Study On Urban Waterfront Public Space Renewal Along the Grand Canal in Beijing's Urban Sub Center from The Perspective of Place Attachment

Urban renewal is a policy hot spot and a focus of work in the field of urban construction, which is realizing a major transformation from rough development to quality enhancement and organic renewal at the current stage. As an important waterfront space in Beijing, the Grand Canal is the memory and soul of Beijing’s development. The renewal of the public space along the canal play an important role for the overall renewal and development of the urban sub center. ‘Place attachment’ is an important theory to discover the emotional connection between people and places in the discipline of recreation geography. It has been used by relevant scholars at home and abroad to study human-land interaction in communities, urban parks and other places. Based on the problems of the public space such as inefficient use of residents and lack of emotional indentity and the growing needs of people for a better life, this study carries out the research on the renewal of urban waterfront public space along the grand canal based on place attachment, with the hope of addressing the lack of a sense of belonging and identity in the use of waterfront public space and supplement the updated method of public space in human-land interaction.

Application of artificial intelligence sensor and visual image technology in the analysis of hydrophilic space landscape characteristics

With the continuous development of intelligent sensor technology and artificial intelligence, the application of artificial intelligence feature recognition at the level of intelligent sensor information acquisition to urban landscape analysis has become a current research trend and hot spot, but also brings us new research directions and challenges. In this paper, the multi-sensor collaborative filtering algorithm is optimized, and a method based on evidence theory is proposed to deal with the fuzzy and unclear information generated in the process of multi-sensor collaboration. Then, the analysis and recognition of multi-sensor fusion information using AI technology are analyzed in detail. This paper discusses the problems in multi-sensor information fusion and related solutions. Combined with the key nodes of 3D object AI feature recognition, multi-sensor collaborative Dempster Shafer evidence theory and 3D convolutional neural network waterfront space landscape feature recognition sub-model are constructed, and the waterfront space landscape recognition analysis model is tested and analyzed. The results show that the multi-sensor information collection Kalman filtering fusion algorithm effectively realizes the recognition of landscape feature information and the filtering of irrelevant interference information combined with an artificial intelligence algorithm to build a landscape feature recognition model. Among all kinds of landscape recognition, the recognition effect of beach inflow is the best, and the recognition accuracy, recall, and F1 value are all above 95. However, the identification effect of hydrophilic plank roads and underwater breakwater is relatively poor. The recognition accuracy of the hydrophilic platform is the lowest at 83.16 % among the eight landscape types, and the recall rate of underwater breakwater is the lowest at 79.96 % among the eight landscape types. In general, the multi-sensor Kalman filtering algorithm information fusion model designed in this paper has higher recognition accuracy and better classification performance for the collection and classification of the entire landscape dataset. The work of this paper provides a new idea and direction for the design and application of waterfront landscape identification and analysis systems based on intelligent sensors and artificial intelligence technology and lays a certain foundation for the intelligent design of urban waterfront landscapes.

Planning Strategies for Cultural and Creative Industrial Parks in Urban Waterfront Spaces: A Case of Huai’an City’s Li Canal

As the base of urban resources, the water system is a solid foundation for the integrated development of “ecology, production, and life” in the city. Taking Huai’an Li-Canal as an example, we defined the problems of Li-Canal planning and proposed planning strategies for similar cities in China by combining the successful experiences in China through the detailed interpretation of the current situation of the Li-Canal waterfront space. The results provide a reference for the construction planning of similar urban waterfronts in China. We proposed optimized strategies to enhance the water space along the Canal of Huai for the future construction of a research framework considering the economic values of the Canal. The strategies can be used to evaluate the optimal effect of water spaces on the Canal.

Examining the impact of neighborhood environment factors on residents’ emotions during COVID-19 lockdown and reopening: A Wuhan study on mediation and moderation

Due to COVID-19, the urban lockdown has caused a significant impact on the mental health of residents. However, limited research investigates the role of neighborhood factors on residents’ mental health during and after the lockdown. This study examines Wuhan, the first city to experience the COVID-19 outbreak, employing multiple linear regression and XGBoost algorithms to analyze the emotional status and distribution of Wuhan residents. The goal of this study is to identify the moderating effect of the neighborhood environment scale on emotional positivity and the marginal effect of the neighborhood environment on residents’ emotions. The results of the study indicate that specific neighborhood environmental characteristics have varying effects on residents’ positive emotions, both before and after the COVID-19 lockdown. The green space ratio, attraction density, waterfront space density, and service facility density all positively affected mood within different distance ranges. Shopping facilities, on the other hand, had mainly positive effects during the open period, with negative effects during the closed period. Furthermore, this study determined scale thresholds where neighborhood environments had a positive effect on mood. For instance, attractions and waterfront areas improved the mood of residents in residential areas, up to at least 3 km away. Medical facilities had a positive effect on residents’ mood beyond 2.2 km. This study highlights crucial implications for planning and managing neighborhoods to promote resilience during future public health crises.

Study on the Redevelopment of the Hangang River Waterfront from an Urban Resilience Perspective

Cities worldwide are developing strategies to cope with heat waves, extreme colds, floods, wildfires, hurricanes, earthquakes, droughts, pandemics, and other disasters caused by climate change. To this end, a resilience theory is being expanded and applied as a methodology to secure social and spatial systems that respond to climate change while providing ecological habitats and spaces for more diverse human activities. This study evaluated resilient redevelopment strategies for the Hangang River in Seoul by drawing on practices grounded in resilience theory. This study analyzed the nine proposals from the Resilience by Design Challenge, which aimed to gather response strategies for climate change in the San Francisco Bay Area in 2017 to identify practical physical design and social system strategies. Each team’s strategy for implementing urban resilience focused on six categories: governance systems, financial planning, public engagement, accessibility, ecology, and diversity. The guidelines to consider during the redevelopment of the Hangang River in Seoul were formulated by applying these criteria to the review of the river. This process has also yielded the following implications and characteristics for resilient design. First, ensuring the resilience of a city necessitates prioritizing the resolution of regional imbalances. Second, the social and ecological resilience of cities is intricately intertwined. Moreover, comprehending the dynamics between the two can guide effective, resilient design. Third, resilient design’s spatial and temporal scales are extensive and varied, highlighting the importance of understanding the relationships among categories and subcategories at different hierarchies. Finally, the value of urban waterfront space, traditionally associated with positive cultural and economic contributions to cities, must be reevaluated more profoundly and meaningfully in light of climate change.

Optimization design of waterfront tour routes under thermal comfort assessment in summer—a case study of West Lake in Hangzhou, China

ABSTRACT The existing research on waterfront tour route planning suggests that thermal comfort assessment has a direct impact on people’s outdoor tour experiences. It contributes to understanding the thermal comfort regulation mechanisms of landscape nodes and the scientific planning of tour routes. However, the research in this area is relatively limited and faces complex issues in data processing and analysis. This study takes the West Lake waterfront tour route in Hangzhou, China, as an example. Through empirical research, it validates the feasibility of tour route planning guided by thermal comfort. It employs field surveys, on-site measurements, and data analysis methods primarily based on the Rayman software to explore the relationship between urban outdoor waterfront spaces and microclimates. The study reveals the following findings: (i) Extensive water bodies surrounding an area positively regulate local microclimates. The closer one is to the water and the more water surrounds the area, the stronger the microclimate effect. (ii) Factors such as spatial openness, waterfront orientation, prevailing monsoons, etc. all have certain impacts on the microclimates of the lake and lakeside spaces. (iii) Air temperature has significant variability in its impact on human thermal comfort, with different PET (Physiological Equivalent Temperature) values at each measurement point during different time periods. The study combines the actual human thermal comfort conditions at eight measurement points around the lake with existing tour routes. It proposes two practical tour route optimization designs based on real tour microclimate factors. These designs employ thermal comfort assessment methods to effectively enhance and improve human thermal comfort during tours. This research carries social value and provides new insights for mitigating urban waterfront space microclimates, enhancing tour comfort, and improving landscape environments.

FUNGSI SOSIAL RUANG PUBLIK (Studi Kasus Ruang Tepi Laut Kota Makassar)

This research is motivated by urban waterfront spaces that are experiencing changes in social function, from shared living spaces to private spaces to become a handful of people who are economically capable. This study aims to determine the social function of waterfront space in Makassar City. This research uses a qualitative approach with a case study type. Data collection was carried out through in-depth interviews, participatory observation and documentation. Handling of informants follows a purposive procedure, namely determining in advance the group of informants who will be used as data sources with certain criteria. The informants of this study consisted of the indigenous people of the city of Makassar, immigrant communities and urban spatial planning experts. The results of this study indicate that the city's waterfront space which was previously a space for living together, a place for fishing boats to dock and dock, a place for welcoming families out to sea, a place for bargaining for fish buyers, has now become largely privatized for capital accumulation. The daily activities of fishing communities, which are a social function of the waterfront, are increasingly fading along with the management of coastal space as a tourist spot. Spaces that used to be easily accessible, time-free, cost-free have now been turned upside down. These spaces are now only accessible to social classes who have economic ability. As a beachside public space, its social function is disrupted because not all levels of society can access it. As a result, socio-economic class is quite difficult because it requires a lot of money. Waterfront public space has been socially degraded based on economic capacity.

Current Utilization and Further Application of Zooplankton Indices for Ecosystem Health Assessment of Lake Ecosystems

For the sustainable use of lake ecosystem services—water resources, aquatic habitats for biodiversity conservation, and aesthetic values as waterfront space—ecosystem health assessments using biota are implemented as important national environmental monitoring projects. Zooplankton play a key role as an important linkage in the material circulation as secondary producers in lake ecosystems. At the same time, they influence the composition and biomass of other communities through biological interactions. In this review, we summarize useful zooplankton indices for ecosystem health assessment and suggest considerations for their use. Suggestions are provided for the practical application of indirectly measured zooplankton biomass, as well as the potential and limitations of eDNA application, which has recently been actively utilized in biological monitoring.

Sustainability Assessment of Urban Waterscape Belt Ecological Reconstruction Based on LCA–Emergy–Carbon Emission Methodology

Rivers play a key role in regulating urban ecology, which can improve urban climate while slowing the heat island effect. As one of embodied energy in the field of ecology, emergy theory can be used to quantitatively evaluate the ecological characteristics of a system. This will help to further explore urban ecological sustainability in this article. In this study, four ecological riverbank reconstruction projects have been executed to restore the ecology along the banks of the Jinchuan River in Nanjing, China, which focus on the key river–lakeside and waterfront space in the main urban area. The LCA–emergy–carbon emission method was applied through a series of indicators, including emergy indexes and carbon emission indicators. It is important to distinguish prior research, and few have utilized this approach on urban waterways and waterscapes. The results illustrate that the reconstruction system has obvious improvement significance to the whole river ecology. This change can also be seen when using LCA–emergy analysis. In a 20-year cycle, the emergy of the material production stage and maintenance phase account for a major emergy share, followed by the construction stage, transportation process, and design process stage. The sustainability (ESI indicator) has been improved after carrying out the reconstruction projects. By choosing water and gravel as the primary material, the carbon emission can be reduced. The water treatment process accounts for the vast majority of carbon emissions. Secondly, gravel also plays an important role in carbon emission. Finally, an improved measure (clean energy reuse) was conducted to enhance the ecology of the reconstruction projects and obtained a significant ecological sustainability boost.

Which Spatial Elements Influence Waterfront Space Vitality the Most?—A Comparative Tracking Study of the Maozhou River Renewal Project in Shenzhen, China

Urban waterfront renewal, especially public space improvement, is important for regaining waterfront space vitality. However, existing studies constrained by sparse and hard-to-access data are hard to explore how changes in spatial elements during waterfront renewal would affect space vitality. Waterfront space vitality comprises social vitality represented by public behaviors and economic vitality represented by urban functional facilities. Taking the Maozhou River renewal project in China as an example, we collect spatial elements and vitality on corresponding periods in 2018 and 2020 (before and after the renewal construction) and use multiple linear regression models to assess the relationships. We find that the functional diversity (e.g., commercial and cultural facilities) and design quality (e.g., path density and the shoreline’s proximity to the water) are the two most influential spatial elements affecting space vitality during waterfront renewal. Overall, the use of two-time datasets has generated strong evidence for measuring waterfront revitalization.

Towards Sustainable Urban Riverfront Redevelopment: Adaptability as a Design Strategy for the Hangang Riverfront in Seoul

The design of urban spaces, including waterfronts, must consider the flexibility to respond to urban and environmental changes and the continuity that respects the existing urban factors that have determined the essential characteristics of the place. The Hangang River in Seoul, South Korea, has been susceptible to significant changes over the years and has accumulated considerable historical traces and an irrevocable relationship with its urban contexts. On the other hand, as the country experienced rapid development, most urban plans have been executed based on shortsighted perspectives without considering sustainability. This study suggests adaptability as the main driver to achieve sustainability of the urban riverfront by viewing the site condition dichotomously. The components of the site were distinguished as fixed and variable factors. Considering fixed factors, six design intervention types were applied to the site through extensive macroanalysis and correlation studies, and each intervention was proposed to respond to the variable factors of the site. This study proposed four strategies to upgrade the riverfront as an adaptable space. First, five types of waterfronts were introduced with more distinct functions and identities to accommodate various activities. Second, commercial development was introduced to build a stable financial base that could respond to economic fluctuations. Third, the ecological waterfront space was expanded to react to climate change in the long term and achieve the goals of improving the microclimate, biodiversity, and educational function in the short term. Lastly, connective infrastructure was introduced to address the rapidly increasing demand for open space. The significance of this study was twofold. First, the site condition was interpreted more comprehensively by applying a framework for analysis by distinguishing the fixed and variable factors. Second, the strategy presented in this study can be applied to establish a waterfront redevelopment plan in other cities that have a context similar to the Hangang River of Seoul.

Effects of brief exposure to campus environment on students' physiological and psychological health.

Experiences in natural environments can enhance human wellbeing and promote the recovery of physiological and psychological health. During the COVID-19 pandemic, university students' activity off-campus was limited, thus, the campus environment was particularly important for the recovery of students' physiological and psychological health. Although the benefits of sustained natural exposure are obvious for people's physiological and psychological health, the effects of brief exposure on physiological and psychological are unclear. In the present study, four types of campus environments, including square space, dense forest space, sparse forest space, and waterfront space, were selected to explore the transient recovery effects of different types of campus environments. Sixty university students were recruited, measuring their systolic blood pressure, diastolic blood pressure, and heart rate as physical parameters to assess stress recovery. Respondents also reported scores about their personal feelings in questionnaires to evaluate their psychological states. Both physiological and psychological indicators responded to the brief natural exposure (5 min), and physiological and psychological health was restored. However, only the recovery amounts of psychological indicators were significantly different in waterfront space, dense forest space, and sparse forest space. These results indicate that being compare with other spaces, the brief exposure in the waterfront space was the most beneficial to students' psychological health recovery. This recovery was attributed to the great role played by the sense of escape, but after the brief exposure, the attraction and compatibility of the environment would hinder the psychological health recovery. In conclusion, according to tests on both physiological and psychological aspects, the waterfront environment on campus is the best choice for students' transient health recovery.

Restorative effect of audio and visual elements in urban waterfront spaces.

Urban waterfront spaces are often composed of built infrastructures and nature elements. Though citizens could take advantage of these public spaces to relax from daily work, its restorative potential has not been paid enough attention. In this study, the restorative effect and mechanism of different audio and visual elements in urban waterfront spaces was systematically studied. At the first stage, restorative potential of waterfront spaces was investigated and different elements with restorative effects were identified through an on-site survey, in which visual and auditory forms of environmental-nature, animal-nature, on-water human activities and on-shore human activities were identified. At the second stage, a series of laboratory experiments were conducted to explore the restorative function of the audio and visual elements. It is found that the degree of artificiality of waterfront space was a crucial factor influencing the restoration level of the space, and higher artificiality level of waterfront space resulted in lower level of perceived restoration. However it was available by adding visual and audio elements to the scene to facilitate the restorative effect in waterfront spaces with high-level artificiality. The effects of adding visual and auditory elements on psychophysiological restoration were explored, and elements that should be recommended and restrained were discussed. These findings would provide applicable suggestions for future design and rebuilding of urban waterfront spaces.

How Do Ecological and Recreational Features of Waterfront Space Affect Its Vitality? Developing Coupling Coordination and Enhancing Waterfront Vitality.

People are increasingly concerned with natural environment quality (NEQ) as well as recreation services (RS) as the popularity of natural experiences grows. Specifically, public spaces in ecologically sensitive areas must achieve coordinated eco-recreational development. Waterfront spaces fall into this category, providing a high-quality natural environment and facilitating various recreational activities. This paper uses two waterfront spaces, Foshan New City Riverfront Park and Nanhai Qiandeng Lake Park, as sample sites, divides 22 waterfront space samples into specific research objects, introduces dual variables for RS function and NEQ, and uses mathematical and statistical methods, such as Pearson correlation analysis, coupling coordination degree calculation, and redundancy analysis, to investigate the influence of different waterfront spaces on RS function and NEQ. Finally, we propose an optimization strategy for coupling and coordinating the development of the RS function and the NEQ of waterfront space. This paper found the following: (1) RS (number of public facilities) and natural environment quality (shoreline curvature) are the dominant factors in the vitality of waterfront space; (2) optimization of RS function will restrict the development of NEQ to a certain extent; and (3) the coupling and coordination of NEQ and RS function are positively related to the vitality of waterfront space. This study can be valuable for government officials and waterfront space planners as they develop social-ecological synergy models.

Analysis of Thermal Environment of Waterfront Space in Summer in Mountain City: A case study in Chongqing, China

A crucial component of the urban ecology, waterfront space plays a key role in mitigating the urban heat island effect. However, waterfront spaces in mountain cities differ greatly from those in plain cities in terms of spatial form and environmental factors. Accordingly, it is urgent to study and improve the thermal environment of waterfront spaces in mountain cities. According to the spatial morphological characteristics and shading means of the waterfront space in Chongqing, a typical mountain city in China, the summer thermal environment of the waterfront space has been studied through field measurements. The outdoor thermal environment factors assessed include air temperature, relative humidity, wind speed, and mean radiation temperature. The results showed that the cooling effect was more significant at 1 m from the water's edge and decreased as the elevation increased. Air temperature and humidity showed a clear stratification characteristic with increasing elevation. At the same time, viaduct-shading was the most effective way of reducing heat stress, followed by the combined shading of sun sails with building-shading, while tree-shading was the least. This study offers basic data for further study and optimization of shading strategies for waterfront spaces in mountain communities.
