Recent studies on the accessibility of sports facilities have rarely considered specific attributes facilities, limiting their ability to define service potential, and often neglected critical aspect equitable access. This study proposed a novel approach based remote sensing images optimize spatial outdoor facilities. Using Shanghai, China, as area, identified four types using deep learning object detection method, which allowed capacities (areas) be measured more precisely. A greedy heuristic algorithm was then developed "trade-off" strategy that seeks facility access by reconciling objectives enhancing ensuring equality weighing benefits utilizing existing resources (school facilities) against necessity developing new ones. The method achieved precision recall rates 88% 96%, respectively, optimization efforts resulted in 73% increase while also significantly reducing Gini coefficient from 0.58 0.34. outperformed random selection all-school-opening strategies. results indicated methodology can effectively create refined datasets for enhance accessibility.

Community regeneration plays a pivotal role in creating human-centered spaces by transforming spatial configurations, enhancing multifunctional uses, and optimizing designs that promote sustainability vibrancy. However, the influence of such on vitality—particularly its heterogeneity nonlinear effects—remains insufficiently explored. This study presents comprehensive framework combines Difference-in-Differences (DID) method with multiple socio-spatial correlated factors, including place agglomeration, individual social perception, offering systematic assessment urban vitality evaluating impact interventions. By leveraging street-level imagery to capture environmental changes pre- post-regeneration, this research applies Gradient Boosting Decision Tree Regression (GBDT) uncover built environment dynamics affecting vitality. Empirical analysis from six districts Suzhou reveals following: (1) A pronounced increase is seen core areas, while peripheral exhibit more moderate improvements, highlighting spatially uneven outcomes. (2) In historically significant areas as Wuzhong, limited gains underscore complex interplay among historical preservation, development trajectories. (3) Furthermore, transformations, variations sky visibility, nonprivate vehicles, architectural elements, introduction glass-wall structures, impacts distinct threshold effects. advances discourse sustainable proposing context-sensitive, data-driven tools reconcile heritage conservation contemporary goals. It underscores need for integrated, adaptive strategies align local conditions, contexts, trajectories, informing policies green, inclusive, digitally transformed cities.

The combination of global climate change and the urban heat island effect has given rise to a deterioration in livability residential districts within cities, posing challenges enhancing health quality environments. Meanwhile, intensification daytime changes temperature humidity rendered sensory representation more pronounced. This study selects Fuzhou City as research case area, which have witnessed discernible warming trend recent years, acquires parameter data at three time periods (early morning, noon, evening) represent phase. Through aerial photography field research, types spatial morphological indicators (buildings I, vegetation II, buildings II) are quantified three-dimensional form area. analysis results show following: ➀ Residential experience two phases humidity: drying phase (WDP) morning cooling humidifying (CHP) afternoon. characteristics correlation with each other. ➁ impact morphology on WDP is minor, whereas, CHP, it influenced by Class II III indicators. exert synergistic regulatory humidity. ➂ Vegetation significant variations areas through its form.
