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.

Investigating the nonlinear impacts of urban landscape and climatic parameters on temperatures, a critical issue within climatology. Chengdu, characterized by its hot, rainy summers rapid development, serves as an ideal model to illustrate these dynamics. Our investigation utilizes advanced analytical methods such Random Forests (RF), SHapley additive explanation (SHAP), Partial Dependence Plots (PDP) analyze how factors influence air temperature (AT) land surface (LST). Significant findings reveal profound thermal heterogeneity across Chengdu's fabric, underscored spatially distinct phenomena where some regions exhibit strong contrasts in due varying factors. The study identifies relative humidity rainfall key drivers variations during summer months, reflecting specific idiosyncrasies. These insights are critical, they highlight planning green infrastructure can be strategically used mitigate adverse effects. research not only enhances understanding complex interplays microclimates but also offers new perspectives heat management. It contributes scientific community providing evidence-based strategies for planners counter island effect enhance resilience against climate change. This comprehensive analysis underscores importance incorporating multiple variables into models, lays groundwork more refined environmental policies practices.

Quantifying the emotional impact of street greening during full-leaf seasons in spring, summer, and fall is important for well-being-focused urban construction. Current perception models usually focus on influence objects identified through semantic segmentation view images lack explanation. Therefore, interpretability that quantify greening’s effects are needed. This study aims to measure explain emotions help planners make decisions. would improve living environment, foster positive emotions, residents recover from negative emotions. In Hangzhou, China, we used Baidu Map API obtain when plants were state. Semantic was separate plant parts images, enabling calculation Green View Index, Plant Level Diversity, Color Richness, Tree–Sky Factor. We created a dataset specifically designed purpose perception, including four distinct categories: pleasure, relaxation, boredom, anxiety. generated combination machine learning algorithms human evaluation. Scores range 1 5, with higher values indicating stronger lower less intense ones. The random forest model Shapley Additive Explanation (SHAP) algorithm employed identify key indicators affect Emotions most affected by Diversity Index. These have an intricate non-linear relationship. Specifically, Index (often presence 20–35 fully grown trees within 200 m images) greater significantly promoted responses. Our provided local planning departments support renewal Based our research, recommend following actions: (1) increase amount visible green areas low Index; (2) seasonal flowering like camellia, ginkgo, goldenrain enhance diversity colors; (3) trim safety visibility; (4) introduce evergreen cinnamomum camphor, osmanthus, pine.

Within globalization, the significance of urban innovation cooperation has become increasingly evident. However, faces challenges due to various factors—social, economic, and spatial—making it difficult for traditional methods uncover intricate nonlinear relationships among them. Consequently, this research concentrates on cities within Yangtze River Delta region, employing an explainable machine learning model that integrates eXtreme Gradient Boosting (XGBoost), SHapley Additive exPlanations (SHAP), Partial Dependence Plots (PDPs) investigate interactive effects multidimensional factors impacting cooperation. The findings indicate XGBoost outperforms LR, SVR, RF, GBDT in terms accuracy effectiveness. Key results are summarized as follows: (1) Urban exhibits different phased characteristics. (2) There exist between factors, them, Scientific Technological dimension contributes most (30.59%) significant positive promoting effect later stage after surpassing a certain threshold. In Social Economic (23.61%), number Internet Users (IU) individually. Physical Space (20.46%) generally mutation points during early stages development, with overall predominantly characterized by trends. (3) Through application PDP, is further determined IU synergistic per capita Foreign Direct Investment (FDI), public library collections (LC), city night light data (NPP), while exhibiting negative antagonistic Average Annual Wage Staff (AAS) Enterprises above Designated Size Industry (EDS). (4) For at developmental stages, tailored development proposals should be formulated based single-factor contribution multifactor interaction effects. These insights enhance our understanding elucidate influencing factors.
