This study bridges the gap in comprehending the mechanisms, processes, and content of landscape perception that previous studies have not fully addressed.

Furthermore, a novel method leveraging Large Vision Models for color analysis, semantic segmentation, object detection, and depth prediction is introduced. This method allows for the accurate extraction of objective features of urban landscapes and uses the Random Forest to analyze the nonlinear relationships between objective features and subjective perceptions. An empirical study conducted in Chongqing demonstrates that color features and spatial forms significantly influence landscape perception, similar to the landscape elements. Moreover, ablation experiments demonstrate that our approach, based on the biological vision process, improves accuracy and fit compared to existing methods.

We focus on the role of both formal institutions and the perceptions that people form of spatial features and their meanings and functions, and the manner in which these intermediaries shape human-nature interactions and the co-production of nature’s wellbeing impact. Our findings from quantitative and qualitative data demonstrate that urban nature contributes to all aspects of a five-dimensional notion of wellbeing. But social housing residents’ and young peoples’ ability to experience these benefits is limited. Informal mechanisms of social control such as perceptions of ownership of space and its appropriate uses, and fear of conflict and crime limit the extent to which residents access greenspaces and the activities within them. Together with formal institutions such as tenancy types, housing targets and criteria for optimisation of site allocation, they produce hierarchies of use of public greenspaces and reinforce existing divisions between people of different demographic and socio-economic status.

Here we fill these research gaps by testing the contribution of green areas composition and configuration in reducing air pollution, before and during the COVID-19 quarantine period, in the largest city of the Global South (São Paulo, Brazil). We relied on a model selection approach using hourly concentrations of different pollutants (CO, NO<sub>2</sub>, PM<sub>2.5,</sub> and PM<sub>10</sub>,) as response variables. As predictors, we consider meteorological variables, the amount and fragmentation of green areas (related to air quality regulation supply), the quantity of vehicle emissions (proxy of demand pressure), all this at different spatial scales (proxy of pollutant flows from emission to supply areas). Our results showed that higher tree cover and lower vehicular emissions decreased concentrations of CO, NO<sub>2</sub> and PM. Air quality regulation was higher in periods of low demand (start of quarantine), when compared to periods of high demand (before and the last part of quarantine). Lower levels of pollutants were associated with greater amounts of green areas at scales of up to 1,000 m from the air quality monitoring station. This indicates that the presence of green areas can have positive effects on air quality at distances of up to 1,000 m from the sites where pollutants are emitted.

This study focuses on a comprehensive spatiotemporal analysis of 647 national forest parks in urban peripheries across China from 2000 to 2021.

The findings reveal that (1) In contrast to urban parks, the geometric morphology of <em>peri</em>-urban parks has limited influence on cooling intensity.

The proportion of woodland in the park increases year by year, and the negative impact of cropland on the cooling intensity decreases from −4.788 in 2000 to −0.547 in 2021.

This study addresses this gap by selecting 14 typical pocket parks in Shanghai and collecting high-resolution canopy and thermal data using unmanned aerial vehicles (UAVs). Generalized additive models were applied to assess the relationships between thermal conditions and spatial variables. The cooling effects were quantified by comparing the relative differences in surface temperature (<em>T<sub>s</sub></em>) and air temperature (<em>T<sub>a</sub></em>) between the pocket parks and non-vegetated reference sites, while thermal comfort was assessed using the Universal Thermal Climate Index (UTCI). The results revealed that: (1) On average, <em>T<sub>s</sub></em> was 3.98 °C lower, <em>T<sub>a</sub></em> was 1.18 °C lower, and UTCI was 3.74 °C lower in pocket parks than in non-vegetated sites.

The long-term impact of such measures on the stability of the landscape at the catchment scale beyond the implementation site itself is critical to project success and for sustainable catchment management and needs to be considered by all stakeholders. It is challenging, however, to predict the overall contribution of meander restoration in stabilising the lower catchment and to make reasoned assumptions about the optimal placement, scale, and interconnected benefits of restoration projects based on an analysis of real-life cases due to the complexity and uniqueness of each catchment’s hydrology and the size and cost of such projects. Meanwhile, digital models can be utilised to test a wide variety of hypothetical futures so that the potential impacts of meander restoration can be understood in advance and limited resources can be better allocated to promote effective kinds of projects. In this study, computational modelling is employed to model the impacts of various upstream meander restoration scenarios on the downstream landscape due to erosion and deposition activities in northern England’s River Don catchment. The results indicate that compared to a baseline scenario, river restoration in tributaries effectively reduces downstream main channel sediment discharge and lateral migration activities. Upstream restoration projects prevent watershed deterioration more effectively than downstream projects. Clustering projects close to one other is more effective in reducing valley lateral erosion and deposition, as well as channel loading, compared to having projects dispersed across multiple tributaries.</div></div>","PeriodicalId":54744,"journal":{"name":"Landscape and Urban Planning","volume":null,"pages":null},"PeriodicalIF":7.9,"publicationDate":"2024-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142534910","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, little is known about their usability for urban residents and their potential to provide wild nature experiences across different urban environments. This paper examines the usability of WNAs in Vienna (Austria) through a spatial analysis of the institutional and physical barriers to use, considering barriers related to the availability, accessibility, and attractiveness of these greenspaces. A city-wide map of WNAs (n = 1298) was overlaid with spatial data on the presence of institutional and physical barriers, and complemented with a hierarchical cluster analysis to identify WNAs that share similar usability patterns. The cluster analysis confirms that WNAs vary significantly with regard to usability and that their usability is frequently constrained by the presence of multiple barriers. Furthermore, the usability of WNAs tends to be lower in high-density built-up areas, indicating that the possibilities to experience wild nature in the inner city are limited both in terms of lack of availability and relatively poor usability. We conclude that improving the usability of WNAs demands tailored and integrated approaches to urban planning and greenspace management and provide suggestions of how the usability of each identified WNA cluster can be increased.</div></div>","PeriodicalId":54744,"journal":{"name":"Landscape and Urban Planning","volume":null,"pages":null},"PeriodicalIF":7.9,"publicationDate":"2024-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142534909","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
