Revitalizing Heritage: The Role of Urban Morphology in Creating Public Value in China’s Historic Districts

In the context of historical districts becoming a key to the urban transformation and high-quality development of Chinese cities, this paper investigates the regeneration of historic environments in China, emphasizing the creation of public value through urban morphology. By analyzing five distinct case studies—Chengdu KuanZhai Alley, Shanghai TianZiFang Alley, Guangzhou EnNing Road, Taiyuan ZhongLou Street, and Beijing NanLuoGu Alley—this study explores the relationship between urban form and public value creation from 2000 to 2020. The research posits that the spatial attribute of “public nature” is central to the regeneration process, highlighting the importance of understanding how urban spaces can foster community engagement and social interaction. An evaluation system is constructed to assess the regeneration of historic areas based on spatial “publicness” and people’s perceptions, addressing the need for a more nuanced approach to urban planning. The findings reveal that effective urban regeneration not only preserves historical significance but also enhances the quality of public spaces, thereby contributing to social equity and cultural integrity. This study aims to provide valuable insights for urban planners and policymakers, advocating for a public value-oriented approach to the renewal of historic districts that balances economic development with the preservation of cultural heritage. The integration of public value concepts into heritage management is crucial for creating vibrant urban environments that resonate with community needs and aspirations.

Enhancing authenticity in historic districts via soundscape design

AbstractHistoric districts play an important role in urban planning and protection. While previous research on soundscapes has focused on acoustic comfort or preferences in these districts, the aspect of authenticity has been somewhat overlooked. Therefore, this study proposes a methodology for constructing soundscapes that enhance the authenticity of such districts. Using the grounded theory approach, we identified four key components for enhancing authenticity via soundscapes: the aim of soundscape design, physical and cultural characteristics of soundscapes, the effects of soundscapes, and the influence of spatial characteristics on soundscapes. A theoretical framework was developed to illustrate the enhancement of authenticity in historic districts via soundscapes. To verify the applicability and advancement of the proposed framework, it was compared with methodologies and steps obtained from previous soundscape research in historic districts. This study underscores the significance of soundscape design in creating authenticity in historic districts, thereby contributing to the development of soundscape design in historic districts and offering sustainable solutions for the protection and renewal of urban cultural heritage.

Understanding community perspective on the heritage of locality: memory map methodology

PurposeCommunity involvement in heritage preservation requires appropriate approaches. Sanciai (in Lithuanian: Šanciai) historic district in Kaunas (Lithuania) has long-lasting military and industrial heritage, valuable urban structure and connections to the natural frame of the city. Sanciai residents’ willingness to participate in heritage preservation and urban planning prompted the aim of this research – to develop, test and present the mapping methodology, that would be applicable in the process of community involvement into heritage identification, preservation, interpretation and creation process.Design/methodology/approachThe methods of research included analysis of literature and theoretical research, development and testing of the methodology for the community involvement in heritage identification, preservation, interpretation and creation process. The workshop methodology and interactive online map are presented in this research. The memory map methodology developed and presented in this research includes the elements of mental mapping, design thinking and citizen science.FindingsThe methodology was tested in spring of 2021 in two-day online workshops with the students of pro-gymnasium located in Sanciai. Workshop participants together with workshop coordinator and moderators created different layers of the mental map, collected stories from the members of community and gathered the data for online interactive Sanciai memory map. The evaluation of the methodology and workshop results allowed concluding that memory map methodology is a functioning participant, community and research-oriented approach that can be applied in diverse heritage and community related circumstances.Originality/valueThe originality of the research is determined by the synergistic nature of developed memory map methodology which complements traditional mental mapping with creative hands-on techniques, empathy-oriented tasks and interactive online tool. Moreover, the research reveals the importance of local-global connections in urban studies as active local community became the stimulus for memory map methodology. The two-fold aim of the methodology – community cohesion and empowerment as well as research data collection – contributes to the originality of the research as well.

A Scene Graph Generation Method for Historical District Street-view Imagery: A Case Study in Beijing, China

From traditional to digital contexts: new characteristics of the public’s spatial perception of urban streets in the age of technology

The constant development of internet technology in the digital age has changed the way people interact with space. To explore whether and what changes have occurred in the public’s spatial perception of the street during the shift from the traditional to the digital age, this paper compares the public’s spatial perception characteristics in the two contexts through a classical theory review and empirical coding analysis with the Xiaolouxiang historic district as an empirical case. The frameworks of public spatial perception characteristics are similar in both contexts, with a focus on the three dimensions of objects, buildings and spaces, and activities. However, compared with that in the traditional context, the public’s spatial perception of the street in the digital context of Xiaolouxiang has undergone new changes in three aspects: from focusing on the three-dimensional experience of space to focusing on the two-dimensional visual aesthetics of space, from emphasizing spatial totality to focusing on spatial details, and from focusing on the use of space to emphasizing the cultural characteristics of space. Research emphasizes that, within the context of digitalization, spatial design should place greater emphasis on visual aesthetics, detail processing, and cultural expression to better meet the needs and expectations of the public. This work identifies new features of the public’s perception of urban street space in the context of digitalization and accordingly provides suggestions for the future design of urban street space. The findings of this study not only enrich the foundational research content of spatial perception theory but also offer new perspectives for designers and planners in the practice of urban block renovation.

The Formation and Preservation of Urban Heritage Through Urban Landscape Transformation: A Case Study of Pittsburgh

This study examines the potential of urban landscape transformation to generate and develop new heritage and the role of heritage urbanism in an industrial city. It explores whether the changeover of urban heritage districts in Pittsburgh (PA, USA) can give rise to a novel type of urban heritage. Pittsburgh experienced urban development primarily driven by the presence and accessibility of natural resources, rather than favorable geographical conditions: topography characterized by rugged hills, rock formations, rivers, and stream valleys. The integration of the American-style grid within this unique natural environment resulted in intriguing juxtapositions. Consequently, elements such as bridges, viaducts, stairs, tunnels, and historical inclines gained paramount importance in shaping the urban fabric. The city’s remaining preserved or transformed urban heritage is protected through historic districts designated by the Department of City Planning, which enforces specific planning and design guidelines. The study employs a multi-faceted approach combining the concepts of historic stratification (urban palimpsest), integrated urban morphology, space syntax (integration analysis), and heritage urbanism. During the personally conducted long-term fieldwork, the selected case studies described herein (historic districts, university campus, and traditional neighborhood) proved to be the most suitable for demonstrating urban heritage formation through urban landscape transformation.

A 28-time-point cropland area change dataset in Northeast China from 1000 to 2020

Abstract. Based on historical documents, population data, published results, remote sensing data products, statistical data, and survey data, this study reconstructed the cropland area and the spatial pattern changes at 28 time points from 1000 to 2020 in Northeast China. The period from 1000 to 1600 corresponds to historical provincial-level administrative districts, while the period from 1700 to 2020 corresponds to modern county-level administrative districts. The main findings are as follows: (1) the cropland in Northeast China exhibited phase changes of expansion–reduction–expansion over the past millennium. (2) The cropland area in Northeast China increased from 0.55×104 km2 in 1000 to 37.90×104 km2 in 2020, and the average cropland fraction increased from 0.37 % to 26.27 %; (3) from 1000 to 1200, the cropland area exhibited an increasing trend, which peaked in 1200. The scope of land reclamation was comparable to modern times, but the overall cropland fraction remained low. The cropland area significantly decreased between 1300 and 1600, with the main land reclamation area being reduced southward into Liaoning province. From 1700 to 1850, the cropland area increased slowly and the agricultural reclamation gradually expanded northward. After 1850, there was almost exponential growth, with the cropland area continuously expanding to the whole study area, and this growth trend persists until 2020; (4) the dataset of changes in the cropland of administrative districts in Northeast China, reconstructed based on multiple data sources and improved historical cropland reconstruction methods, significantly enhances time resolution and reliability. Additionally, the dataset shows relatively better credibility assessment results, which can provide a refined database for historical land use and land cover change (LUCC) dataset reconstruction, carbon emission estimation, climate data construction, etc. The dataset can be downloaded from https://doi.org/10.6084/m9.figshare.25450468.v2 (Jia et al., 2024).

Defining indicators for evaluating the residential environment in historic districts based on human needs: focusing on two cases in Northern China

ABSTRACT Compared to traditional communities, the residential environment in historic districts (HDs) is generally poor. Tourism development within HDs has affected these environments. As tailored assessment indicators are absent in HDs, this study introduces the historic district residential environment assessment indicator (HD-REAI) – a framework designed for the urban setting of HDs. The HD-REAI integrates Maslow’s theory and addresses the challenges and attributes of HDs. HD-REAI focuses on factors like housing property rights and district culture, which are pivotal for HDs. This enables a more nuanced and relevant evaluation of the residential environment in these areas. This study details the development of the HD-REAI and validates its efficacy through its application in two Northern Chinese HDs. The results demonstrate that the HD-REAI effectively assesses the environment, offering a specialized and context-sensitive tool. Moreover, different socioeconomic attributes have different effects on the assessment results. This study could provide a basis for constructing more refined and context-specific assessment tools to enhance residential environments in HDs

Analysis of Multi-Dimensional Layers in Historic Districts Based on Theory of the Historic Urban Landscape: Taking Shenyang Fangcheng as an Example

The accelerated process of urbanisation in China is resulting in a decline in and threat to the historic landscape of historic districts. This study is based on the theory of historic urban landscapes and employs a multi-dimensional layers research framework for historic districts. It adopts a single case study and a research method that combines quantitative and qualitative methods. The stratification elements of Fangcheng in Shenyang are identified and summarised, the process of stratification is analysed, and the stratification patterns and laws are summarised through the acquisition and collection of multivariate data. The findings of this study indicate that the stratification elements of the Fangcheng Historic District have undergone five distinct phases of stratification evolution. The resulting stratification pattern can be summarised as follows: newborn, preserve, override, juxtaposition and decession. The spatial elements are layered in the following pattern: The historic landscape can be conceptualised as comprising four layers: (1) the layering of the historic landscape with large public buildings as the anchor point; (2) the layering of the historic landscape with the spatial pattern as the skeleton; (3) the layering of the historic landscape with the iconic buildings as the nodes; and (4) the layering of the historic landscape with the correlative elements as the substrate. The law of value element layering primarily reflects the principles of concentration, diversity and adaptation. In light of the urban historic landscape theory, the reconstruction and restoration strategies, integration of old and new and adaptive conservation of historic landscapes are proposed to offer novel insights and guidance for the conservation of the historic landscape in the Fangcheng Historic District.

Assessing the Cascading Post-Earthquake Fire-Risk Scenario in Urban Centres

The frequency of urban fires has grown in recent years everywhere, especially in historic districts, including in Portugal, due to the existence of sensitive igniting materials, the proximity of buildings, the complex urban layout, and the presence of many people. The current study proposes a technique, applied in the Baixa Pombalina (downtown) area in Lisbon, to undertake an appropriate evaluation of the post-earthquake fire cascading effect, which may cause major damage. The earthquake vulnerability and damage scenario were carried out using the Risk-UE method. An empirical fire ignition model was then applied to determine the quantity and location of fire ignitions for different return periods. Furthermore, the simple fire spread Hamada’s model was applied to both the equally spaced grid buildings, as in the original Hamada procedure, and the current study area layout for different time thresholds. Finally, the risk assessment for both models was carried out, allowing for the estimation of earthquake and fire losses, respectively. The results demonstrated that the models are comparable, showing that the Hamada model might be a useful tool for large-scale evaluations aimed at disaster-risk reduction and management since it gives useful information for managing and reducing natural and anthropogenic hazards.

Participatory Renewal of Historic Districts Based on Bayesian Network

Public participation is a requirement for contemporary urban governance in China, especially in the protection planning of historic districts. In the rapid development stage, many historic districts have lost their functional positioning in cities and are gradually disappearing due to outdated facilities and services. Previous studies have pointed out that protecting historic and cultural districts requires the joint efforts of multiple stakeholders. Integrating multiple stakeholders’ interests and needs is a complex problem in related research fields and planning practices. The traditional forms of public participation, such as questionnaire surveys, interviews, and symposiums, have the problem of high time costs for collection and analysis. At the same time, the information has been translated multiple times, making it challenging to avoid misunderstandings and errors. Therefore, there is an urgent need for an alternative platform for public participation in the renewal of China’s historic districts. Taking Houzaimen Street in Jinan City as an example, this paper uses the Bayesian network to establish a spatial evaluation model of historic districts. Our aims are to translate natural semantics into the design semantics of the architectural field, accurately locate the spatial problems of the historic district, and provide targeted improvement measures. In this paper, a public feedback channel for Houzaimen Street is established to provide a reference for the renewal of the historic district and the advancement of public participation.

Historic street layout and its impact on shaping residents’ daily lives: insights from Sanxue Street, Xi’an

ABSTRACT Historic street layouts are integral to historic districts’ tangible cultural heritage and are intricately linked to the residents’ daily lives; however, existing studies have only examined their spatial aspects, primarily using quantitative methods. Conversely, studies on tangible cultural heritage’s impact on residents’ lives have principally employed qualitative methods. Therefore, this study bridges qualitative and quantitative approaches to propose a layout – daily life model, which explains the relationship between the layout of Xi’an, China’s Sanxue Street historic and cultural district, and its residents’ daily lives. A combination of space syntax and geographic information system-based land-use analyses revealed that eating, shopping, calligraphy, and transportation were the main activities of residents. Questionnaire responses from 335 participants validated the proposed model and confirmed its feasibility. When certain types of facilities are widely distributed in streets with high choice and integration, residents’ daily lives tend to involve the functions represented by them. Furthermore, calligraphy is an important part of most residents’ daily lives, regardless of the transportation mode used. This study contributes to the understanding of the effect of tangible cultural heritage, particularly street layouts, on residents’ daily lives in historic districts.

Examining urban design strategies in historic districts: a systematic literature review

The global community faces the challenge of balancing the conservation of historic districts with urbanisation demands. This systematic literature review explores innovative strategies for conserving and revitalising historic districts within urban design. An analysis of literature from the Scopus database highlights this as a prominent research area, supported by international reviews emphasising the critical role of urban design strategies. The findings indicate that urban designers can utilise modern geographic information technology, spatial analysis, data support, community engagement, and transdisciplinary knowledge to regenerate historic districts effectively. However, there is a notable lack of systematic, in-depth empirical research, with a predominance of conservative and repetitive descriptive case studies. Although these studies logically explore the significance of historic districts, there is an urgent need for innovative research on urban design methodologies. This study aims to identify research gaps through a comparative analysis of international findings, offering new perspectives and theoretical support for the sustainable development of historic districts.

MANAGEMENT OF EMERGENCY MEASURES PROJECT OF ALGIERS’S KASBAH

Management strategies for the conservation and safeguarding of cultural heritage in general, and urban heritage in particular, have evolved greatly over the past two decades. The relationship between heritage and development is now omnipresent in the policies of construction or reconstruction of territories, where the major challenges lie in their enhancement. Algeria does not have a great deal of experience in the management and administration of heritage safeguarding and enhancement projects, whether urban or architectural, as evidenced by the significant number of projects that remain unfinished or incomplete due to a lack of efficiency. Within the framework of the Permanent Plan for the Safeguarding and Enhancement of the Protected Historic District (PPSMVSS) for the protected historic city of Algiers, emergency projects have been launched to slow down or even stop the deterioration of this heritage site. The objective of this study is to understand the process of formalizing and managing projects in protected historic districts, as well as the interactions between the different stakeholders involved.The methodology used combines on-site surveys, interviews, and questionnaires with the various stakeholders. It refers to the conceptual model of project success factors developed by Pinto and Slevin, in order to evaluate these operations, which have not led to theexpected results.

Research on the impact of traditional soundscapes on physiology and subjective restoration in historical and cultural districts

A healthy urban sound environment is the common pursuit of both residents and urban designers. The restorative effects of natural soundscape on physiology and psychology have been proved. However, the potential health benefits of the historical and cultural attributes of soundscapes are yet to be explored. This study took the traditional sound sources and environments in the historical and cultural district as the research object, and presented the audio-visual scenarios in the laboratory. Finally, 7 physiological indicators and subjective evaluation of perceived recovery soundscape scale (PRSS) of 37 subjects were assessed. The results indicate that historical soundscapes have an impact on subjective restorative factors such as Fascination and Being-Away. However, there is no significant influence on all physiological indicators. This suggest that the historical and cultural attributes of soundscapes might have a positive effect on psychological restoration, but the impact on physiology is not significant.

Exploring residents’ expectations and designers’ perspectives towards post-earthquake permanent housing: A case study in Antakya

Post-disaster permanent housing is the backbone of the recovery efforts after destructive events. It holds great potential to adopt new technological innovations and to provide improved conditions for these everyday spaces. However, previous investigations suggest that these housing projects lack consideration of the inhabitants' expectations, needs, and values due to environmental, cultural, and social factors, resulting in a dissatisfactory built environment. Following the Kahramanmaraş earthquake on February 6, 2023, this research aims to explore the expectations of affected residents in the historic district of Antakya. We expect to contribute to decision-makers, designers, and the technology industry to develop more user-centered housing recovery efforts in the aftermath of these devastating events. The findings revealed four implications from the expectations for post-earthquake homes: (1) designing for togetherness, (2) valuing community efforts and traditional work, (3) including productional activities, and lastly, (4) preserving and reminiscing heritage values. Additionally, we discussed these four implications with multi-disciplinary designers to expand the discussion space for designing post-earthquake permanent homes in Antakya. Overall, these implications suggest some future architectural changes in homes as their residents' expectations, including the creation of new heritage and production spaces using digital, physical, and mixed reality technologies, as well as the emergence of new social gathering spaces. By conducting a case study in Antakya, our research highlights the potential for the further development of post-disaster permanent homes that not only provide shelter and safety but also enhance the overall quality of life for the residents, both for Antakya and the other relevant cases worldwide.

Research on Thermal Comfort Evaluation and Optimization of Green Space in Beijing Dashilar Historic District

Global warming and urban heat island effects negatively impact the development of urban thermal environments, making them very uncomfortable to live in. Green space plays an essential role in controlling and improving air pollution, regulating the microclimate, and enforcing compliance with public health requirements. Therefore, this study explored the relationship between green space and thermal comfort in the historical neighborhood of Dazhalan in Beijing through questionnaires, observational interviews, and numerical simulations. The current situation of the microclimate environment in the green space of the block was observed first. Then, the microclimate environment was simulated by the ENVI-met 5.6 software. The thermal comfort of the three types of space, such as enclosed space, strip space, and corner space, was also evaluated to explore the coupling relationship between different green space elements and microclimate evaluation factors. It was found that the thermal comfort PET had a positive correlation with the sky openness SVF. The green space morphology was quantitatively measured, and it was found that the thermal comfort PET had a negative correlation with the three-dimensional green quantity of green space. The paper developed managing strategies for optimizing the layout and construction mode of the green space. The ultimate goal was to rationally match the greening planting, improve the pavement of the underlying surface of the block, and optimize the design of the internal space topography.
