“…Following the establishment of a shaft model in ArcGIS, a comprehensive analysis was conducted by Depthmap. The spatial patterns of various ethnic villages were extracted using four quantitative indexes [42][43][44][45]: global integration, local integration, connection, and intelligibility values, establishing a comprehensive framework for comprehending the relationships between elements. The integration evaluates spatial centrality via global and local values; the connection values reflect spatial connectivity, emphasizing how spatial elements link; and the intelligibility values reveal the collective impact of spatial arrangements.…”

Analysis of spatial patterns and driving factors of different ethnic villages under regional integration is important for the conservation and development of ethnic villages. This article takes seven multi-ethnic villages in the Dadu River Basin of Ganzi Prefecture as an example; we employ a quantitative model of spatial syntax based on the theory of figure–ground relationship to link the tangible and intangible spaces. The results reveal the logical context and formation mechanism among the overall layout, residential architecture, and public space of the villages. The findings of this study are as follows: (1) The site of different ethnic villages reflects commonality. (2) The spatial configurations of the villages are significantly influenced by the surrounding natural environment, with significant differences. Cluster-concentrated villages exhibit the smallest expansion trend, rich spatial levels, and strong ethnic territoriality; strip-intensive villages have the largest scale and the strongest permeability; and radiation-dispersion villages have variable expansion directions and architectural relationships among residents. (3) Both of the participants’ selection behaviors and residential spaces constitute the internal structure for the ethnic culture, which is driven by the humanistic spirit and force of social order, making the spatial morphology a diversified and multi-layered characteristic. (4) The rural space has gradually changed from a single residential unit to a complex unit with multiple functions. The findings extend the scope of research to ethnic villages in watersheds and provide a theoretical and practical basis for the development of other similar rural villages.

This article aims to investigate the complex relationship between a local population and its natural and urban environment. The study area, which was previously dominated by cereal cultivation, is currently facing profitability challenges due to climate change, water scarcity, rapid urban expansion, and the overexploitation of aquifers, influenced by changes in agricultural practices, which are disrupting the local ecosystem. This study relies on three interconnected indicators, population growth, climate change effects on agriculture, and the NDVI (Normalized Difference Vegetation Index), and reveals the impact of these factors on agricultural practices. Google Earth Engine was employed to determine the urbanization and greenness indices using scripts. The significant findings of this study demonstrate the remarkable demographic growth of 49.96% during the study period (2000–2020). Furthermore, this growth has led to a new trend towards intensive farming, with a substantial increase in irrigated lands by 44.19% and a multiplication of protected crop lands by 20 times, rising from 19.88 to 405.89 hectares. Additionally, horticultural production surged by 212.4% during the same period. Moreover, groundwater levels shifted from less than 50 m in the northern regions to less than 150 and 300 m in the southern part of the study area. The water potential in the study zone cannot meet the demands of the new agricultural orientation, which tends to deplete local groundwater, potentially causing recurrent shortages of agricultural products. This study underscores the importance of incorporating agricultural production into future urban planning and development programs to maintain a renewed balance between built environments and agriculture in peri-urban areas.

“…If the global connectivity is highly positively correlated with the integration degree, it indicates that the spatial system is better understood; in contrast, when the information obtained through the local space easily misleads pedestrians, this reflects the poor comprehensibility of the spatial system. In terms of urban spatial planning, the comprehensibility can effectively identify urban historical core areas and new areas [44] and can be used as an evaluation index of urban pedestrian space quality, which can help to improve the spatial walking experience in pedestrian-friendly cities [45]. In commercial building space research, some scholars have used comprehensibility to analyse the spatial recognition of shopping centres, optimise visitors' walking experience, and effectively improve the defects of a poor commercial building atmosphere [36].…”

Designing reasonable commercial transportation space is of great significance to enhancing the overall value of commerce. This study takes the classic cases of three typical plans of commercial wholesale centres (CWCs) as the research object, uses space syntax to analyse the connectivity of the architecture of the traffic space, simulates the current situation of the pedestrian flow distribution through ArcGIS, and constructs a multiple regression model for the association between connectivity and pedestrian flow distribution. The results of this study show that for CWCs with a single business type and a focus on traffic efficiency, the distribution of the pedestrian flow is most affected by the main entrance and the vertical traffic distribution. For different types of planes, when the commercial traffic space has strong symmetry, its group relationship is more concise. While a uniform form is more conducive to achieving a balanced distribution of commercial traffic, the asymmetry of the plan layout helps to establish a psycho-spatial map for the visitors. In addition, the commercial value of the first floor is greatly influenced by the layout of the building entrance, and the commercial value of the second floor is greatly influenced by the location of the vertical transportation. In conclusion, when commercial building development planning is in the stage of traffic flow design, the use of space connectivity traffic data can assist in the selection of construction plans and predict the distribution of the economic value in CWCs.
