No risk existed during a short metro ride of 2 min, and the infection risk increased with the talking durations/coughing frequencies, co-travel durations, and crowdedness levels. The infection risk for seated passengers was higher than that for standing passengers due to the shorter interpersonal distance for the former. Over 80 % of infections occurred within 1.5 m of the source passenger, and 100 % occurred within 2.6 m in metro carriages with different crowdedness levels. A safe social distance of 2.6 m from a potential source passenger is recommended in metro carriages.

Therefore, the implementation of flood risk assessments for urban subway systems is becoming urgent. In this study, we proposed a novel framework for evaluating subway flood risks by comprehensively considering the hazard, exposure, vulnerability and coping capacity of subway systems for urban flooding. The Beijing subway system was chosen in a case study. Three hazard indicators, eight exposure indicators, five vulnerability indicators and seven coping capacity indicators, were incorporated into a multi-index framework. The flood risk levels of each subway line and subway station were obtained. Furthermore, Pearson’s correlation analysis and random forest (RF) regression combined with the SHapley Additive exPlanations (SHAP) method were adopted to reveal the correlation between each evaluation indicator and the flood risk level and quantify their contributions to the change in flood risk. The findings revealed that for the Beijing subway system, the highest- and high-risk zones accounted for 26.16% of the total subway area. The top ten flood risk stations were located mainly in the central urban area. Compared with the traditional assessment framework, incorporating coping capacity indicators into the framework decreased subway flood risk levels in many districts of Beijing. Among all indicators, passenger flow, node degree, betweenness centrality, subway line density and subway line proximity play important roles in determining the subway flood risk.

The modeling framework integrates a comprehensive set of indicators encompassing landscape configuration, building morphology, surface biophysical properties, and spatial contextual factors. While reaffirming the effects of impervious surfaces and vegetation, the analysis reveals the critical role of neighborhood-scale spatial interactions. The proposed spatial contextual indicators, which capture the functional composition of surrounding zones across multiple adjacency levels, exhibit strong explanatory capacity. SHapley Additive exPlanations (SHAP) analysis shows that these indicators account for 26.3% of the total thermal contribution among the top 15 predictors—comparable to building morphology metrics and, in some cases, surpassing direct vegetation indices such as NDVI. Additionally, a reinforcement learning approach based on Soft Actor-Critic algorithm was employed to identify optimal spatial configurations for minimizing average LST. Simulation outcomes suggest that strategically increasing neighborhood green spaces, reducing industrial land proportions, and adjusting spatial arrangements of residential, commercial, and public zones can effectively mitigate urban warming.

After dimensionality reducion using principal component analysis method, a robust WRSDS-CR evaluation indicator system was established. Additionally, the fuzzy comprehensive evaluation model was developed to quantify WRSDS-CR and spatial econometric models were employed to explore its spatial characteristics. A case study was performed in Chuxiong Prefecture during the 2009-2012 extreme drought. The key findings are: (1) The WRSDS-CR in Chuxiong Prefecture was classified at Level II, with its fluctuation primarily influenced by the operation mechanism. (2) Among the counties, Nanhua exhibited the highest WRSDS-CR, while Lufeng recorded the lowest. Chuxiong City showed the most significant improvement.

However, existing extraction models face challenges in capturing the temporal impervious surfaces dynamics and identifying reverse changes, mainly due to regional heterogeneity and temporal instability. Moreover, the impacts of these changes on surface urban heat island intensity (SUHII) trends and its patterns remain unclear. Therefore, this study developed a framework for estimating dynamic impervious surface percentage (DISP) by integrating machine learning and time optimization. The framework was used to quantify the SUHII trend under four types of impervious surface changes (increased, decreased, unchanged, and other). This classification can investigate the distinct thermal environmental responses associated with different DISP. Firstly, spatiotemporal consistency screening and extraction rules were designed to generate training samples. Subsequently, multi-temporal image fusion strategies were implemented, and regionally adaptive impervious surface percentage estimation models were constructed based on multiple feature combinations. Additionally, a time-series correction method was introduced to optimize DISP across different change trajectories. Finally, the dynamic trends of SUHII were captured under time series changes and regional differences, based on various impervious surface change types. The results show that DISP can achieve continuous and accurate estimations (R² = 0.848, RMSE = 0.106), outperforming existing products. Different types of impervious surface changes exhibit distinct thermal responses, with increased DISP intensifying the heat island effects and decreased DISP mitigating them. These effects are more pronounced in tropical and temperate zones than in arid regions. And high-density impervious surfaces also correspond to higher temperatures.
