Abstract Wetland parks are an important part of urban ecosystems, characterized by artificial and natural features. While providing outdoor recreational space for residents, the aesthetics landscape also affect residents’ willingness to visit wetland park. Previous studies focused on ecological benefit. However, fewer systematic analyzed aesthetic qualities influencing elements parks. In this study, Wuping Qianlu Lake Park in Fujian Province, China was used evaluate visual quality park using Scenic Beauty Estimation method (SBE), features were obtained through Semantic Differential (SD) semantic segmentation technique. The regression model established SBE values as dependent variable, 23 independent variables. accessibility combined create four quadrants, which with K-means clustering diagnose existing problems. results study showed that two features, approach proportion water area weaker among types landscapes. man-made type most significant. Meanwhile, high enclosure had a significant sense rusticity, accentuating wildness plants. It less aesthetically pleasing poorest types. This provides diagnosing problems parks, evaluating assessment, theoretical technical support renewal construction.

Abstract Serving as the direct interface for interaction between waterfront and urban dwellers, street space environment significantly influences people’s living experiences social interactions. Despite progress in renovation development of streets, these areas remain underutilized lack vitality expected such locations. Using Hunhe Waterfront Streets Shenyang a case study, this research employed Baidu heatmap data Semantic Differential method to assess both behavioral perceived area. Subsequently, study explored main factors influencing streets from three aspects: accessibility, facility configuration environmental construction. It also examined key features that affect under visual perception. Additionally, performed coupling analysis explore relationship within streets. The results indicated density infrastructure commercial facilities, well continuity pedestrian paths, were vitality. degree motorization, green index building enclosure ratio affecting Moreover, coordination was relatively poor, leaving considerable room improvement. By integrating behavior their perceptions environment, its intrinsic connection with features. This work aids developing more effective user-centric design strategies offering practical guidance revitalization redevelopment.

Traditional street quality evaluations are often subjective and limited in scale, failing to capture the nuanced dynamic aspects of urban environments. This paper presents a novel data-driven approach for objective comprehensive evaluation using view images semantic segmentation. The proposed SP-UNet (Spatial Pyramid UNet) is multi-scale segmentation model that leverages power VGG16, SimSPPF (Simultaneous Spatial Channel Pooling), MLCA (Multi-Level Context Attention) attention mechanisms. integration effectively enhances feature extraction, context aggregation, detail preservation. model’s average intersection over union, Mean Pixel Accuracy, overall accuracy achieving improvements 5.83%, 6.52%, 2.37% mIoU, Accuracy (mPA), accuracy, respectively. Further analysis CRITIC method highlights strengths various dimensions across different areas. not only improves but also offers valuable insights managers enhance livability functionality

Currently, coordinated development in terms of perceived urban quality and function has become a key problem. However, there is an imbalance between the street environment amenities. It necessary to explore current status propose optimization strategies promote spaces. Dalian, China, was selected as study area. Based on space syntax, high-accessibility low-accessibility streets were sites. An evaluation system constructed part study. included quality. Data density diversity amenities obtained by establishing points interest (POIs). The subjective psychological perception calculated using view images (SVIs). Then, coupling analysis based conducted results indicated that differences levels regard spatial Dalian. Specifically, mainly concentrated central higher than streets. found had highest proportions advantage opportunity beauty lowest maintenance among improvement Openness As result analysis, this not only helps optimize layout improve environment, but also provides practical guidance for future design. Additionally, will help environments enhance overall livability environment.

Underground and over-ground structures are affected by the external forces (tsunami, earthquake, storm, etc.) that directly related to environment change in climate. For this reason, a complex CHESST (Climate-Human-Environment-Structure-Soil-Tunnel) interaction model is proposed research which categorized based on structure types (building, bridge, elevated, road/rail). The best selected AHP (Analytic Hierarchy Process) using LWST (Logical Weightage Selection Technique). depends modified logical scale. weightage matrices prepared for three criteria (Environment Climate, Social, Economic), sub-criteria under each criteria, goal (selection of model). selection technique validated acceptable rate decision sensitivity. elevated (alternative model) shows maximum value seismic sustainability index (SSI) among all alternatives results. Also, fluctuation strain found from shake table test most sustainable expressway according SSI because showing highest priority 0.368. However, there scope enhance future considering more alternatives, sub-criteria, etc.

Urban green spaces play a crucial role in providing social services and enhancing residents’ mental health. It is essential for sustainable urban planning to explore the relationship between human perceptions, particularly their visual comfort. However, most current research has analyzed using two-dimensional indicators (remote sensing), which often overlook perceptions. This study combined three-dimensional methods evaluate spaces. Additionally, employed machine learning quantify comfort green-space environments explored The results indicated that Kitakyushu exhibited moderate FCV an extremely low Green View Index (GVI). Yahatanishi-ku was characterized as having highest Tobata-ku demonstrated lowest Natural, GVI, openness, enclosure, vegetation diversity, landscape NDBI were positively correlated with ENVI negatively Vegetation diversity had impact on improving By integrating remote sensing street-view data, this introduces methodology ensure more holistic assessment of planners could use it better identify areas insufficient space or require improvement terms quality. Meanwhile, be helpful valuable input formulating effective policies overall environmental provides scientific foundation improve construction healthy cities.
