Evaluating the effects of built environment factors (BEF) on residential land carbon emissions (RLCE) is an effective way to reduce RLCE and promote low-carbon development from the perspective of urban planning. In this study, the Grey correlation analysis method and Universal global optimization method were proposed to explore the effects of BEF on RLCE using advanced metering infrastructure (AMI) data in Zibo, a representative resource-based city in China. The results indicated that RLCE can be significantly affected by BEF such as intensity, density, morphology, and land. The morphology is the most critical BEF in reducing RLCE. Among them, the building height (BH) and building shape coefficient (BSC) had positive effects on RLCE, while the high-rise buildings ratio (HRBR) and RLCE decreased first and then increased. The R² of BH, BSC, and HRBR are 0.684, 0.754, and 0.699. The land had limited effects in reducing RLCE, and the R² of the land construction time (LCT) is only 0.075, which has the least effect on RLCE. The results suggest that urban design based on BEF optimization would be effective in reducing the RLCE.

Rural revolutionary heritage in China represents a distinctive form of vernacular heritage. It holds significance not only for its connection to historical events and prominent figures, but also encapsulates the distinctive features of vernacular architecture. Since 2020, the present authors have conducted a survey of the rural revolutionary heritage in Jinan. The findings indicate that common challenges in this context are the issues of overprotection and low utilization efficiency. The two former command posts of the Jinan Campaign are representative of rural revolutionary heritage. The Yinjiadian command post building received the designation of revolutionary heritage earlier than the one located in Tangjiagou Village. However, it has undergone inappropriate repairs and alterations over time, which have compromised its original integrity. The Tangjiagou command post was granted heritage status towards the end of 2020, but despite retaining its vernacular architectural structure, material, and form, it has not been effectively conserved and utilized. In the present study, the history, characteristics, and current situation of the two command posts of the Jinan Campaign were explored using various methods such as historical data collection and analysis, field investigations, oral interviews, GIS analysis, and comparative research. The aim of the study was to determine regeneration strategies for the two command posts of the Jinan Campaign by identifying and comparing their character-defining elements. A comparative investigation of the two command posts in the Jinan Campaign was conducted and based on their different heritage characteristics and preservation status, regeneration strategies were proposed. Additionally, a systematic regeneration strategy for rural revolutionary heritage was explored, considering the unique challenges and opportunities associated with preserving and revitalizing these historic sites. Such measures promote the activation and survival of China’s rural revolutionary heritage while providing valuable reference for its protection and research.

In the process of urbanization, peri-urbanization is a unique phenomenon in China. For residents living in peri-urbanization areas, realizing the balance between workplace and living space is not only a crucial guarantee for them to secure livelihood but also an important criterion to measure the quality of China’s urbanization. Based on the questionnaire data distributed by the research group in Zoucheng County, China, in 2021, this study measures the degree of jobs-housing balance in county area by constructing the benefit index of jobs-housing balance and explores factors affecting the jobs-housing balance in county area by using logistic regression, random forest classification, and regression tree. Results: Firstly, with 57% of the residents have achieved the standard, the level of jobs-housing balance in Zoucheng County is relatively high. Secondly, individual, household and built environment dimensions jointly affect jobs-housing balance of residents. Furthermore, at the current stage of China’s county areas, household is not the core dimension influencing jobs-housing balance. Thirdly, factors that passed the significance test can be divided into three categories: key factors, important factors, and auxiliary factors. Occupation type, commuting way and residential location are the key factors affecting the jobs-housing balance, which deserve our attention. Therefore, according to the above conclusions, relevant suggestions for promoting jobs-housing balance of residents in county area were put forward. For instance, considering the diverse occupation of local residents, employments that match their skills should be offered, and as for peri-urbanization areas, the regulatory of jobs-housing balance should be placed in urban and rural areas.

Decades ago, bicycles used to play an important role in urban transportation in Chinese cities, but they have been gradually replaced by private cars, metro, buses, and some other modes, owning to the fast-growing mobility demand as a result of urban expansion and motorization. However, in recent years, with the development of Information and Communication Technologies (ICT) and the initiative of the sharing economy, bike-sharing systems (BSSs) have been implemented extensively in Chinese cities. Their usage patterns can be revealed via system-generated data, yet less is known about users’ attitudes towards and preferences for these systems. In this study, we draw on two surveys conducted in Guangzhou and Beijing on the perceptions of travelers using BSSs to estimate the effect of demographic factors, bicycle ownership, and trip-level factors on the willingness and potential frequency of BSS usage. In addition, a latent class model is built to analyze the different aspects of theses systems concerned with different types of urban travelers. It is found that respondents’ age, occupation, income, mode combination, and the proximity of origin or destination to the docking station, etc., influence the willingness and frequency of using BSSs. In addition, respondents generally value features such as the proximity of docking stations to trip destinations, safety to ride, and appropriate level of fare. However, different latent classes show a different preference for other features of BSSs. According to the model results, proposals are given for the improvement of the existing systems in Chinese cities.

Traditional villages serve as crucial places for the living transmission and conservation of Chinese cultural heritage. Yet many existing conservation practices, by emphasizing the technical repair of heritage elements rather than their symbiotic and systemic vitality, have failed to sustain those villages' cultural presence and reproduction. This imbalance has produced the dilemma often described as "cultural presence without effective articulation", triggering debates over both "de-activated protection", and "destructive preservation". Grounded in the theory of living heritage, this study adopts the biological metaphor of a "phenotypic expression system" to conceptualize the chain of cultural expression. It advances the "Relationship-Object-Practice" (ROP) framework, which integrates three interdependent dimensions: explicit heritage elements (object dimension), implicit heritage elements (relationship dimension), and cultural practices (practice dimension). Based on an empirical case study of Lijiatuan village in Shandong province, the investigation reveals that although the village retains a relatively complete set of heritage resources, the relationship dimension has not exerted sufficient efficacy in sustaining the living practice of heritage. Community networks have become weakened in their ability to regulate and activate collective participation, while the practice dimension has been narrowly conceived, diverting attention away from mechanisms that support cultural expression and reproduction. Consequently, the object dimension has suffered from inadequate reintegration of everyday functions, leaving the village exposed to the risk of cultural deactivation, in which heritage persists in appearance but loses its living significance. In response, this paper proposes a conservation turn oriented toward the living expression of heritage. From the relational dimension, it advocates collaborative governance that privileges community leadership while incorporating external assistance; from the object dimension, it permits the adaptive transformation of heritage elements to meet changing social needs; and from the practice dimension, it calls for systematic monitoring and carefully calibrated intervention to prevent cultural stagnation without suppressing organic evolution. Through this orientation, the paradigm of traditional village conservation can shift from "elemental maintenance" to "cultural sustainability", ensuring not only the preservation of heritage resources but also the regeneration of cultural vitality as a dynamic and evolving system of life.
