Effective management of large basins necessitates pinpointing the spatial and temporal drivers primary index exceedances urban risk factors, offering crucial insights for basin administrators. Yet, comprehensive examinations multiple pollutants within Yangtze River Basin remain scarce. Here we introduce a pollution inventory clusters surrounding Basin, analyzing water quality data from 102 cities during 2018–2019. We assessed exceedance rates six pivotal indicators: dissolved oxygen (DO), ammonia nitrogen (NH3–N), chemical demand (COD), biochemical (BOD), total phosphorus (TP), permanganate (CODMn) each city. Employing random forest regression SHapley Additive exPlanations (SHAP) analyses, identified spatiotemporal factors influencing these key indicators. Our results highlight agricultural activities as contributors to all indicators, thus them leading source in basin. Additionally, coverage, livestock farming, pharmaceutical sectors, along with meteorological elements like precipitation temperature, significantly impacted various indicators' exceedances. Furthermore, delineate five core components through principal component analysis, which are (1) anthropogenic industrial activities, (2) practices extent, (3) climatic variables, (4) rearing, (5) polluting sectors. The were subsequently evaluated categorized based on components, incorporating policy interventions administrative performance region. analysis advocates customized strategy addressing discerned especially presenting elevated levels.

Effective water management in large river basins requires a comprehensive understanding of policy effectiveness and regulatory frameworks. However, quantitative assessments water-related policies remain limited. Here, we propose novel framework for evaluating basins, providing an intuitive systematic approach decision-makers. Using the Yellow River Basin-the second-largest basin China-as case study, constructed database 1271 spanning 68 cities. We assessed completeness nine representative policies, identifying key gaps environment governance. To evaluate effectiveness, developed system integrating two subsystems: resource utilization treatment, incorporating climatic, economic, industrial factors. Our findings reveal that governance were more effective than those targeting utilization, though their impact was delayed by one to years. Furthermore, risk-based analysis pinpointed critical challenges each city, offering actionable insights optimization. This provides robust scalable assessing complex with global applicability improving

Scientific measurement and analysis of the spatial temporal distribution characteristics agricultural carbon emissions (ACEs) influencing factors are important prerequisites for formulation reasonable ACEs reduction policies. Compared with previous studies, this paper fully considers heterogeneity rice emission coefficients, measures analyzes in Jiangsu Province from three sources, including land use, cultivation, livestock poultry breeding, explores clustering patterns driving factors, which can provide a reference low-carbon production. The results indicate that 2005 to 2020, Jiangsu's showed decreasing trend, an average annual decrease 0.32%, while density (ACED) increasing increase 0.16%. area highest values is concentrated northern region Jiangsu, areas ACED distributed southern region. have been strengthening.

Sponge cities are actively being built in China to combat urban flooding, and 30 pilot (regions) have been established since 2015, serving as a guide for further research. In order examine the intrinsic links between (regional) characteristics, planning, sponge city construction metrics, ecological carrying capacity, sustainable development, this study integrates big data machine learning. For evaluation of schemes, we combined Artificial Hierarchical Processing (AHP), Gray Correlation Analysis (GCA), Back Propagation Neural Networks (BPNN) into multi-scale model-coupled qualitative quantitative multiple models coupling system. An system (ESSCC), which can be used on multilingual system, index based capacity development developed. The could advance assessment optimization plans accordance with local conditions from perspectives guaranteeing function, ensuring baseline natural resource utilization environmental safety quality, safeguarding development. is expected serve an effective scientific basis plan formulation, offer direction technical support promotion cities.
