Yet understanding how people perceive these intangible benefits remains challenging. This study refines existing CES research by integrating large-scale social media analytics with large language models (LLMs) to capture and interpret public perceptions of parks in Beijing’s core districts. Drawing on more than 46,000 user-generated comments, the LLM-based framework identifies six CES categories (i.e., historical &amp; cultural, aesthetic, recreational, social interaction, educational, and spiritual values) and evaluates their sentiment tendencies. The results reveal that aesthetic value is the most positively perceived dimension, while recreational, educational, and social interaction values show moderate emotional intensity, indicating potential areas for experiential enhancement. Historical &amp; cultural and spiritual values, though less frequently mentioned, generate strong positive affect when recognised. Integrating these findings through Importance-Performance Analysis highlights clear renewal priorities for Beijing’s Garden City initiative. Methodologically, the study demonstrates how LLMs can classify Chinese-language social media text with high accuracy (F1 = 0.8945) and minimal manual annotation, offering a scalable, interpretable, and cost-effective approach for CES assessment. The combined use of social media data, semantic modelling, and performance analysis provides transferable evidence for guiding park management and renewal in other high-density urban contexts.</div></div>","PeriodicalId":49394,"journal":{"name":"Urban Forestry & Urban Greening","volume":"117 ","pages":"Article 129263"},"PeriodicalIF":6.7,"publicationDate":"2026-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145894383","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A tree’s growth performance and ecosystem services such as evaporation and shading can also be affected by pruning. This research study investigated how the growth of naturally grown <em>Platanus x hispanica</em> trees in Germany differs from that of table-topped pruned trees of the same species. The influence of this kind of pruning on photosynthesis, leaf area, growth and ecosystem services was demonstrated. We found that leaf level photosynthesis of table-topped trees was 20 % higher and leaf level transpiration rate 56 % higher than in naturally grown trees of the same age. Conversely, canopy photosynthesis and canopy latent heat flux was significantly lower in table-topped trees (47 % and 82 %). Our results clearly indicate a decrease in both size and diameter increment for table-topped trees compared to naturally grown trees, which confirms the reduction in the physiological processes photosynthesis and transpiration on canopy level. The changed physiology resulted in reduced stem diameter growth for table-topped plane trees in the year after pruning for 39 %. Crown projection area and the crown volume of naturally grown plane trees is 2 times and 2.7 times higher than the ones of table-topped plane trees of the same diameter size, while leaf area is on average 30 % larger for table-topped trees. The allometric relationships clearly differed. Our results show that specific environmental conditions should be considered when pruning trees in terms of growth and ecosystem services. A possible reduction in growth and services due to pruning can be mitigated by improving site conditions (e.g., low soil sealing, large root volume). However, especially in water-scarce environments or with high soil sealing, the reduction in transpiration following this type of tree pruning can be potentially beneficial. Our study, though, did not investigate sociocultural motives or aesthetic reasons for pruning. Our investigations focused exclusively on the growth and ecosystem services of a single species, <em>P. x hispanica</em>. Future studies should fill this gap by conducting a holistic study of the ecological, social, and aesthetic impacts of tree pruning that also includes other species with different growth and drought characteristics.</div></div>","PeriodicalId":49394,"journal":{"name":"Urban Forestry & Urban Greening","volume":"117 ","pages":"Article 129252"},"PeriodicalIF":6.7,"publicationDate":"2026-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145894387","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study examines how equity has been conceptualized and operationalized in the compliance-driven GSI programs of Cleveland, Philadelphia, and St. Louis. Drawing on analysis of 40 planning documents and 23 practitioner interviews, we show that equity is often subordinated to hydrologic performance and cost-effectiveness, reflecting the dominance of regulatory mandates. While planning documents from the early 2010s offered limited and technocratic treatments of equity, practitioners today frame equity as a dynamic, negotiated process shaped by governance roles, community trust, and institutional constraints. The findings also demonstrate significant opportunities for integrating equity into stormwater management. The results suggest that equity is not a binary achievement, but a dynamic and iterative practice shaped by institutional roles, regulatory mandates, and community partnerships. We argue that achieving equitable outcomes through GSI requires moving beyond compliance-oriented planning towards collaborative, cross-sectoral and community-centered approaches that center social and economic equity. While this study focuses on a specific approach within urban greening, it offers broader insights into the dynamics of urban sustainability and resilience planning, particularly in contexts governed by top-down planning frameworks. In doing so, we contribute to scholarly conversations on how equity can be integrated into institutional planning and environmental governance.</div></div>","PeriodicalId":49394,"journal":{"name":"Urban Forestry & Urban Greening","volume":"117 ","pages":"Article 129256"},"PeriodicalIF":6.7,"publicationDate":"2026-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145894386","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Findings reveal that the excessive reliance on online street view imagery has introduced spatial biases in assessing urban GVI status. Methodological inconsistencies undermine data validity, such as inconsistent sampling intervals, image types, and image acquisition times. While technical improvements have introduced evolving variants, terms tend to reflect semantic fragmentation rather than conceptual renovation. The interchangeable use of similar expressions leading to terminological inconsistency and ineffective literature retrieval has become a prominent issue. To improve conceptual clarity and support cross-study synthesis, we propose aligning image types with objective, visible, and visual GVI concepts and advocate for transparent reporting at each methodological step. Future efforts are necessary to conduct GVI studies for multiple cities and climates, improve species' seasonal identification, and advance GVI measurement across diverse green space types.

Resource pulses during peak fruiting periods significantly enhanced frugivore stability, while nectarivores remained unstable due to spatiotemporally ephemeral floral resources. Spatial heterogeneity further modulated these effects: fragmented habitats limited fruit availability, thereby necessitating a dietary shift toward animal prey, which was associated with amplified community volatility. Our framework integrates diet composition, phenological timing, and “structural stability” to model non-equilibrium dynamics under urban change.
