A spatial syntactic analysis of temple cultural heritage settlements on the western Sichuan plateau of China

The protection and development of the cultural heritage of temple settlements, the utilization of cultural resources, and the inheritance of settlement characteristics are pressing issues that require urgent attention. To address these challenges, this study employs the spatial syntax research method to delve into the spatial form of the cultural heritage of temple settlements on the western Sichuan plateau. Specifically, the study focuses on four distinct settlement types in Ganzi Tibetan Autonomous Prefecture, China: Baiyu Temple, Ganzi Temple, Dongga Temple, and Gesang Temple. Using Depthmap software, the study quantifies settlement parameter values and analyzes connection value, integration degree, and comprehensibility, to reveal their syntactic structural characteristics. Our findings indicate that these four temple settlements present an organic whole in terms of spatial form. However, there are distinct differences in their syntactic structures, which are closely linked to factors such as settlement scale, historical inheritance, and other contextual influences. Based on our spatial syntax analysis, the study proposes a series of protective measures and development strategies. First, emphasis should be placed on preserving the overall spatial layout and organic integrity of temple settlements to prevent overdevelopment and the disruption of original patterns. Second, planners must strengthen the protection and management of internal spatial elements to maintain their interrelationships. Finally, planners should formulate differentiated protection and development plans tailored to the unique characteristics and values of each temple settlement type. While the study focuses on traditional settlement spatial forms and their relationship with human behavior, further exploration is needed to investigate the impact of political, economic, and environmental factors on these forms.

Topological transport of a classical droplet in a lattice of time

AbstractThouless charge pumps are quantum mechanical devices whose operation relies on topology. They provide the means for transporting quantum matter in space lattices with a single quantum precision. Contrasting space crystals that spontaneously break a continuous spatial translation symmetry and form crystals in space, time crystals have emerged as novel states of matter that organise into time lattices and spontaneously break a discrete time translation symmetry. The utility of Thouless pumps that enable topologically protected quantised transport of electrons and neutral atoms in spatial superlattices leads to the question if corresponding devices exist for time crystals. Here we show that topological pumps can be realised for time solids by transporting droplets of a liquid forward and backward in time lattices and we measure the topological index that characterises such pumping processes. By exploiting a synthetic time dimension, classical time crystals can circumvent the quantum tunnelling that underpins Thouless charge pumps. Our results establish topological pumping through time instead of space and pave the way for applications of time crystals.Key Points Periodically driven fluid droplets can be made to bounce persistently in a gravitational field and may undergo spontaneous time translation symmetry breaking forming classical time crystals. These classical time crystals can be pumped from one time site to another, and this pumping process is characterised by a topological index. Our observations establish a classical temporal counterpart to Thouless pumping of quantum particles in space lattices.

Analysis of Urban Spatial Morphology in Harbin: A Study Based on Building Characteristics and Driving Factors

With the advancement of urbanization, the complexity and diversity of urban spatial forms have become increasingly prominent, profoundly and widely affecting aspects such as urban spatial layout and planning, as well as residents’ quality of life. This paper focuses on the buildings in Harbin City, comprehensively reflecting the spatial form of Harbin through multiple dimensions including building height, volume, and area. This research precisely quantifies three key indicators of urban buildings: building coverage, building expandability, and building staggeredness. Subsequently, these indicators are intertwined with the main driving factors of urban development (including economic development and resident population) to conduct a multidimensional spatial form analysis. The results indicate that the diversity of Harbin’s urban spatial form is the result of the interplay of multiple factors, including economic and demographic influences. These analytical outcomes not only reveal the evolution mechanism of Harbin’s current urban spatial form but also provide data support and theoretical basis for future urban planning and management.

A cultural exposition model for interpreting architectural heritage: A study on Pingyao historical city

Architectural heritage, encompassing both its material and immaterial aspects, serves as a vital lens for understanding the historical, social, and esthetic values embedded in a society. As a reflection of cultural evolution, it offers insight into the architectural technologies, social structures, and collective memories of specific historical periods. This article investigates the architectural history of Pingyao historical city by employing theoretical perspectives that integrate material, social, and spiritual dimensions. The study demonstrates how the philosophy and cultural values of ancient Chinese society are reflected in the spatial and architectural forms of Pingyao. The material dimension considers how principles such as Feng Shui, numerology, and color symbolism shaped the city’s general layout and building designs. The social attribute addresses the influence of Confucianism on spatial organization, the use of culturally significant architectural elements, and the function of key structures in fostering social unity among the population. The spiritual aspect explores concepts of Eastern origin, such as Yin and Yang, the Five Elements theory, and the “Unity of Heaven and Humanity,” as these are incorporated into the city’s external architecture. Furthermore, it examines the influence of Buddhism and Daoism on Pyingyao’s architectural features. This comprehensive analysis reveals that Pingyao is far more than a collection of historic buildings; it is an intricate cultural artifact, offering a unique perspective on earlier stages of Chinese thought and society. Therefore, the preservation and study of Pingyao’s architecture offer a valuable opportunity to deepen our understanding of China’s architectural history.

The Spatial Form of the Traditional Residences of Shanxi Merchants: A Case Study of Pingyao Ancient City, China

The Shanxi merchants were one of the top ten merchant groups in Chinese history. From the Ming and Qing Dynasties to the Republic of China, they contributed significantly to the prosperity of China’s financial industry while also developing traditional residences adapted to the local living environment. Nevertheless, current research lacks a thorough investigation into how Shanxi merchant culture influenced the spatial forms of these residences. This study aimed to analyze the spatial forms of three types of Shanxi merchant residences in Pingyao Ancient City through a case study approach, exploring the factors influencing their spatial forms and their relationship with local culture. The focus is on how the shop residence, workshop residence, and courtyard residence types reflect the interplay between commercial activities and the sociocultural background through their spatial arrangements. The findings indicate a high degree of integration between commercial and residential functions, highlighting the profound impact of Shanxi merchant culture on social hierarchy and family structure. This research provides new insights into the spatial forms of Shanxi merchant residences, offering implications for the adaptive reuse of residences in modern urban planning and architectural design, as well as providing a theoretical basis and reference for the preservation and regeneration of architectural heritage.

Evaluation of spatial form and activation strategies of traditional villages using spatial information technology

Traditional villages are important carriers of regional cultural inheritance. The challenge of utilizing spatial information technology to protect and preserve the architectural spatial patterns and regional context of traditional villages has attracted significant attention. This study focuses on Biasha Miao village in Guizhou province, China, as the case study. Digital information technology was used to evaluate the architectural spatial texture and typical street space characteristics of different villages. Using the DepthMap model of space syntax and parameters such as integration, average depth value, and connectivity, the article examines the spatial form of traditional villages across three aspects: overall space, street space, and point-like public space. In the end, a spatial activation optimization strategy was proposed. The results showed that the spatial layout of buildings in different villages is closely related to the distribution characteristics of landscape elements such as landform, water system, and farmland, as well as residents’ production, lifestyle, and regional culture. Da village and Zaige new village are well-connected to the main traffic roads connecting them to the outside world, resulting in high spatial permeability and a more extroverted spatial development. Most public spaces are located near the main village road, offering good accessibility, or at the geometric center of the village, where they serve critical roles in cultural display and distribution. This study proposes targeted activation strategies focusing on road traffic, street layout, and spatial nodes to optimize and enhance the spatial quality of traditional villages, improve residents’ living environments, and provide practical guidance for the sustainable development of traditional village spaces.

Impact of green space patterns on PM2.5 levels: A local climate zone perspective

Green spaces have been demonstrated to significantly decrease PM2.5 levels. However, the impact of green spaces on PM2.5 levels in different spatial forms of urban blocks is not yet fully understood. This research utilized ensemble machine learning algorithms to investigate the impact of green space spatial patterns, assessed through landscape pattern analysis, to PM2.5 concentrations during summer and winter based on local climate zones (LCZ). The results revealed significant differences in PM2.5 concentration across the seven types of primary LCZs, primarily influenced by meteorological factors. In winter, eight green space indicators exhibited a more substantial contribution to PM2.5 levels in comparison to the summer season. Significant discrepancies were noted in the contributions of these indicators across different LCZs. Patch density (PD) and landscape shape index (LSI) made a more substantial contribution, while relative patch richness (RPR) and Shannon's evenness index (SHEI) showed a less significant contribution. The spatial pattern of green spaces was significantly related to their contributions. Among the seven predominant LCZs, the five key indicators included PD, LSI, Shannon's diversity index (SHDI), area-weighted mean patch area (AREA_AM), and connectance index (CONNECT). Spatial heterogeneity was further observed in the positive and negative contributions of each green space indicator. This study enhances understanding of the impact of green spaces on PM2.5 across LCZs and provides valuable insights for urban management and planning.

The Mechanism of Street Spatial Form on Thermal Comfort from Urban Morphology and Human-Centered Perspectives: A Study Based on Multi-Source Data

The influence of street spatial form on thermal comfort from urban morphology and human-centered perspectives has been underexplored. This study, utilizing multi-source data and focusing on urban central districts, establishes a refined index system for street spatial form and a thermal comfort prediction model based on extreme gradient boosting (XGBoost) and Shapley additive explanations (SHAP). The results reveal the following: (1) Thermal comfort levels display spatial heterogeneity, with areas of thermal discomfort concentrated in commercial zones and plaza spaces. (2) Compared to the human-centered perspective, urban morphology indicators correlate strongly with thermal comfort. (3) The key factors influencing thermal comfort, in descending order of importance, are distance from green and blue infrastructure (GBI), tree visibility factor (TVF), street aspect ratio (H/W), orientation, functional diversity indices, and sky view factor. All but the TVF negatively correlates with thermal comfort. (4) In local analyses, the primary factors affecting thermal comfort vary across streets with different heat-risk levels. In high heat-risk streets, thermal comfort is mainly influenced by distance from GBI, H/W, and orientation, whereas in low heat-risk streets, vegetation-related factors dominate. These findings provide a new methodological approach for optimizing urban thermal environments from both urban and human perspectives, offering theoretical insights for creating more comfortable cities.

Impacts of urban block form on carbon and pollutant emissions from urban life in China from the perspective of regional differences

Air pollution emissions (PE) and carbon emissions (CE) pose significant challenges to achieving the Sustainable Development Goals (SDGs) globally. The intensity of urban block development and spatial form can influence the relationship between PE and CE. This study analyzed 11,228 neighborhood samples from various climate zones across China using spatial statistics and an optimized random forest model to examine the impact of block spatial form on PE and CE. The findings reveal that: (1) The PE–CE correlation in non-first-tier city blocks in southern China is stronger than in those in northern China. The correlation is strongest in urban neighborhoods located in temperate climates. Additionally, the PE–CE correlation is weakest in Beijing and Shanghai. (2) The variation in explanatory power of different driving factors is more pronounced for CE than for PE, with PR, NDVI, and AH emerging as the most significant factors. (3) The synergy between PE and CE is strongest when BD is in the 20 %-30 % range. Similarly, the synergy is strongest when PR is in the 2–3 range. (4) BD in the 40 %-60 % range is most effective in reducing PE and CE, with 40 %-50 % range favoring CE reduction and 50 %-60 % range favoring PE reduction.

IMPLEMENTATION STRATEGY OF SUSTAINABILITY AND HIGHEST BEST USE (SHBU) APPROACH FOR FELDA LAND DEVELOPMENT

Sustainability and Highest Best Use (SHBU) approach is believed to be useful in assisting the Federal Land Development Authority (FELDA) to develop its land towards improving settlers’ prosperity and livelihood. This research aims to demonstrate a proposed strategy for implementing the SHBU using a mixed methods approach which integrates interviews and Geographical Information System-based Multiple-criteria Decision Analysis (GIS-based MCDA). The interview component seeks to obtain feedback and development aspirations from respondents in FELDA Gunung Besout 03, while GIS technology generates and displays the findings in spatial forms to empower decision-making. Data were analysed using content analysis and spatial analysis accordingly. The findings from interview shows that generally, the SHBU approach is suitable for land development. Besides, GIS-based MCDA reveals four types of future land development spanning about 796 hectares encompassing cropland, residential areas, and small business centres. The findings become the basis for crafting the implementation strategies aimed at developing FELDA land within the study area.

Evidence for a survival-driven traveling wave in a keystone boreal predator population

Cyclical population dynamics are a common phenomenon in populations worldwide, yet the spatial organization of these cycles remains poorly understood. In this study, we investigated the spatial form and timing of a population collapse from 2018 to 2022 in Canada lynx (Lynx canadensis) across the northwest boreal forest. We analyzed survival, reproduction, and dispersal data from 143 individual global positioning system (GPS) collared lynx from populations across five study sites spanning interior Alaska to determine whether lynx displayed characteristics of a population wave following a concurrent wave in snowshoe hare (Lepus americanus) abundance. Reproductive rates declined across the study sites; however, site-level reproduction declined first in our easternmost study sites, supporting the idea of a population wave. Despite a clear increase in percent of dispersing lynx, there was no evidence of directional bias in dispersal following a hare population wave. Analysis did show increasingly poor survival for lynx dispersing to the east compared to combined resident and westward dispersal. This pattern is consistent with a survival-mediated population wave in lynx as the driver of the theorized population wave. The combination of these factors supports the idea of a hierarchical response to snowshoe hare population declines with a drop in lynx reproduction followed by increased dispersal, and finally reduced survival. All of this evidence is consistent with the expected characteristics of a population undergoing a traveling wave and supports the hypothesis that lynx presence may facilitate and mirror the underlying wave patterns in snowshoe hare.

A Multivariate Model and Correlation Study on the Impact of Typical Residential Spatial Forms in the Middle Reaches of the Hanjiang River on the Thermal Environment and Thermal Comfort

Different spatial forms affect the indoor thermal environment and human thermal comfort. A good living environment largely depends on the flexibility of spatial forms, and spatial scale and proportion are the key factors affecting these forms. We selected typical residential houses in the middle reaches of the Hanjiang River in the hot summer and cold winter climate area as an example. Through on-site measurements and questionnaire surveys, we studied the impact of residential form indicators on the thermal environment and thermal comfort. We also established a multivariate model to explore the correlation among various parameters. The results showed that the spatial-real ratio of the residential spatial form index in the middle reaches of Hanjiang River was 5–58%. The height from the ground was 2.23–6.92 m. The open-space ratio was 0.04–4.55. The explanatory power of the spatial form index to indoor air temperature was 57.5%, with a strong correlation (R2 = 0.675). The explanatory power for humidity was 38.2%, with a weak correlation (R2 = 0.525). The explanatory power of SET was 30.6–50.1%, with a weak correlation (R2 = 0.466). The explanatory power of PMV was 6.5–31.7%, and PMV1.0 was weakly correlated (R2 = 0.474). The explanatory power for PPD was 15.5%, where PPD 1.0 was close to a weak correlation (R2 = 0.508). The results of this study provide reference values for the design methods of and decision-making process for green and energy-saving regional buildings.

Analysis Methods for Landscapes and Features of Traditional Villages Based on Digital Technology—The Example of Puping Village in Zhangzhou

Many traditional villages have been degraded to a certain extent due to urbanization and out-of-control management. In addition, due to the lack of recognition and continuation of spatial texture in some village conservation and planning that, in turn, resulting in the gradual disappearance of their distinctive landscape feature. Studying the spatial form of traditional villages helps preserve the authenticity of traditional villages as cultural landscape and inherits traditional historical characteristics. Using Puping Village in Zhangzhou City, Fujian Province as an example, this paper obtains the integrated information data of the village through UAV oblique photography, classifies and extracts the spatial constitution of the traditional village using digital technology, quantitatively analyses it from macroscopic to microscopic, and summarizes the spatial morphology analysis method of the traditional village. The results demonstrate that digital technology can effectively and accurately complete data collection and can provide an objective basis for zoning conservation of traditional villages based on the distinction between new and historic buildings. In addition, digital information collection on the traditional villages landscape features will prepare for the establishment of a database and comparative analysis in the future. We further suggest that digital technology analysis needs to be combined with traditional methods to have a deeper understanding of the formation process of village spatial morphology. The results of the practice in Puping Village show that the use of digital technology can provide a scientific basis for the protection and planning of traditional villages, and that this method is adaptable, which can help to efficiently collect and analyze data on landscape characteristics of other similar villages in China, and support innovative methodologies and technologies for China’s rural revitalization efforts.

Study on Urban Land Simulation under the Perspective of Local Climate Zoning—A Case Study of Guiyang City

The examination of land-use change simulations across a range of scenarios represents a pivotal research avenue for the advancement of sustainable development analysis. Nevertheless, the extant research merely categorises all building land in a land-use classification into a single category, which is unable to provide a detailed analysis of the dynamic internal spatial form of the city. This paper analyses 17 LCZ land-use types in Guiyang City in 2013 and 2022, and reclassifies them into 7 RLCZ land-use types based on the height of urban building sites. It also proposes three possible scenarios of BAU, WLC, and SPC in 2040 and simulates their land-use changes using the PLUS model. The results demonstrate that (1) the size of low-rise buildings in Guiyang has declined significantly over the past decade; (2) built-up land within cities is significantly affected by drivers such as night-time lighting, topography, elevation, and roads; (3) the SPC scenario emphasises a development pattern of land intensification and a focus on high density in urban built space. It also protects the stability of the ecosystem. The scenario can provide informative suggestions for spatial pattern changes in rapidly developing cities such as Guiyang.

Multi-granularity spatiotemporal object modelling of waterborne traffic elements

The electronic navigational charts are crucial carriers for representing the multi-source heterogeneous data of Waterborne Traffic Elements (WTEs). However, their layer-based modelling method has some shortcomings in expressing the multi-granularity features, complex relationships, and dynamic evolution of elements. This paper proposes an objectification modelling method for WTEs based on the concept of multi-granularity spatiotemporal object modelling. A classification system for waterborne traffic objects is developed based on the relevance of behavior to elements; combining characteristics of waterborne traffic, a data model for waterborne traffic objects is constructed from eight aspects: spatiotemporal reference, spatiotemporal position, spatial form, basic information, attributes, behavioral ability, structure, and associative relationships. An object extraction function is also established, extracting object attributes and relationships between objects according to different element classes. Taking the Jiashan section of the Hangzhou-Shanghai Line in Zhejiang Province as the experimental subject, the multi-granularity spatiotemporal characteristics, dynamic evolution, and relationship expression of channel class objects are tested. The experimental results show that the proposed method provides the theoretical basis and data organization mode for the multi-granularity expression of WTEs.

Microclimate analysis of Ganga riverfront in Patna: spatial form perspective

ABSTRACT The investigation in this research scrutinizes the influence of spatial form factors on thermal comfort along the Ganga riverfront trail during the spring season. Understanding how spatial form factors impact local climate parameters and PET values is crucial for optimizing thermal comfort in urban waterfronts. The research addresses the need to improve thermal comfort in rapidly urbanizing areas through strategic urban design. Data were collected from eight measurement points along the riverfront, analyzing Air Temperature (Ta), Relative Humidity (RH), Wind Velocity (v), Surface Temperature (Ts), Global Radiation (G) and Mean Radiant Temperature (Tmrt). The study employs a combination of field measurements and statistical analysis to assess the correlation between spatial form factors and thermal comfort indicators. Findings reveal that lower building height (Hb) values are associated with more favorable thermal comfort conditions, while higher Hb negatively impacts thermal comfort. The study also highlights that building spacing (ADb) influences thermal comfort, with findings contrasting those from composite climates, suggesting a need for context-specific design strategies. The research underscores the significant role of Ta and v in shaping Physiological Equivalent Temperature (PET), aligning with previous studies in diverse urban contexts. The results emphasize the critical impact of spatial form on microclimate and thermal comfort, informing urban design and planning to enhance livability along the Ganga riverfront. This study contributes to the field by providing empirical evidence and practical insights for developing thermally comfortable walking trails.

Incorporation mechanism of traditional Chinese garden elements in modern urban landscape design: an exploratory analysis based on grounded theory

ABSTRACT Following China’s reform and opening up in 1978, the image of European and American city construction has shaped China’s modern urban environment, but the creation of Chinese cities’ original intrinsic cultural landscape has been neglected. This leads to a break in the inheritance of garden culture in contemporary public and open urban landscape design. This study investigates the process of integrating traditional Chinese gardens into contemporary landscapes using grounded theory. In this study, In Vivo Coding is utilized to conduct a thorough analysis of textual materials through a three-step process: Open Coding, Axial Coding, and Selective Coding saturation test. The identified data are meticulously coded and summarized, culminating in the construction of a theoretical model. The study revealed that the incorporation of traditional Chinese garden elements in contemporary urban landscape design involves several key aspects: firstly, employing the traditional layout and spatial form of the entire design site; secondly, integrating modern public landscape design scenes with traditional garden design concepts to evoke a distinct Chinese ambiance; furthermore, utilizing both modern technology and materials alongside traditional techniques to create multi-dimensional elements within the site. The present study systematically synthesizes and examines the incorporation of traditional Chinese garden elements in contemporary urban design across six dimensions. This research offers a theoretical framework for the preservation of traditional garden culture and its integration into modern landscape, as well as furnishing mechanisms and methodologies for integrating traditional culture into contemporary landscape design practice. This research provides a valuable reference for preserving and practically implementing traditional garden elements in contemporary urban landscapes.
