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 Based on historical documents, population data, published results, remote sensing data products, statistical data, and survey data, this study reconstructed the cropland area and the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.

The effects of commercialisation on urban heritage in Tianjin: a study of citizens’ livelihood in the Five Avenues (Wudadao) historical district

This article examines the intersection of commercialisation and sustainable development within the context of urban heritage conservation and the related effects on citizens’ livelihoods, with a specific focus on the Five Avenues (hereafter referred to as Wudadao) historical district in Tianjin, China. The Wudadao district, which is known for its complex heritage architecture, historical significance, and multilayered socioeconomic context, offers significant insights through which the challenges and opportunities of urban heritage conservation and urban prosperity can be analysed.Through mixed-method research—primarily relying on qualitative interviews with local stakeholders concerning the patterns of local conservation challenges and transformations in citizens’ livelihoods, quantitative data collection on tourist motivations and frequency, and a review of conservation policy—this article aims to determine not only how to balance commercialisation with conservation efforts but also how to cocreate social value with citizens to ensure both economic vitalities and to protect historical authenticity and integrity.The findings indicate that while commercialisation brings essential funds and revitalisation to the area, overcommercialisation raises the risk of gentrification and threatens historical authenticity. This research identifies practices that strike a balance between fostering an economically vibrant district and ensuring that heritage conservation remains at the forefront of development efforts. These findings can act as a blueprint for comparable heritage locations both in China and worldwide.

Identification and Characterization of Reclaimed and Underclaimed Mine Features Using Lidar and Temporal Remote Sensing Methods within the Coastal Plain Uranium Mining Region of Texas

We developed a spatiotemporal mapping approach utilizing multiple techniques for distinguishing and mapping known reclaimed mine sites from “unreclaimed” mine sites in a historic uranium mining district along the South Texas Coastal Plains. Lidar laser scanning penetrates the vegetation canopy to expose anthropogenic modifications to the landscape. The Lidar analysis (bare earth elevation surface, slope, topographic contours, topographic textures, and overland-flow hydrography) revealed mine features. Visual interpretation of Landsat imagery and time-series analysis augmented the Lidar analysis revealing the temporal life cycle of mining. The combination of bare earth texture with time-lapse and time-series analyses revealed areas of disturbance for reclaimed mines. The spatiotemporal mapping approach proved to be most useful in identifying and characterizing the known mine pit and pile features, reclamation status, and areas of disturbance due to mining. Two mine waste volume estimation methods resulted in a 21% difference indicating that although the approach helps to map mine features and areas of mining disturbance for the purposes of mine land inventory, additional information is needed to improve the estimation of buried mine waste at reclaimed mine sites.

Towards Sustainable Development of the Old City: Design Practice of Alleyway Integration in Old City Area Based on Heritage Corridor Theory

Urbanization has increasingly led to the overlapping of old and new spaces in historic city areas, creating challenges in preserving valuable urban heritage. To meet the requirements of the effective protection, utilization, and sustainable development of these historical spaces, this study introduces a comprehensive framework grounded in the theory of heritage corridors. The proposed framework subdivides and connects fragmented historical spatial resources through the “point–line–plane” dimensions, fostering sustainability across the environmental, ecological, and cultural domains. To validate the effectiveness of the framework, we apply it to the historic city center of Wuxi. This case study demonstrates that integrating spatial resources within the old city enhances the overall quality of urban living spaces in the historic district. The findings suggest that the heritage corridor framework is a feasible and systematic approach for the sustainable renewal of historic urban areas. Furthermore, this study offers valuable insights for advancing Sustainable Development Goal 11 (SDG 11), particularly in promoting inclusive, safe, resilient, and sustainable cities.

A Study on the Influencing Factors of the Vitality of Street Corner Spaces in Historic Districts: The Case of Shanghai Bund Historic District

The revitalization of historic districts is crucial for the sustainable development of cities, with street corner spaces being a vital component of the public space in these districts. However, street corner spaces have been largely overlooked in previous research on crowd dynamics within historic districts. This study investigates the key factors influencing crowd dynamics in street corner spaces within historic districts. First, a hierarchical model of vitality-influencing factors was developed based on prior research. Potential factors influencing the vitality of street corners were quantified using multi-source data collection methods, including deep learning algorithms, and crowd vitality within these spaces was assessed through multidimensional measurements. The impact of each element on crowd vitality was then analyzed through a multivariate linear regression model. The findings revealed that eight factors—corner building historicity, first-floor functional communality, transparency, openness, density of functional facilities, greenness, functional variety of buildings, and walkability—significantly influence the vitality of corner spaces, collectively explaining 77.5% of the vitality of these spaces. These conclusions offer new perspectives and scientific evidence for the revitalization and conservation of historic districts.

Interactive contact interface elements and correlations with social behavior in historic commercial streets: a study of Qushuiting Street, Jinan

ABSTRACT As China transitions from rapid urbanization to prioritizing high-quality development, creating sociable streets has become essential. These are spaces designed to encourage interactions among people and their environment, which is crucial for the revitalization of historic districts. This study examines the relationship between “sociability” and interactive elements within historic commercial streets, focusing on identifying key “interface factors” that influence social dynamics. Jinan’s Qushuiting Street was selected as the subject of this study. Survey and behavioral mapping methods were employed to assess interactive contact interface as independent variables, including façade opening, D/H, structural shelter, plant shelter, commercial overflow, seating overflow, and social nexus points. SPSS was employed for multiple regression analysis to examine the correlations between these interface variables and the dependent variable, the sociability index. The findings indicate strong positive correlations between sociability and commercial overflow, seating overflow, and social nexus points. Additionally, plant shelter and structural shelter show a certain positive correlation with the sociability index. This research quantitatively evaluates the sociability of historic commercial streets and identifies key contributing factors, providing scientific guidelines for enhancing street vitality, increasing social interactivity, and securing effective urban and street design strategies.

Impact of Fine Water Mist Curtains on Fire Safety in Historic Buildings: A Case Study of Foshan Historical and Cultural District, Guangdong Province, China

ABSTRACT To address inadequate fire separation distances in historical buildings leading to extensive fire spread, practical research employing Fire Dynamics Simulator (FDS) was conducted. The study involved simulating a historical and cultural block in Foshan City to analyze variations in heat flux density and temperatures within a 5-meter radius of windows under fire powers of 1.5 MW, 6 MW, and 10 MW, with window openings at 10%, 25%, and 50%, respectively. The aim was to preserve the original architectural integrity without modifying existing fire separations. Augmentation of fire protection through the implementation of a fine water mist water curtain between buildings was proposed, and its efficacy in smoke and heat insulation was evaluated. Results indicate that, at 1.5 MW fire power, adjacent structures remain relatively secure with current fire separations. However, at 6 MW and 10 MW, fire spread to neighboring buildings was significant regardless of window opening area. Implementation of the water curtain with a nozzle flow coefficient (K) of 80, typical for standard coverage area sprinkler nozzles, and a spacing of 0.8 m, proved effective in enhancing smoke and heat insulation while also offering cost efficiencies. Optimal results were achieved with an average droplet size of 200 µm and nozzle pressure set at 6.0 MPa, corresponding to a nozzle flow rate of 615 L/min. These findings provide valuable insights for drafting specifications for the adaptive reuse of historical buildings and deploying fine water mist water curtains in confined spaces.
