Spatial analysis and protection of traditional villages based on spatial syntax: A case study of Linlue Village of the Dong ethnic group in Sanjiang, Guangxi
(Lodz University of Technology Press, 2023) Zhuo Xingyu; Hu Yushan; Yang Li
After a long period of accumulation of agricultural society, traditional villages have bred unique material space and cultural connotations. As a typical representative of traditional villages, Dong villages have unique geographical location and rich material and cultural characteristics, and their spatial protection and cultural inheritance have far-reaching significance and value. Affected by the current urbanization construction, traditional villages have suffered different degrees of destruction. As a representation of the social culture of the village, the protection of the material space greatly affects the development and inheritance of the village. In this paper, spatial syntax is used to quantitatively analyse the spatial morphology of Linlue Village from the aspects of village integration, connection value, control value, and comprehensibility, and summarize the characteristics of its spatial form and the internal spatial characteristics of village buildings. It is concluded that its spatial development lacks planning and capital intervention is excessive and it is necessary to balance the contradiction between social development and physical space through systematic planning from space to management. Through the analysis of the village space, the article provides a reasonable spatial optimization plan in order to better protect the material space of the village and better inherit the traditional culture.
The spatial resilience of the community’s commercial vitality: Comparative study on spatial renovation of Beijing Hutong district before and after
(Lodz University of Technology Press, 2023) Wu Jingfen; Sheng Qiang; Zeyang Xu
Based on Baidu Street View time machine and field survey data, this paper analyses the changes of community businesses before and after spatial renovation in Hutong district, which covers an area of 7 square kilometres in central Beijing from 2015 to 2020, and uses space syntax model to analyse the distribution rules and trend of changes. The results show that although the total amount of business in the community and the commercial location of each subdivision of business community have a sharp fluctuation, in essence, the location of commercial agglomeration and distribution in the community is very stable before and after renovation, and has a high correlation with the standardized Angle choice parameter of 1000m radius. In addition, after renovation, the correlation between community commercial distribution and population density, urban commercial density, public transportation convenience and other three parameters is improved, reflecting the spatial resilience brought by spatial connection behind the functional change.
Research on Quantitative Evaluation and Influencing Factors of the Vitality of Newsstand – an example of Beijing
(Lodz University of Technology Press, 2023) Wu Jingfen; Sheng Qiang; Li Xinyi
Newspaper kiosks used to be cultural Windows of cities, but in the data era, they face many challenges of survival and problems of future renewal. At the micro level, this study obtained the total number of transactions of 25 existing kiosks and the number of transactions of each derivative function through field research and carried out a quantitative evaluation on the vitality of kiosks based on this. The paper further analyses the explanatory power of five parameters, including population density, commercial function, topological form, geometric form and street walkability, on the vitality of the existing newsstands. At the macro level, based on Baidu Street View time machine, this study obtained the spatiotemporal differentiation data of 277 newsstands in the western part of Beijing which covers an area of about 160 square kilometres (2013–2021) and compared the difference of the above five parameters of the death and the existing newsstand space in an eight-year time span. In this way, we can reveal the reasons that affect the vitality of the newsstand for a long time. It is found that the walkability and population density are the main factors affecting the vitality of newsstands, both in the existing newsstands and the newsstands within a period of eight years. In terms of each function, the correlation between the number of transactions of newspapers and periodicals and the number of transactions of life and retail functions and the two parameters of walkability and commercial function density are different. On this basis, the paper puts forward some strategies, such as function updating and space positioning updating, in order to provide reference for the demolition, construction and urban renewal of the newsstand in the future.
Spatial Resilience of Local Places: A comparative study on Beijing’s breakfast service before and after Covid-19
(Lodz University of Technology Press, 2023) Wu Jingfen; Sheng Qiang
The distribution of breakfast services under the impact of COVID-19 provides an ideal case for studying the supporting role of urban space on self-organized commerce. Based on the large-scale, multi-type and high-precision field survey of breakfast services in the central urban area of Beijing in 2019 and 2020, this paper analyzes the distribution pattern of breakfast services by using topological spatial accessibility based on spatial syntax, combined with the work-housing and commuting density data obtained by mobile signaling. Statistics showed that after the epidemic, the total amount of breakfast decreased and the distribution imbalance was further aggravated but the location of the gathering center was stable. Breakfast services on high topological accessibility streets are more likely to survive. Regression analysis showed that residential density had a greater effect than working density except for breakfast in the supermarket. Streets with high topological accessibility and close to subway stations have a stable supporting effect on the survival of breakfast services.
Spatial-temporal Changes and Driving Forces of Nanning San Jie Liang Xiang from 1947 to 2020
(Lodz University of Technology Press, 2023) Wei Hanyu; Chen Jiaxin; Wang Guoguang
The urban space remains and traditional cultures face the contradiction between development and conservation. In urban morphology study, GIS and Spatial Syntax enables quantitative analysis of morphology evolution and explorations of the driving forces through which could control the change of the urban form. This paper is about one case study of San Jie Liang Xiang, Nanning, China. Firstly, four critical periods are defined. And the morphological characteristics and structural relationships of street blocks in each period are extracted. Secondly, space syntax is used to study the morphological evolution in terms of its spatial configuration and the relationship between spatial characteristics and urban development. Third, the morphological evolution and evolution dynamics are matched to explain the law of spatial-temporal change. Finally, this paper attempts to establish spatial form element control to guide the practice, combining form type with form design. In conclusion, the driving forces affect the morphology in the development period. Following the law of morphological evolution, morphological guidance and control based on driving forces research may provide solutions for renewing sustainable historical street blocks.
Retain or Rebuild: Different Pathways of Redevelopment in Urbanising Chinese Villages
(Lodz University of Technology Press, 2023) Utzig Lukas; Vaughan Laura; Misselwitz Philipp
While the ongoing rapid urbanisation in China transforms farmland into urban areas, old villages receive a certain level of protection from being completely rebuilt. This is due to the grassroots ownership of rural land, which is held by village collectives. The village becomes surrounded by the city, called chengzhongcun. During this intense transformation from an agricultural to a landless way of life, the village collectives redevelop their dense settlement in very different ways to create resilience and benefit from the opportunities that urbanisation brings. This research is examining four old villages in the Huangyan-Taizhou region during their redevelopment. It will be analysed how different stakeholder decisions create variations in their urban form and how this influences their economic resilience. Employing methods from the space syntax framework coupled with land use mapping and interviews, this research builds on Hillier’s concept of the movement economy. Hillier finds that urban form generates movement, which then becomes the precursor for street-based economic activities such as retail and services. This relates to Vaughan’s and Hall’s work on ethnic marketplaces which identifies informal economic networks as key social safety nets of low-income and migrant neighbourhoods. The findings suggest that villages that have seen bottom-up incremental changes and retained their organic street network generate higher movement than rebuilt villages and thus are able to shift their economies towards the service sector. Their building stock is also more adaptable to ground-floor subdivisions and retail use, while redeveloped villages often have set-back buildings with residential ground floors that cannot facilitate informal use or retail space. Since the former farmland surrounding the villages is developed into industrial land, the villages are the only possible site for restaurants, shops and other amenities, creating many opportunities for villagers. They can be however only realised with specific pathways of redevelopment.
Urban segregation of London social housing estates: Measuring access to the city and the question of regeneration
(Lodz University of Technology Press, 2023) Utzig Lukas; Karimi Kayvan
While London is currently experiencing an acute shortage in affordable housing, local authorities are selling existing council estates for private redevelopment. This practice is often explained with the notion of failure of certain buildings, such as the Robin Hood gardens estate which went on to be partly demolished in 2017. At the same time increasing evidence has been gathered, which shows that social, walkable streets and neighbourhood amenities are especially important to economically vulnerable groups as they provide the basis for local communities that act as social support networks through childcare, informal employment, or housing. However, it is often these groups that are most affected by segregation through the urban form of the neighbourhood and limited access to the wider city. Research into segregated communities by Legeby, among others, suggests that a simple regeneration of the buildings themselves does not tackle the underlying problem of social urban resource distribution. This research will investigate the relation of urban form to the potential of pedestrian activity and distribution of neighbourhood resources for four high-rise council housing estates in London. An innovative workflow combines space syntax measures with Gravity accessibility, including the access to amenities such as shops and restaurants via the street network. The findings suggest that access to the resources the city provides, including access to urban co-presence, is very unequally distributed between the four case studies. It is also shown to what degree some urban form is creating obstacles and how it can be measured and compared. Improving opportunities through urban form in the neighbourhood may be an alternative to demolition of the buildings. Quantifying these inequalities offers a more nuanced debate about social housing redevelopment and a pathway for sustainable improvement.
Development of new indexes of the ‘Generic City’ in the Baltic coastal city network
(Lodz University of Technology Press, 2023) Gloaguen Thomas; Zaleckis Kęstutis; Gadal Sébastien
The concept of ‘Generic City’ is used in space syntax to model the levels of functioning of cities – interactions, flows, impacts of spatial, urban, and territorial structures and organisations. The traditionally associated indexes of ‘Choice’ and ‘Integration’ provide additional possibilities for comparison and classification of urban structures in a context where public policymaking requires more knowledge about cities in terms of connectivity, centrality, accessibility, etc. In this article, we extend the application of the ‘Generic City’ concept, originally designed for cities, to the coastal regions of the Baltic countries –Estonia, Latvia, and Lithuania. New indexes are being experimented to highlight ‘foreground’ and ‘background’ networksand better reflect the local peculiarities of Baltic urban structures, whose evolution is dependent on political and economicfactors of the last decades. Their robustness is tested by Spearman and Pearson's correlations with human activity data.The results show that for a limited radius of 1 km, the ‘Betweenness’ and ‘Length’ indexes perform best in describingthe ‘background’ network. For an unlimited radius, the correlations with the ‘Network Quantity Penalized by Distance’ indexare robust to validate the ‘foreground’ network model. The results highlight the need to normalise the indexes to comparenetworks of different sizes.
