Taking Chengdu as an example, this study develops an improved two-step floating catchment area method that integrates traffic conditions. It dynamically assesses accessibility to <em>peri</em>-urban parks at different times during weekends and spatial inequalities, as well as explores the relationship between these inequalities and traffic conditions. The results indicate that under a 60-minute time threshold, there is significant two-tier differentiation in accessibility to <em>peri</em>-urban parks in Chengdu, with significant differences between different time points. Particularly during periods of traffic congestion, the issue of accessibility inequality becomes more prominent. This phenomenon highlights a strong correlation between congestion levels on routes to parks and inequality in park accessibility. This study provides a novel perspective and methodology for dynamically evaluating and optimizing accessibility to <em>peri</em>-urban parks, providing empirical evidence for urban planners in the planning of <em>peri</em>-urban parks and the design of transportation systems.

Scholars have studied the uneven distribution of urban greenery, but less attention has been paid to diverse plant uses and values by different sectors of the population and how those align (or not) with institutional plant preferences enshrined in GI policies. To address this gap, this article offers an in-depth case study of publicly-funded residential raingardens in a semi-arid city of the U.S. Southwest by drawing on an environmental justice framework. Through a mixed-methods approach we identify key criteria for residential plant selection among two groups from different economic and cultural backgrounds, and examine the desired benefits driving those preferences. More saliently, we found that plant preferences among low-income Hispanic residents tended to be at odds with institutional expectations of appropriate vegetation for GI installations in the context of increased heat and reduced water resources. Instead, they favored often-thirsty fruit bearing plants that provide cultural ecosystem services but are consistently excluded from the recommended plant lists used by program managers and expert practitioners. As practitioners and policy-makers seek to develop GI in historically underserved neighborhoods to reduce vulnerabilities to extreme heat, it is paramount to understand what people care to plant, what desired benefits they seek from those plants, and how they relate to plants in GI installations. Thus, this article argues that systematic attention to diversity in people-plant interactions is critical for implementing GI programs that are not only spatially, administratively, and financially accessible to underserved communities, but also culturally responsive to community identified needs. Moreover, by systematically documenting how different groups of people interact, use, and value vegetation this research adds to the movement towards integrating a biocultural approach to urban greening and to GI planning and implementation more specifically.</div></div>","PeriodicalId":54744,"journal":{"name":"Landscape and Urban Planning","volume":"257 ","pages":"Article 105317"},"PeriodicalIF":7.9,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143197850","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

However, the prevalence of urban expansion in the past few decades worldwide has resulted in uneven exposure to green space as a spatial concomitant of disordered urban development. Previous literature has mainly focused on examining the impacts of biophysical conditions, socio-economic development, and institutional capacity in shaping green space exposure, with little attention given to the role of urban sprawl. To address the gap, we developed a conceptual framework to explore the relationships between urban sprawl and green space exposure. We then used Amap real-time accessibility model, landscape metrics, and regression models to examine whether urban sprawl can lessen green space exposure in Chinese cities. Statistically, it is clear that southern and southeastern cities, as well as those at higher administrative levels, have greater green space exposure, while eastern and smaller cities tend to exhibit urban sprawl. Furthermore, we partially confirmed that urban sprawl can lessen green space exposure, especially in dispersed and fragmented Chinese cities. This result can be attributed to planning strategies that prioritize city cores over suburban areas. However, this is not the case for complex urban forms. We speculate that this finding is linked to the universal characteristics of unsystematic growth and edge development in Chinese cities.

However, few studies have explored how planting contexts influence the accuracy of remote sensing-based tree species identification in urban environments. This study introduced a planting context-specific modelling approach (i.e., models trained for street trees and park trees separately) for classifying seven dominant broadleaved tree species in the Brussels Capital Region, Belgium using airborne hyperspectral and leaf-on LiDAR data. This approach was compared to a traditional general modelling approach. Linear discriminant analysis with principal component analysis was employed to classify tree species at the individual tree level using different feature sets. Our results showed that a planting context-specific modelling approach with combined hyperspectral and LiDAR features achieved an overall accuracy (OA) of 84.2%. It improved the OA of LiDAR-based classifications by 7.6 and 8.9 percentage points for street trees and park trees respectively and of hyperspectral-based street tree species classification by 4.2 percentage points. The decreased discriminatory power of features in general models can be partly attributed to their sensitivity to planting context. We concluded that a planting context-specific modeling approach can enhance urban tree species classification, ultimately supporting improved urban forest management.</div></div>","PeriodicalId":54744,"journal":{"name":"Landscape and Urban Planning","volume":"257 ","pages":"Article 105316"},"PeriodicalIF":7.9,"publicationDate":"2025-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143104709","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}

We sampled bee-plant interactions from natural reserves across the <em>peri</em>-urban landscape of Fort Collins, Colorado (U.S.A.) and modeled pollination networks and bee foraging breadth in response to road and natural area density, reserve size, and background honeybee abundance. Four key findings emerged: (1) honeybees dominated pollination networks, representing 26% of recorded bee-plant interactions. High frequencies of honeybees reduced network modularity, but reserve size, natural area density, and seasonality did not predict network structure. (2) Honeybee frequency increased with road density and declined as natural area cover increased, indicating that higher residential densities drive honeybee pressure. (3) Patterns of floral visitation by honeybees and wild bees indicate substantial niche overlap, and foraging breadths of Megachilidae (leafcutter bees) and Colletidae (plasterer bees) declined as honeybee frequency increased. (4) Noxious weed species (e.g., <em>Convulvulus arvense</em> and <em>Carduus nutans</em>) had high rates of visitation by wild bees and were identified as both pollination network ‘hubs’ and ‘connectors’. We conclude that honeybee presence alters topology of bee-plant networks, and prioritizing creation of natural area reserves to maximize density of non-impervious cover may indirectly reduce competition with honeybees.

We stratify target zones into those requiring no adjustment, temporary non-adjustment, and those needing adjustment, based on the statistical distribution of land surface temperatures. We then employ landscape indices that encapsulate the spatial arrangement of green spaces and built environments, pinpointing specific structural elements within these zones for targeted thermal improvement. Adjustments are made to the building-green space landscape, focusing on high-temperature areas with the aim of aligning temperatures with low-temperature regions, guided by the identified structural elements indicated by landscape indices.

Spatial planning can serve as a backbone for inspiring and fostering the desired transformation of cities. However, to support this transformation, the challenge for spatial planning is to create unconventional plans that account for the complex trade-offs and interactions of different scenarios through participatory procedures. A promising approach for addressing this challenge is geodesign, since it couples spatial co-design with impact simulations. This paper aims to explore how, and with what effects, a geodesign process can support the co-creation of transformative urban plans that enhance biodiversity and ecosystem services while meeting urban development goals. A geodesign process was developed and deployed for a case study neighborhood in Stockholm, Sweden. Two scenario storylines were developed: one that follows the current city plan, and another one where the most transformative elements of the plan are further emphasized. Fourteen planning stakeholders divided into three groups translated the storylines into actual land use changes and explored the impacts of the two scenarios. The study findings indicate that the geodesign process enabled participants to develop transformative plans that address housing needs while also promoting biodiversity and ecosystem services through nature-based solutions. Participants showed high perceived desirability of TC scenarios in Skarpnäck but were mostly sceptical regarding the plausibility and probability of future implementation. Changes in perceived plausibility, desirability and probability comparing before and after the geodesign process were minor, with some inter-group variation. We recommend practical applications of geodesign to strategically involve key stakeholders throughout study conceptualization, scenario development, and model generation for better consideration of context. Enhancing geodesign tools for user-friendliness is also crucial. We suggest geodesign research to focus more on understanding its impacts on participants as well as scaling up for addressing complex challenges in metropolitan and landscape planning.</div></div>","PeriodicalId":54744,"journal":{"name":"Landscape and Urban Planning","volume":"257 ","pages":"Article 105303"},"PeriodicalIF":7.9,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143027359","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}
