However, most existing research focuses on vegetation growth during the growing season, limiting its ability to capture the seasonal dynamics and spatial impact factors of urban greening. To address this gap, this study uses the central urban area of Beijing as a case study. First, it extracts the 3D green indices from street view imagery and integrates them with the 2D green indices derived from remote sensing data to assess seasonal variations. The spatial clustering of the green indices and the impact of socio-economic and biophysical factors are then analyzed. Finally, multiscale geographically weighted regression is applied to examine the spatial heterogeneity of environmental impact factors on green indices distribution. The results show that the composite green index was 0.359 in summer and 0.304 in winter, based on subdistrict averages. Across subdistricts, the index declined by 13.27% on average from summer to winter. The green indices exhibited more substantial spatial autocorrelation in winter, with 2D green indices showing higher clustering than 3D indices. Socio-economic factors were the primary drivers of green indices overall, while biophysical factors had a more substantial impact during summer. Accordingly, the Central Business District and DingFuzhuang clusters should be prioritized for planting evergreen species and implementing a multi-layered vegetation structure. This study provides a quantitative foundation and practical insights for seasonal planning and adaptive optimization of urban green space system in densely developed urban environments.</div></div>","PeriodicalId":11459,"journal":{"name":"Ecological Indicators","volume":"178 ","pages":"Article 113828"},"PeriodicalIF":7.0,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144535966","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}

Among CES categories, aesthetic values ranked highest, while educational values received the least recognition. To support sustainable management of the Hara CMPA, targeted strategies should enhance environmental awareness, upgrade infrastructure, and incorporate local knowledge in planning.

The research introduces a semi-automatic method for classifying forest stands into vertical structure classes without the need for extensive fieldwork. The main strength and innovation of our approach is demonstrating that a model can be built and validated almost without field-acquired data. By processing point-cloud metrics derived from ALS data and employing machine learning techniques, particularly the random forest algorithm, the method generated a high-resolution vertical structure map across the country. The five-class model developed had a overall accuracy of 0.78. The results show that Polish forests are predominantly characterized by a single-story vertical structure, influenced by the dominance of Scots pine, with more complex structures in mountainous and biodiversity-rich areas. The methodology significantly reduces costs and time associated with traditional forest surveys, offering a scalable tool for forest monitoring, biodiversity assessment, and sustainable management, particularly under changing environmental conditions and habitat loss.</div></div>","PeriodicalId":11459,"journal":{"name":"Ecological Indicators","volume":"178 ","pages":"Article 113825"},"PeriodicalIF":7.0,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144522170","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}

Accordingly, this paper presents a first step to weld and fuse bark ecology and stemflow hydrodynamics. It is an effort to develop a physically-based understanding of the transport of water and matter (e.g., solutes, particulates, microorganisms) along tree stems using relevant equations to allow a more informed consideration of bark in green infrastructure initiatives. In particular, the hydrodynamical equations are based on the conservation of water mass, conservation of momentum, and conservation of scalar mass. These equations, coupled with contemplation of corticular life, underpin and substantiate bark’s unifying role as a modulator and cultivator. By elucidating the ‘black box’ of the tree stem and utilizing the formulations set forth in this paper, urban foresters and planners can develop green infrastructure to help advance ecosystem services and sustainability development goals (SDG), especially SDG 11 and SDG 15.</div></div>","PeriodicalId":11459,"journal":{"name":"Ecological Indicators","volume":"178 ","pages":"Article 113827"},"PeriodicalIF":7.0,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144518983","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 key criterion recommended as a proxy for terrestrial ecosystem function in bioretention basins is the number of <em>Lepidoptera</em> species supported in the larval stage by the plant genera selected by the designer. Designers can adjust plant choice to maximize this value, subject to tradeoffs with other design objectives and site-specific constraints.
