Urban greenways are essential ecological infrastructure connecting residents to nature and enhancing well-being. However, previous research has largely focused on the health benefits and related spatial patterns of greenways, while their roles and mechanisms in promoting pro-nature behaviors remain underexplored. Pro-nature behaviors are external manifestations of connectedness with nature, forming a gradient from visitation to usage habits and alignment with nature, thereby fostering sustainable human–nature relationships and enhancing urban well-being. At the deepest level, alignment with nature refers to residents’ deep engagement with natural environments, characterized by immersive perception and environmentally responsible behaviors that reflect an awareness of human–nature interdependence. This study systematically reviews existing literature to explore how urban greenways promote residents’ pro-nature behaviors. Grounded in the theory of connectedness with nature, this study develops a hierarchical framework linking network–place attributes to multilevel pro-nature behaviors (visitation, usage habits, and alignment with nature) to guide a systematic review of 88 articles retrieved from Web of Science and Scopus. Results show that visitation and usage habits are shaped mainly by greenway connectivity of built environment elements and internal features such as facilities, maintenance, and social factors, whereas alignment with nature is driven by ecological connectivity and habitat quality. The study argues that enduring pro-nature behaviors emerge when greenways integrate two complementary attributes: network coupling that links urban systems and ecological corridors, and composite place-based qualities that sustain human–nature interactions. These findings offer theoretical and practical insights for designing and managing urban greenways that combine ecological functionality with social well-being and promote sustainable urban development.
Urban fringe areas are faced with remarkable contradictions between land supply and demand due to a lack of scientific planning. Rural hollowing is accompanied by a shortage of urban land, resulting in a loss of both land and employment for farmers as well as a destruction to the distinctive features of urban fringe villages. Therefore, it is necessary to explore a set of planning methods for urban fringe villages to satisfy the needs of urban and rural development. Firstly, this paper carries out a literature review on the evaluation of village development potential and the main factors affecting the development of urban fringe villages. Based on previous studies, the paper establishes a development potential evaluation system for urban fringe villages, employing the Analytic Hierarchy Process(AHP) method. In the end, taking the Shenshan Special Cooperation Zone as an example, the paper presents the types of village development and the corresponding planning strategies based on the results of village development potential evaluation.
Chlorides, sulfates, and heavy metals are the three main factors preventing the recycling of municipal solid waste incineration (MSWI) fly ash as an alternative material for cement clinker production, of which chloride plays the main role due to its extremelly hign content in fly ash. This study evaluated three wet -based pretreatment methods (water -washing, CO 2 -aided washing, and flue gas -aided washing) to remove chlorides using MSWI fly ashes from 13 incineration plants in China. Water washing was suitable for removing Cl - from MSWI fly ash containing a limited amount of less -soluble Cl-containing salts (Ca(OH)Cl, Ca 2 Al(OH) 6 (H 2 O) 2 Cl, and Ca 6 (CO 3 ) 2 (OH) 7 Cl). However, for fly ash with a significant proportion of these less -soluble Cl-containing salts, injection of CO 2 /flue gas during washing promoted their decomposition and increased the chloride removal rates by 2 -12%. Compared with chloride, the removal rate of sulfate was lower under all treatment scenarios and ranged from 7% to 47%. Therefore, caution should be taken when exploring techniques for the deep removal of chloride from MSWI fly ash, as sulfates may be the limiting factor in fly ash samples with low chloride contents when utilizing the fly ash for cement clinker production. Heavy metals in fly ash were not a limiting factor for any ash samples (either raw ash or treated ash) when utilizing the fly ash for clinker production. However, the dissolution of heavy metals in the washing solution deserves more attention, as a large amount of wastewater will be generated during wet -based pretreatment methods. This study confirmed that CO 2 /flue gas injection during washing promoted the removal of the less -soluble harmful components of fly ash, expanding the applications of ash materials.
With climate change and urbanization, flood disasters have significantly affected urban development worldwide. In this study, we developed a paradigm to assess flood economic vulnerability and risk at the urban mesoscale, focusing on urban land use. A hydrological simulation was used to evaluate flood hazards through inundation analyses, and a hazard-vulnerability matrix was applied to assess flood risk, enhancing the economic vulnerability assessment by quantifying the differing economic value and flood losses associated with different land types. The case study of Wangchengpo, Changsha, China, found average total economic losses of 126.94 USD/m2, with the highest risk in the settlement core. Residential areas had the highest flood hazard, vulnerability, and losses (61.10% of the total loss); transportation areas accounted for 27.87% of the total economic losses due to their high flooding depth. Despite low inundation, industrial land showed greater economic vulnerability due to higher overall economic value (10.52% of the total). Our findings highlight the influence of land types and industry differences on flood vulnerability and the effectiveness of land-use inclusion in urban-mesoscale analyses of spatial flood characteristics. We identify critical areas with hazard and economic vulnerability for urban land and disaster prevention management and planning, helping to offer targeted flood control strategies to enhance urban resilience.
Under the trend in climate change, global warming, and the increasingly serious urban heat island effect, promoting urban wind corridor planning to reduce urban temperature and mitigate the effect of urban heat islands has received widespread attention in many cities. With emerging awareness of the need to explicitly incorporate climate considerations into urban planning and design, integrating current spatial analysis and simulation tools to enhance urban wind corridor planning to obtain the best urban ventilation effect has become an increasingly important research topic in green city development. However, how to systematically carry out urban wind corridor planning by employing related technology and simulation tools is a topic that needs to be explored urgently in both theory and practice. Taking Zhumadian City in China as an example, this study proposes a method and planning approach that uses remote sensing (RS), geographic information system (GIS), and computational fluid dynamics (CFD) in an integrated way to understand urban landscape and to conduct urban wind corridor planning. The research results reveal that the urban form of Zhumadian City favors the development of urban wind corridors, and that the railway lines and some major roads in the city have the potential to be developed as the city's main wind corridors. However, there are still ventilation barriers resulting from the existing land use model and building layout patterns that need to be adjusted. In terms of local-level analysis, the CFD simulation analysis also reveals that some common building layout patterns may result in environments with poor ventilation. Finally, based on the results of our empirical analysis and local planning environment, specific suggestions are provided on how to develop appropriate strategies for urban wind corridor planning and adjustments related to land use planning and building layout patterns in order to mitigate the impact of the urban heat island effect.
