban compactness on ecosystem services is important for sustainable spatial planning. This study explored the effects of urban compactness on four ecosystem services in the Wuhan metropolitan area in China. The results showed that urban compactness has a negative correlation with food production, carbon storage, and habitat quality, but a positive correlation with recreation service. The geographically weighted regression model effectively identified spatial heterogeneity, while the multiscale geographically weighted regression model revealed local relationships and spatially non-stationary associations. The contributions of different urban compactness factors to ecosystem services varied considerably.

Summary: This study investigates the spatial effect of public service accessibility on housing prices and proposes a new methodological framework to understand housing equity issues. The results show that public service facilities have a capitalisation effect on housing prices, and larger facilities have a more significant clustering effect. The spatial association detector model has a greater explanatory power than the geographical detector model and can identify the driving factors of housing prices. This study provides valuable insights for urban environmental planning and local real estate planning.

Summary: Accurately mapping soil organic carbon (SOC) is important for evaluating carbon storage and soil quality, but the high spatial heterogeneity and non-linear relationship with covariates in floodplain farmland pose challenges to digital soil mapping. This study used samples from a town near Han River to determine the main factors controlling SOC and reveal their effective ranges, and employed the gradient boosting decision tree (GBDT) model and partial dependence plots for SOC mapping. The results showed that GBDT outperformed linear regression, with the distance from the river identified as the most important factor. Furthermore, the study highlighted the effective ranges of various environmental variables and their impact on SOC. These findings contribute to understanding SOC spatial patterns, carbon sequestration, and precision agriculture.

Summary: Visible-to-near-infrared (vis-NIR) and mid-infrared (MIR) spectroscopy are widely used to estimate soil organic carbon (SOC). The fusion of vis-NIR and MIR data can provide accurate prediction for SOC as the individual sensor range may lack important features. Six data fusion strategies were compared, with PI-CNN achieving the best accuracy (validation R2 = 0.84) for SOC estimation. The better performance of PI-CNN over DC-CNN demonstrates the necessity of using different kernel sizes in the CNN network for fusing vis-NIR and MIR spectral data. The deep-learning fusion method based on PI-CNN is an efficient tool for integrating data from multiple sensors in soil spectral modeling.

Summary: The accessibility of public general hospitals and spatial vertical equity are not well understood in developing countries. This study proposes a theoretical framework to investigate the accessibility of public general hospitals and spatial vertical equity based on demographic dimensions. The results show significant spatial heterogeneity in hospital accessibility and suggest that the spatial distribution of hospitals does not consider communities with a high proportion of minors and seniors. Minors face greater inequities in healthcare access compared to seniors. These findings have important policy implications for creating a more equitable urban form and sustainable healthcare system.

Summary: This study proposes an automatic crop classification strategy (ACCSH) that combines the geographic detector technique, random forest average accuracy model, and random forest classification model to automatically realize large-scale crop classification with high accuracy. By calculating spectral and textural indexes to quantify crop growth characteristics and environmental variables, an adaptive spatial heterogeneity mining method is used to identify spatial homogeneous zones with significant differentiation of crop growth characteristics. Classification indexes are then optimized independently within each zone based on correlation analysis and random forest average accuracy. Random forest is used to classify the target crop in each zone separately. The ACCSH is applied to wheat and corn classification in northern France, and the results show improved accuracy compared to global-scale classifications. The index optimization strategy in ACCSH also demonstrates superiority over non-optimized indexes.

Summary: This study used geographical detector methods to explore the effects of natural factors, human activities, and their interactions on farmland soil organic carbon density (SOCD) and its sequestration rate (SOCDSR). The results showed that both natural factors and agricultural management have an impact on SOCD and SOCDSR, and the interaction effects of environmental variables are often more influential than the individual variables.
