Despite their ecological value and operational carbon sinks, the large-scale construction of public building-attached green spaces remains an overlooked source of urban carbon emissions. This study develops a process-based carbon accounting framework integrating quota-based emission factors, applied to three attached green space types (rooftop gardens, green squares, and sunken yards) in a representative public building in Wuhan, China. Construction activities were decomposed into 6 sub-projects and 22 unit processes. Results reveal total emissions of 2,080,646.86 kg CO2 (95% CI: 1,946,777–2,244,308 kg CO2), with an emission intensity of 95.12 kg CO2/m². Road engineering (808,761.21 kg CO2, 38.9%) and the base subproject (672,634.38 kg CO2, 32.3%) are the primary sources, while granite driveway construction and planting activities are the most emission-intensive unit processes. Emission intensity varied substantially, from 650.3 kg CO2/unit for permeable asphalt driveways to 0.32 kg CO2/unit for stone ball barriers. Scenario analysis shows that a 10% reduction in material consumption achieves the greatest reduction (137302 kg CO2), with road engineering and the base subproject contributing 75,990.68 kg CO2 and 61,311.49 kg CO2, respectively. LCA verification confirms the framework’s reliability (relative difference: 3.54%). The framework supports activity-level emission management and mitigation strategy selection for low-carbon urban green infrastructure planning.

Rapid urbanization has intensified the environmental impacts of residential neighborhoods as key nodes of urban energy consumption and carbon metabolism. This study integrated life cycle theory with emergy ecological footprint analysis to quantify the sustainability of a residential neighborhood in Wuhan. The analysis revealed distinctive patterns in renewable energy utilization, where rainwater chemical energy and earth cycle energy constitute the primary contributions, supplemented by rain geopotential energy and solar energy, with minimal wind energy participation. Assessment of Building L-6 over its 70-year service life demonstrated that the operational phase dominates the emergy ecological footprint (EEF) at 1.86E+07 hm(2), greatly exceeding contributions from pre-construction (1.072E+05 hm(2)), demolition (2.133E+4 hm(2)), and construction phases (1.14E+3 hm(2)). The neighborhood's total emergy ecological carrying capacity (EECC) of 1.50E+3 hm(2) was vastly overwhelmed by its cumulative EEF of 1.823E+8 hm(2), resulting in a significant ecological deficit (EEDs < 0). In order to verify the accuracy of the data, a sensitivity analysis was conducted. This severe imbalance indicated substantial environmental pressure, primarily attributable to long-term operational energy demand and material preprocessing. In response, this study proposes targeted strategies including enhanced renewable energy integration, optimized construction management, adoption of high-efficiency low-emission building systems, and reduced reliance on conventional cooling technologies. This research provides both a methodological framework for neighborhood-scale sustainability assessment and practical guidance for reducing environmental impacts in urban development.

Public building-attached green spaces are increasingly important urban carbon sinks, yet their carbon sequestration potential remains poorly understood and underutilized. This study quantified vegetation carbon storage across three attached green space typologies (green square, roof garden, and sunken courtyard) at a representative public building in Wuhan, China, using field surveys and species-specific allometric equations. Total carbon storage reached 19,873.43 kg C, dominated by the green square (84.98%), followed by a roof garden (12.29%) and sunken courtyard (2.72%). Regression analysis revealed strong correlations between carbon storage and morphological traits, with diameter at breast height (DBH) showing the highest predictive power for trees (r = 0.976 for evergreen, 0.821 for deciduous), while crown diameter (CD) best predicted shrub carbon storage (r = 0.833). Plant configuration optimization strategies were developed through correlation analysis and ecological principles, including replacing low carbon sequestering species with high carbon native species, enhancing vertical stratification, and implementing multi-layered planting. These strategies increased total carbon storage by 131.5% to 45,964.00 kg C, with carbon density rising from 2.00 kg C∙m−2 to 4.63 kg C∙m−2. The findings provide a quantitative framework and practical strategies for integrating carbon management into the design of building-attached green spaces, supporting climate-responsive urban planning and advancing sustainable development goals.

The reconstruction of old communities makes an outstanding contribution to, and holds practical significance for, livelihoods and ecological civilization in the urban renewal context. Clarifying the renovation intentions of residents is conducive to the effective implementation of reconstruction projects. This paper takes a typical old neighborhood in Wuhan as an example to survey residents’ living satisfaction and renovation intention. Multiple linear regression analysis, factor analysis, and correlation analysis were used to quantitatively screen, judge, and process sample data. The results show that residents’ living satisfaction and willingness to renovate were different under the dimensions of resident age and property rights, respectively. Most residents were dissatisfied with the living state of the neighborhood. Residents over 61 years old or those who held real estate certificates had a strong willingness to renovate and tended to accept a unified management manner after the renovation of the old neighborhood. Moreover, resident satisfaction with the internal road traffic, infrastructure, and building state significantly affected the residents’ overall satisfaction with the living environment in the old neighborhood, which should be given more attention to improve the residents’ willingness to support the renovation items. Furthermore, it was found that resident satisfaction with building conditions, infrastructure, internal road traffic, and public environment significantly impacted their agreement with the renovation in the old neighborhood. This investigation could provide a basis and guidance for the reconstruction and design of old communities.

Architectural images, experienced visually and spatially, embody urban culture, aesthetics, and identity, yet their suitability in urban communities remains underexplored. This study addresses this gap by evaluating the suitability of architectural images using the niche-fitness model, combined with residents’ perception assessments. Evaluation indicators focus on architectural form, color, features, and values to assess how well buildings align with residents and environmental contexts. The findings reveal significant variations in suitability across six studied buildings in a high-density community in Wuhan. One building showed high ecological adaptability and alignment with residents’ functional and aesthetic preferences, while others exhibited moderate to low suitability, reflecting mismatches with residents’ perceptions. The inharmonious adaptability of these buildings demonstrates the need to harmonize architectural images with residents’ psychological preferences to enhance community livability and identity. Combining Wuhan’s regional characteristics, suggestions for improving the governance of architectural images are proposed to address mismatches. This study analyzes the role of architectural image suitability in improving residents’ quality of life and shaping urban community characteristics. By offering a practical approach for guiding the renewal of architectural images in communities, this research contributes to creating livable and culturally resonant environments to support sustainable urban development.

The health of urban innovation ecosystems is crucial for smart and modern city construction.Considering the characteristics and formation mechanism of urban innovation ecosystems, an index system of health evaluation for smart cities is established.The combined DEMATEL-TOPSIS method was used to comprehensively evaluate the health of the innovation ecosystem in Wuhan from 2012 to 2020.Moreover, the cause-and-effect relationships among the indicators and the key impact factors are analyzed.The results show that per capita GDP, the number of users with fixed Internet broadband access, and road area per capita are the critical factors influencing the health status of urban innovation ecosystems.The centrality degrees are 1.640, 1.406, and 1.326, respectively, and the causality degrees are 1.264, 0.934, and 0.808, respectively.Through the analysis of closeness coefficients, it can be concluded that the health status of the innovation ecosystem in Wuhan is good and steadily increasing.Finally, policy recommendations for the health development of Wuhan's innovation ecosystem are proposed.

High-density communities, characterized by concentrated populations and compact built environments, often exacerbate issues such as green space fragmentation, uneven distribution, and intensified urban heat island effects. Investigating the spatiotemporal heterogeneity and evolutionary characteristics of landscape patterns driven by population density (POP), road density (RD), street-level GDP (GDPS), and nighttime light intensity (NTL) in Wuhan’s high-density communities using a geographically weighted regression (GWR) model is essential for informing sustainable urban planning strategies. The results showed that ED, PD, and SHDI exhibit consistent annual declines averaging 1.53%, 0.97% and 0.59%, respectively, while AI increased steadily at 0.11% per year. This indicates that human intervention has surpassed natural succession and become the dominant force in shaping landscape patterns. Among them, POP and RD are the direct driving factors for landscape pattern changes, while GDPS and NTL indirectly affect landscape patterns through economic structural adjustments and land use changes, forming differentiated spatial patterns in high-density communities. In terms of relationships, the GWR model performs better than ordinary least squares regression (OLS) by adjusting R2 and residual Moran’s I, significantly improving its explanatory power. This study demonstrates the effectiveness of the GWR model in revealing the spatiotemporal heterogeneity between socioeconomic factors and landscape patterns, providing a transferable analytical framework for high-density cities. It thereby offers empirical and methodological support for addressing regional ecological constraints and advancing sustainable urban renewal.

Urban expansion intensifies economic–environmental conflicts, making human settlement quality increasingly critical for sustainable development. This study applies ecological niche theory to evaluate the evolution of human settlement quality in the Wuhan Metropolitan Area (WMA) from 2014 to 2022 using 21 economic, social, and ecological indicators. The results reveal: (1) significant variations in niche-fitness values across subsystems, with Wuhan maintaining superiority (>0.820) despite a gradual decline, while peripheral cities—notably Huangshi, Tianmen, and Ezhou—consistently ranked lower (<0.610) throughout the study period; (2) three evolutionary trajectories emerged, characterized by continuous decline, inverted U-shaped development, and sustained growth, reflecting nonlinear dynamics and path dependence in the region’s development patterns. These findings underscore persistent core-periphery disparities within the metropolitan area, yet improved regional coordination is evident as inter-city evaluation gaps narrowed from 0.329 to 0.231 between 2014 and 2022. Based on these insights, tailored policy recommendations are proposed to address the identified disparities and promote balanced development. This study offers valuable theoretical and practical contributions toward achieving coordinated and sustainable development in metropolitan regions.

This study delves into an investigation of urban public outdoor spaces (POSs) from a health-oriented perspective, recognizing varied health needs encompassing physical, psychological, social, and environmental aspects. In this study, POSs of two typical government service centers (GSCs) were analyzed based on their structure, user demographics, and user satisfaction, revealing several problems with the current GSC POS designs. To address these problems, principles for GSC POS design were proposed for natural, playing, and social spaces and applied to redesign the Wuchang GSC. Firstly, through on-site surveys, questionnaire surveys, and data analysis, the existing problems in promoting residents’ health in the GSC POSs were revealed, such as the insufficient greening of natural spaces, lack of interest in playing spaces, and unreasonable design of the scale of social spaces. Based on the above analysis, a health design optimization principle based on Maslow’s theory is proposed. Firstly, improvement solutions were proposed and implemented for green spaces, such as using more diversified natural elements, zone differentiation, and landscape improvements to promote the health of users. Secondly, the leisure and sports needs of different age groups can be met simultaneously by diversifying the layout and functional settings of playing spaces. Finally, public spaces suitable for social interaction were redesigned to promote the psychological health of citizens in social activities by optimizing the scale of communication spaces. The proposed design optimization strategies for GSCs not only provide theoretical support for the healthy design of POSs but also provide useful references for the healthy development of urban public spaces.

Fragile ecosystems that are affected by erosion from high pollution environmental loads pose a serious threat to human health and well-being. The evaluation of regional environmental loads has become a major issue for eco-environmental conservation and management. As a key region in central China, Hubei Province relies on ecosystems and the environment, which offer an important foundation for sustainable development and continuous improvements in social productivity. For this study, seven influencing factors were selected, and a correlation degree model was applied to assess Hubei Province's environmental loads during the period from 1995-2019. The results show that the overall environmental loads exhibit a fluctuating decreasing trend in response to economic growth and development actions. Moreover, as eco-environmental pollution problems have been addressed and improved over time, the ecosystem operating status has been gradually optimized. Finally, the paper concludes with a proposal of specific measures designed to mitigate Hubei Province's ecological loading from the perspectives of industrial structure, public awareness and technological innovation.

This paper analyzed neighborhood residents’ cognition of and participation in low-carbon behaviors, basing on a questionnaire survey launched in a neighborhood in Wuhan, China. Results indicate that most respondents concerned the low-carbon impact on their daily lives and expected the government to make differences in low-carbon transition. Neighborhood residents’ participation in low-carbon behaviors was mainly reflected in three aspects: home energy conservation (HEC), efficient resource consumption (ERC), and recycling habits (RH), which were extracted from the five categories out of the 15 observed variables. Many interviewees had high level of participation in low-carbon behaviors that affect their economic interests. But these neighborhood residents rarely participated in public low-carbon behaviors such as planting trees or cooperative low-carbon behaviors. Therefore, these neighborhood residents’ participation in low-carbon behaviors was still on the initial stage. Specific proposals were put forward to promote urban low-carbonization further.

Urban sustainable development is important for addressing the urgent pressure of ecological transformation in China. This study used an improved emergy ecological footprint method and four indexes to evaluate the sustainability of the complex eco-economic system in Qingdao from 2004 to 2014 by determining the area’s emergy carrying capacity and emergy ecological footprint. The results show that Qingdao’s per-capita emergy carrying capacity decreased from 12.4305hm2/cap in 2004–11.3295hm2/cap in 2014, with a decrease rate of 0.840%. In contrast, the emergy ecological footprint per capita increased rapidly from 3.0609hm2/cap in 2004–25.4010hm2/cap in 2014, with an increase rate of 21.212%. Thus, the ecological overload increased over time. Qingdao experienced an expanding emergy ecological deficit beginning in 2009. Furthermore, the four sustainability evaluation indexes together indicate that Qingdao was drifting away from sustainability. Moreover, relevant socioeconomic factors were investigated using Pearson correlation analysis, and the results indicate that the largest correlation coefficient exists between the ratio of the output value of tertiary industry to gross regional domestic product and the per-capita emergy ecological footprint. Therefore, adjusting the energy consumption structure, decreasing dependence on non-renewable energy, increasing the diversity of bioproductive land types and developing high-level tertiary industries are conducive to promoting Qingdao’s sustainability. Additionally, the results provide a scientific reference and decision-making basis for regional sustainable development.

Engineering community is a new and rapidly growing research field of engineering construction and management.

Climate change has become a global issue influencing human survival and development while urban carbon emission is the main factor. As a fundamental building block of the city, neighborhood is not only the basic space to create a truly sustainable community but also the starting point for the use of low-carbon ideas and technologies to address climate change and promote the construction of a low-carbon city. Considering the significance of neighborhood planning on reducing carbon emissions, we proposed low-carbon neighborhood planning technologies from six aspects: layout planning, traffic planning, architecture planning and design, environment planning, municipal engineering planning and construction management. Moreover, we built an indicator system of low-carbon neighborhood based on these technologies from the perspective of “carbon source control” and “carbon sinks expansion” and used Analytic Network Process (ANP) to analyze the internal feedback and obtain the priorities. The system could be used to indicate low-carbon degree and provide measures for improvements. Furthermore, we carried out a case study using the proposed method for a neighborhood in Shandong province, China. Our practice has proved that the system could promote sustainable and low-carbon development of urban neighborhood and provide the government an effective tool.
