Summary: Studying the production intensity of ecological footprint is crucial in the ecological compensation strategy for designated industries, especially in identifying high-polluting industries. Environment-extended input-output (EE-IO) tables are useful for analyzing pollution and land occupation within economic sectors. By using ecological footprint (EF) and input-output tables (IOTs), this study analyzed China's EFPI and its flow among sectors in 2005, 2010, and 2015. The results showed a downward trend in the average total pollution coefficient (TPC) component and net embodied EFPI transfers from 2005 to 2015. The electricity, heat, gas, and water sector (S11) and the agriculture sector (S1) had significant contributions to TPC and net embodied EFPI transfers. Recommendations were made to impose an ecological tax and control high-EFPI industries for optimization.

Summary: This study assessed the effects of different fertilization regimes on carbon sequestration and greenhouse gas emissions in apple orchard production systems in the Loess Plateau, China. The results showed that organic fertilizer substitution increased soil organic carbon and decreased nitrate nitrogen and ammonium nitrogen concentrations. There were no significant differences in nitrous oxide emissions among fertilization strategies, but compared to the treatment with 800 kg N/ha, treatments with 400 kg N/ha and 200 kg N/ha + 200 kg organic fertilizer/ha significantly reduced nitrous oxide emissions. The study suggests that reducing the amount of nitrogen fertilizer and partially substituting with organic fertilizer can mitigate climate change through carbon sequestration, reduction of nitrogen residues, and greenhouse gas mitigation in apple production in the Loess Plateau, China.

Summary: A reasonable allocation of carbon emission quotas is crucial for improving the national unified carbon trading market. The research findings show that certain eastern provinces bear a greater responsibility in terms of historical carbon emissions, and the transfer of carbon emissions from energy-rich to energy-demanding regions has exacerbated regional development imbalance. Carbon emission demands are fulfilled in some provinces located in the coastal regions of the southwest and southeast, while certain provinces in the northeast express the lowest satisfaction with their carbon quota allocation, requiring a greater burden of carbon emission reduction in the future.

Summary: Accurate quantification of soil organic carbon (SOC) in urban areas is crucial for effective city management and understanding anthropogenic changes. Visible and near infrared (vis-NIR) spectroscopy has been proven to be a time and cost-effective method for monitoring SOC content. The relationships between SOC and spectral data in urban soils are still unknown. This study evaluated the performance of multiple stratification strategies for predicting SOC content in urban soils. The results showed that stratification based on land-use/land-cover (LULC) improved the prediction performance, with the highest performance achieved by the Cubist model. Areas with high SOC values were mainly located in the city center. Stratification by LULC class is a promising strategy for estimating SOC in urban soil spectral libraries.

Summary: Visible and near-infrared reflectance (VNIR) spectroscopy is a promising alternative to detect heavy metal contamination in suburban soils. This study explored the spatially varying relationships between soil chromophores and heavy metals and investigated the feasibility of using multi-scale geographically weighted regression (MGWR) for heavy metal estimation with VNIR. The MGWR method outperformed its competitors, resulting in an increase in the coefficient of determination and a decrease in the residual sum of squares. The spatial correlation between heavy metals and TFe2O3 was found to be the main reason for the successful estimation of Cr and Ni using VNIR.

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: Urban form, particularly urban functional form, is crucial for urban planning, construction, and management. Recent advancements in characterizing urban functional form have enabled the quantification of its relationship with urban carbon emissions. Utilizing data from 178 Chinese cities, this study examined the relationship between urban CO2 emissions and five categories of urban form: compactness, extension, fragmentation, irregularity, and concentration. The findings revealed that all five categories significantly impact total CO2 emissions (TCE), while four categories (excluding fragmentation) significantly affect per-capita CO2 emissions (PCE). Specifically, an increase in functional compactness index (FCI) by 1% leads to a decrease in TCE and PCE by 0.79% and 0.34% respectively. Carbon emission reduction policies should consider the topographical environment, spatial structure, and industrial structure of cities. FCI has the greatest carbon emission reduction effect in plain and single-center cities, while form planning and control are crucial in hilly and mountainous cities, multi-center cities, and highly industrialized cities. This study emphasizes the theoretical and practical significance of adjusting urban functional form for low-carbon city development.

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.
