The urban spatial structure reflects a city's development history, cultural heritage, and socio-economic conditions. A rational urban spatial structure is crucial for urban development. This study focuses on the main urban area of Nanjing, analyzing POI and nighttime light data from 2016 to 2020. Utilizing kernel density estimation and coupling coordination models, it explores the temporal and spatial evolution characteristics of Nanjing's urban spatial structure. Geographic detectors are employed to assess the impact of various factors on this structure. The findings indicate that: (1) Nanjing's urban spatial structure displays a pattern of central aggregation and peripheral expansion, with high brightness concentrated in the urban center and a significant increase in peripheral brightness, signaling initial success in establishing urban subcenters; (2) The coupling relationship between nighttime light brightness and POI density has strengthened, suggesting improved coordination of the urban spatial structure; (3) The evolution of Nanjing's urban spatial structure results from the combined effects of multiple factors, including economic level, population distribution, transportation conditions, and policy planning.

As global urbanization accelerates, the spatial vitality of historical urban areas has become a critical issue in urban regeneration and sustainable development. Some existing spatial vitality evaluation frameworks fail to integrate multiple dimensions effectively, limiting their capacity to capture the dynamic complexity of these areas comprehensively. This study utilizes multi-source big data and deep learning technologies to propose a new multidimensional evaluation system for spatial vitality, improving existing models and systematically analyzing distribution patterns and formation mechanisms. The research results show that: (1) The spatial vitality of Changsha's historical urban area exhibits a distinct “core-periphery” pattern. Core commercial zones show high vitality due to functional concentration, whereas peripheral areas have weaker vitality because of lower physical space quality and limited functional diversity. (2) Through correlation and principal component analyses, five key factors influencing spatial vitality were identified: emotional perception, visual aesthetics, spatial attractiveness, Functionality and Structure, and traffic conditions. (3) Bivariate spatial autocorrelation analysis further revealed spatial clustering effects between spatial vitality and its key factors, emphasizing the potential for enhancing functional diversity and optimizing road traffic conditions in core areas. The study's findings offer scientific guidance for urban regeneration and policy-making, particularly in optimizing spatial layouts, enhancing vitality, and fostering the coordinated development of cultural heritage protection, providing valuable insights for other developing countries.

The history of architectural and urban practices reflects humanity's enduring quest to comprehend and shape its environment, often through the lens of unifying meta-narratives. This paper critiques the tendency to seek cohesive frameworks, drawing from Graham Harman's speculative realism and Bruno Latour's “Principle of Irreduction,” which challenge hierarchical structures in understanding reality. These perspectives underscore the irreducibility and multiplicity of existence, advocating for a paradigm shift that resists determinism and embraces open-endedness. In this context, Adrian Bejan's constructal law offers a compelling alternative for interpreting architectural and urban forms. Constructal theory conceptualizes form and design as evolutionary responses to flow systems, framing architecture as an active participant in the dynamic interplay of environmental, social, and temporal forces. This perspective encourages a reevaluation of architectural practices not as definitive solutions but as iterative processes that engage with complexity and contingency. By integrating constructal theory with contemporary philosophical critiques, this article proposes a poly-narrative of architecture and urbanism that aligns with the fluidity and multiplicity of modern existence. It argues for a departure from static frameworks toward adaptive methodologies that acknowledge the interconnectedness of actors, scales, and temporalities. Ultimately, this approach reframes design as a dialogic process, fostering resilience and innovation in confronting the uncertainties of a rapidly evolving world.
建筑和城市实践的历史反映了人类对理解和塑造环境的持久追求,通常是通过统一元叙事的镜头。本文从格雷厄姆·哈曼(Graham Harman)的思辨现实主义和布鲁诺·拉图尔(Bruno Latour)的“不还原原则”(Principle of irreducour)中,批判了寻求内聚框架的倾向,这些框架挑战了理解现实的等级结构。这些观点强调了存在的不可约性和多样性,提倡一种范式转变,抵制决定论,拥抱开放性。在这种背景下,Adrian Bejan的建筑法为解释建筑和城市形式提供了一个令人信服的选择。建构理论将形式和设计概念化为对流动系统的进化反应,将建筑框架化为环境、社会和时间力量动态相互作用的积极参与者。这种观点鼓励对架构实践进行重新评估,而不是将其作为确定的解决方案,而是作为涉及复杂性和偶然性的迭代过程。通过将建构理论与当代哲学批判相结合,本文提出了一种与现代存在的流动性和多样性相一致的建筑和城市主义的多元叙事。它主张从静态框架转向承认参与者、规模和时间性的相互联系的适应性方法。最终,这种方法将设计重新定义为一个对话过程,在面对快速变化的世界的不确定性时,培养韧性和创新。

Accurate evaluation on residential energy demand is crucial for sustainable energy systems and urban development. Bottom-up approaches are reliable to capture the building energy characteristics. However, the existing bottom-up approaches require large volumes of high-quality residential building data, which are often inaccessible in developing countries like China. This study proposes a bottom-up approach based on prototype residential units to assess energy challenges in urban residential sector of China. By integrating data collection, variable selection, and K-prototype clustering analysis, the method identifies several residential prototypes that can be used for predictions on energy dynamic variation in residential sector. The proposed method is applied in Guangzhou, a major city in southern China, during heat wave events as a case study. The results indicate that both daytime and nighttime cooling loads in the residential sector are significant and should not be overlooked; peak hourly energy demand typically occurs at 7:00 a.m. and 9:00 p.m. The proposed approach provides a scalable framework for forecasting energy demand, supporting policy and urban planning to reduce consumption while enhancing resilience to extreme weather and understanding of energy challenges in China's urban residential sector.

This study explores the interaction between spatial configuration, natural mobility, and visual accessibility in exhibition spaces, an area that remains underexplored. By integrating visibility graph analysis (VGA), intelligent agent simulation (IAS), topological analysis, and field observation, the research examines functional layout and accessibility across four museums. Findings indicate that corridors and pathways, second only to exhibition halls, play a crucial role in spatial mobility. Composite layouts (e.g., circular and L-shaped designs) exhibit superior mean depth and integration, yet connectivity and mean depth demonstrate a nonlinear relationship. Elongated or complex path turns increase cognitive load, complicating navigation, while open passageways promote smoother visitor distribution. Topological analysis effectively identifies optimal nodes, key locations, and path-turn efficiency under accessibility constraints. Visitor dwell time is shaped not only by exhibit content but also by spatial location, entry sequence, and visitor density. Results support the assumption that space syntax models align with real-world visitor flow patterns, yet predictive models fail to fully capture variations in mobility across different timeframes and behavioral contexts. These insights contribute to optimizing museum design for improved visitor experience and spatial efficiency.

Urban tourism space is the primary area where tourism activities occur and a key driver of regional tourism space evolution. To explore the correlation between population aggregation and urban tourism spatial heterogeneity in the big data era, this study focuses on Wuhan's main urban area in 2023. Using the Geographically Weighted Regression model, it analyzes the factors influencing tourism spatial heterogeneity. Additionally, Baidu Heat map data is employed to identify crowd aggregation levels during holidays, revealing the distribution patterns of urban tourism space. The results indicate that (1) factors derived from the GWR model significantly influence the number of tourism spaces in Wuhan, with evident spatial differences; (2) based on the spatial matching of heterogeneity factors and crowd aggregation levels, urban tourism space can be categorized into six types, including five core tourism spaces and other scattered spaces. This research highlights the spatial heterogeneity of urban tourism in Wuhan and provides a scientific basis for the transformation and quality improvement of urban tourism space by exploring the impact of population activity density.

Vitality transfer patterns are essential for creating vibrant, sustainable cities, yet their dynamic changes over time remain underexplored. Taking Nanjing as a case study, this study employed 24 h of location-based service data as a time series to explore the vitality transfer pattern within a day from both distribution and aggregation perspectives. Spatial dependence decay patterns were detected using residual clustering relationships, and the LightGBM model was used to explore the relationship between vitality transfer and 50 factors in five categories: transportation, function, economy, morphology, and geography. The results show that the urban vitality distribution has a polycentric agglomeration pattern, which goes through four periods in a day. Vitality transfer is the cyclical process of transformation from one aggregated state to another. The spatial dependence was maximized at 0.75 km2. The magnitude of vitality fluctuation is strongly influenced by factors such as morphology, transportation, and function. Spatial differences in factors combine to drive vitality transfer in distribution and aggregation, with factors such as accessibility and building age diversity influencing distribution, and factors such as accessibility and POI diversity altering aggregation. This study supports the rational design of vibrant urban spaces and promotes effective vitality transfer and sustainable urban development.

This study examines the structural characteristics and technical principles of the hybrid framing cantilever bridges along the Longchuan River in Tengchong, Yunnan, China, taking the Yezhuqing Bridge as a case example. Such bridges integrate diverse construction techniques—including inclined cantilevers, iron chains, three-sided arches, and strut frames—showcasing the craftsmanship characteristic of a region shaped by cultural blending. This paper first analyzes the structural design and mechanical principles based on the bridge's form, and then examines construction details to understand material selection, reconstruct fabrication methods, and explore craftsmanship thinking. The findings reveal that in the structural design, iron chains, strut frames, and three-sided arches each take on distinct load-bearing roles in a cantilever bridge, enabling it to achieve a large span. By coordinating structural components, this bridge type does not require scaffolding during construction, instead relying on the components themselves for mutual support throughout the building process. In terms of construction details, skillful arrangement of elements like wooden pegs enhances convenience and precision during construction, while ensuring overall integrity and stability. Additionally, this study examines existing structural vulnerabilities and past restoration issues, providing insights for future conservation efforts.

China's rapid urbanization presents significant challenges for rural construction and resource management, often prioritizing economic gains over climate adaptability and energy efficiency. This study focuses on traditional Huizhou houses, integrating energy consumption and comfort analysis into the early design stages. Initial simulations using the Universal Thermal Climate Index (UTCI) established a baseline model for comparison. Through the Wallacei_X plugin, optimized designs achieved a 19.88% reduction in energy use intensity (EUI) and a 9.37% improvement in summer outdoor comfort (UTCI_H) compared to the baseline. Further analysis along the Pareto frontier using Scikit-learn demonstrated high predictive accuracy with XGBoost (F1 scores: 0.80 for 4-side houses, 0.78 for 3-side houses). To enhance interpretability, SHapley Additive exPlanations (SHAP) analysis explored nonlinear relationships between design variables and building performance, while coupling analysis examined the spatial relationships between houses and their environmental impact. In the final validation, the proposed workflow effectively linked building performance prediction with design optimization, achieving a 26% performance improvement over the original site plan. This integrated approach enables rapid performance evaluations, reduces costs, and provides practical design references. It highlights the potential of combining genetic algorithms and machine learning to drive sustainable rural development.

Transit-oriented development (TOD) is increasingly recognized as a key strategy for enhancing transportation efficiency, environmental sustainability, and economic vitality while fostering inclusive communities in dense, multifunctional urban areas. However, the relationship between TOD's economic benefits and social equity remains underexplored. This study critically evaluates TOD in Dalian, China, introducing the expanded Node-Place-Economy (NPE) model, which integrates economic and social dimensions into the traditional Node-Place model. The NPE model offers a comprehensive framework for assessing TOD effectiveness, particularly in balancing economic growth and equitable resource distribution. The research highlights significant disparities between central and peripheral regions, with central areas performing better in both economic and social equity, while peripheral areas exacerbate socio-economic inequalities. Through spatial analysis and the Coupling Coordination Index (CCI), the study identifies factors influencing the synergy between economic vitality and social equity, such as the density of commercial, sports, and entertainment facilities. The findings emphasize the need for more equitable TOD planning, suggesting that future urban developments should prioritize social inclusiveness alongside economic efficiency. This research expands the theoretical foundation of TOD and offers practical insights for urban planners aiming to achieve sustainable and inclusive urban development.
