As central-place foragers, wild bees are key witnesses of landscape transformations. Despite a prolific literature on their conservation, the impact of urbanization on bee communities remains unclear, yielding highly context-dependent results. In contrast, few data are available to assess the effectiveness of protected areas in conserving bee diversity. Our study aimed at quantifying the effect of land cover components and site protection status on the conservation value of bee communities within a highly anthropized landscape. We analyzed 6105 specimens across 91 sites, including protected areas, in the industrial belt of Hainaut, Belgium. We compared the effects of land cover components and site protection for several definitions of conservation value, including diversity indices and the number of threatened species. We found that urbanization increased diversity when abundance-based indices were examined, while simultaneously reducing the richness of threatened species. Flower-rich grasslands did not improve diversity indices, but they increased the number of threatened species. Forested areas were negatively associated with all diversity metrics except the number of threatened species. Similarly, protected areas displayed lower indices of diversity, but not fewer threatened species. This pattern aligns with the predominance of forested areas around protected sites. Our results suggest that the decline of threatened species in urban environments may be masked by high diversity among abundant species, a pattern detectable only through multiple metrics of conservation value. In addition, we reveal that existing networks of protected areas in the landscape may not be able to mitigate this decline, as reserves are not necessarily designed for the conservation of all species and may be biased towards certain types of environments.

作为中心地带的觅食者，野生蜜蜂是景观变化的重要见证者。尽管有关蜜蜂保护的文献很多，但城市化对蜜蜂群落的影响仍不明确，其结果高度依赖于具体情况。相比之下，很少有数据可以评估保护区在保护蜜蜂多样性方面的有效性。我们的研究旨在量化土地覆盖成分和保护地状况对高度人类化景观中蜜蜂群落保护价值的影响。我们分析了比利时海瑙省工业带 91 个地点（包括保护区）的 6105 个标本。我们比较了土地覆被成分和地点保护对保护价值的几种定义的影响，包括多样性指数和受威胁物种的数量。我们发现，在考察基于丰度的指数时，城市化增加了多样性，同时降低了受威胁物种的丰富度。花卉丰富的草地并没有提高多样性指数，但却增加了受威胁物种的数量。除了受威胁物种的数量外，森林地区与所有多样性指标都呈负相关。同样，保护区的多样性指数较低，但受威胁物种的数量并没有减少。这种模式与保护区周围以林区为主的情况相吻合。我们的研究结果表明，城市环境中受威胁物种的减少可能被丰富物种的高多样性所掩盖，这种模式只有通过多种保护价值指标才能发现。此外，我们还揭示了景观中现有的保护区网络可能无法缓解这种衰退，因为保护区并不一定是为保护所有物种而设计的，而且可能偏向于某些类型的环境。

Urban green infrastructure (UGI), an effective nature-based solution for urban sustainability, is also crucial in coping with the prevalent urban heat island (UHI) effect. However, how to enhance its cooling effect through optimized spatial patterns (e.g., city-level structure and network) has received little concern. Based on 310 Chinese cities, this study explored the multi-dimensional features of UGI and their interactive and conjoint impacts on surface UHI (SUHI) to identify the optimized cooling pathways under specific climatic backgrounds. In particular, the patterns of UGI were characterized by eight dimensions, i.e., quantity, patch size, shape complexity, fragmentation, contiguity, diversity, structure, and connectivity, each using one representative metric. Then the complex pathways of how UGI affected SUHI were investigated using the structural equation model, with the potential moderating role of climatic backgrounds taken into consideration. Results revealed that UGI affected SUHI through diverse pathways, and each pathway covered discrepant UGI features with various influencing directions and magnitudes. Among all pathways, direct impacts surpassed indirect ones, whose performances were largely diminished by multiple complex and counteracting mediation effects. Coverage, contiguity, structure, and connectivity, with the latter two dimensions largely neglected by previous studies, were found to be the primary cooling features. Among them, connectivity, despite its dominated impact in direct pathways, remained at low levels due to limited consideration and poor execution in previous planning practices. Typically, with the same UGI coverage, cities equipped with more clustered structure and connected network exhibited relatively lower SUHI intensity. For most cities, such enhanced cooling benefits can be achieved through mediation effects by smaller patches, more complex shapes, and shorter inter-patch distances. For cities in tropical and subtropical regions facing severer heat issues, however, it is recommended to optimize UGI design by adopting simple and regular patches with scattered distribution. This study extended the understanding of how to configure UGI for enhanced cooling effects from local to city level. The results may benefit urban planners pursuing climate resilient cities.

城市绿色基础设施（UGI）是一种有效的基于自然的城市可持续发展解决方案，对于应对普遍存在的城市热岛效应也至关重要。然而，如何通过优化空间格局（如城市层面的结构和网络）来增强其降温效果却很少受到关注。以中国310个城市为研究对象，探讨地表热流指数的多维特征及其对地表热流的交互和联合影响，以确定特定气候背景下地表热流的优化降温路径。其中，UGI模式的八个维度，即数量、斑块大小、形状复杂性、碎片化、邻近性、多样性、结构和连通性，每个维度都使用一个代表性度量。在考虑气候背景的潜在调节作用的基础上，利用结构方程模型研究了UGI影响SUHI的复杂途径。结果表明，UGI通过多种途径影响SUHI，每种途径覆盖了不同的UGI特征，其影响方向和程度各不相同。在所有途径中，直接影响超过间接影响，间接影响的效果在很大程度上被多重复杂和相互抵消的中介效应所削弱。覆盖、邻近、结构和连通性是主要的降温特征，而后两个维度在很大程度上被以往的研究所忽视。其中，连通性尽管在直接路径中发挥了主导作用，但由于以往规划实践中考虑有限和执行不力，一直处于较低水平。一般来说，在UGI覆盖相同的情况下，集群结构和连通网络较多的城市SUHI强度相对较低。对于大多数城市来说，这种增强的降温效益可以通过更小的斑块、更复杂的形状和更短的斑块间距离来实现。而对于炎热问题较为严重的热带、亚热带城市，建议优化UGI设计，采用简单、规则、分散分布的斑块。本研究将如何配置UGI以增强冷却效果的理解从地方扩展到城市层面。研究结果可能有利于追求气候适应型城市的城市规划者。

Sustainable urban planning requires identification of priority areas for people and biodiversity that should not be lost due to urban growth. We present a spatial prioritization of urban green areas of the Helsinki metropolitan area, Finland, to identify those areas that are needed to preserve both urban biodiversity and the equitable provision of recreational green spaces among all city districts. The suitability of urban areas for the Biodiversity Quality attributes of ten taxonomic groups were used as a surrogate for biodiversity, and the proximity of green areas to each city district while accounting for realistic travel times for accessibility. Overall, there was a great mismatch between areas identified as most important for supporting biodiversity vs. those important for equitable access to recreation. Based on a surrogacy analysis, accessibility was a better surrogate for biodiversity than vice versa. When urban green spaces were prioritized over both biodiversity and accessibility, higher contributions to both objectives could be achieved. A balanced prioritization that considers both objectives and includes currently protected areas can be used to inform land-use planning about the most important unprotected green areas from the biodiversity and recreational equitability perspectives. Low-priority areas would be preferred for new urban development to minimize impacts to biodiversity and recreation. Moreover, overlays between biodiversity, accessibility, and ecosystem sensitivities to anthropogenic disturbances inform local-scale planning and green area management. Systematic analyses, such as spatial prioritization, can facilitate transparent and unbiased urban planning, which accounts for the spatial complementarity of areas important to both people and biodiversity.

可持续城市规划要求确定人类和生物多样性的优先区域，这些区域不应因城市发展而丧失。我们对芬兰赫尔辛基大都市区的城市绿地进行了空间优先排序，以确定哪些区域既需要保护城市生物多样性，又需要在城市各区公平提供休闲绿地。城市区域对十个分类群组的生物多样性质量属性的适宜性被用作生物多样性的代用指标，绿地与各城区的临近程度也被用作生物多样性的代用指标，同时考虑到实际的交通时间。总体而言，被认为对支持生物多样性最重要的区域与对公平获得娱乐机会最重要的区域之间存在很大的不匹配。根据代用性分析，可达性比生物多样性更好地代用生物多样性。当城市绿地的优先级高于生物多样性和可达性时，对这两个目标的贡献都会更大。从生物多样性和娱乐公平性的角度来看，考虑到这两个目标并包括当前受保护区域的平衡优先级排序可用于为土地利用规划提供有关最重要的未受保护绿地的信息。低优先级区域将优先用于新的城市发展，以尽量减少对生物多样性和娱乐的影响。此外，生物多样性、可达性和生态系统对人为干扰的敏感性之间的叠加也为地方规划和绿地管理提供了信息。空间优先级排序等系统分析可促进透明、无偏见的城市规划，考虑到对人类和生物多样性都很重要的区域的空间互补性。

Parks provide environmental and recreational services to urban areas, and are valuable for human health and social cohesion. Current literature demonstrates the positive influence of urban parks on property values. This work, which typically examines the relationship between proximity or quality of parks and surrounding property values, assumes the value of park attributes is not influenced by neighborhood context. However, there is a gap in understanding how the value of park attributes varies across neighborhoods with different socio-economic and racial demographics, particularly in highly segregated cities. Using spatial data on park attributes, home values, and neighborhood demographics in the Twin-Cities area in the United States, we investigated how willingness to pay for park characteristics vary by neighborhood income and race characteristics. Some park attributes such as tree canopy and the presence of a dog park had positive and significant impacts on property values across neighborhoods of varying race and income characteristics, whereas park size, bike trail access, and presence of water bodies in parks had positive or negative effects on property values depending on race and income of the surrounding neighborhoods. Our analysis helps to understand how park investments in neighborhoods of varying race and income may differentially affect housing market dynamics with theoretical and practical implications for addressing green gentrification.

公园为城市地区提供环境和娱乐服务，对人类健康和社会凝聚力很有价值。目前的文献证明了城市公园对房地产价值的积极影响。这项工作通常考察公园的邻近性或质量与周围财产价值之间的关系，并假设公园属性的价值不受社区环境的影响。然而，在了解公园属性的价值如何在不同社会经济和种族人口统计的社区中变化方面存在差距，特别是在高度隔离的城市中。利用美国双城地区的公园属性、房屋价值和社区人口统计数据，我们调查了社区收入和种族特征对公园特征的支付意愿的影响。一些公园属性，如树冠和狗公园的存在，对不同种族和收入特征的社区的财产价值有积极而显著的影响，而公园的规模、自行车道的通道和公园内水体的存在对财产价值有积极或消极的影响，这取决于周围社区的种族和收入。我们的分析有助于理解不同种族和收入社区的公园投资如何对住房市场动态产生不同的影响，对解决绿色高档化具有理论和实践意义。

Community green spaces play a crucial role in providing leisure services by offering accessible areas for recreation, relaxation, and social activities. However, little is known regarding their impact on leisure service benefits perception (LSBP) in peri-urban areas over space and time. Taking Huadu District of Guangzhou in China as a case study area, this research assesses community green space quality, estimating LSBP with human-centric green space images and deep learning. Desktop mapping is employed to explore the spatial distribution of perceived leisure benefits, and geographically weighted regression (GWR) is adopted to examine the associations between the visual environment and LSBP. The results indicate that generally more leisure benefits (i.e., physiological, psychological, social, and cognitive benefits) of community green spaces are perceived during the day than at night. Some community parks and blue spaces demonstrate significant transitions from high LSBP during the daytime to low LSBP at night. Further, the five environmental visual elements, including green views, sky visibility, landscape diversity, walkability, and visual crowdedness, show varying associations with LSBP across both space (e.g., in high-quality residential areas and along community main roads) and time (e.g., during the day and at night). The findings provide empirical evidence for improving the planning of all-day leisure services in peri-urban community green spaces so that residents’ well-being and life satisfaction can be enhanced.

社区绿地在提供休闲服务方面发挥着至关重要的作用，它为休闲、放松和社交活动提供了便利的场所。然而，人们对城市周边地区休闲服务效益感知（LSBP）的时空影响知之甚少。本研究以中国广州市花都区为例，利用以人为中心的绿地图像和深度学习方法估算社区绿地质量的LSBP。采用桌面映射法研究休闲感知效益的空间分布，采用地理加权回归法研究视觉环境与休闲感知效益的关系。结果表明，社区绿地的休闲效益（生理、心理、社会和认知效益）在白天比在晚上更明显。一些社区公园和蓝色空间表现出从白天高LSBP到夜间低LSBP的显著转变。此外，五个环境视觉元素，包括绿色景观、天空能见度、景观多样性、可步行性和视觉拥挤性，在空间（如高质量住宅区和社区主干道）和时间（如白天和晚上）上都与LSBP表现出不同的关联。研究结果为完善城市周边社区绿地全天休闲服务规划，提高居民幸福感和生活满意度提供了实证依据。

Urban design significantly influences the physical activity (PA) behaviors of residents, impacting public health and well-being. This study examines how the built environment, social structures, economic conditions, and political context shape PA behaviors in three socioeconomically diverse neighborhoods in Bilbao, Spain. Using the Photovoice method, forty-one participants documented and discussed urban design features that affect their PA, fostering deep community engagement. A thematic analysis of 117 photographs identified four overarching factors influencing PA across all socioeconomic groups: 1) availability and quality of urban spaces for PA; 2) walkability and pedestrian infrastructure; 3) perceived safety and security; and 4) management of community assets. These factors were shaped by public space accessibility, topography, traffic-pedestrian interactions, and the extent of community involvement in urban planning. The study highlights the importance of inclusive, participatory approaches in urban planning to address health disparities and promote active, sustainable communities. Participants suggested specific interventions such as improving pedestrian infrastructure, enhancing safety measures, and increasing community-led management of shared assets to encourage active living. By emphasizing the role of social policies and community engagement, these findings provide a foundation for policymakers to develop strategies that promote equitable access to active living environments for all residents. While the study's insights are context-specific to Bilbao, they offer valuable lessons for similar urban settings, highlighting the potential of community-based approaches in fostering healthier and more inclusive cities.

城市设计显著影响居民的身体活动（PA）行为，影响公共健康和福祉。本研究考察了西班牙毕尔巴鄂三个社会经济多样化社区的建筑环境、社会结构、经济条件和政治背景如何塑造PA行为。使用Photovoice的方法，41位参与者记录和讨论了影响他们的PA的城市设计特征，促进了深入的社区参与。对117张照片的专题分析确定了影响所有社会经济群体的PA的四个主要因素：1)PA的城市空间的可用性和质量；2)可步行性和步行基础设施；3)安全感；4)社区资产管理。这些因素是由公共空间可达性、地形、交通-行人互动以及社区参与城市规划的程度决定的。该研究强调了在城市规划中采用包容性和参与性方法以解决健康差距和促进积极、可持续社区的重要性。与会者提出了具体的干预措施，如改善行人基础设施、加强安全措施、加强社区主导的共享资产管理，以鼓励积极生活。通过强调社会政策和社区参与的作用，这些发现为政策制定者制定促进所有居民公平获得积极生活环境的战略提供了基础。虽然这项研究的见解是针对毕尔巴鄂的具体情况，但它们为类似的城市环境提供了宝贵的经验，突出了以社区为基础的方法在培育更健康、更包容的城市方面的潜力。

Background

Few studies have investigated the effects of green space exposure during individuals’ daily activities on respiratory health. This study aims to evaluate how exposure to green space both within residential vicinities and during out-of-home activities influences the incidence of acute respiratory illness (ARI) among older adults.

Methods

Participants were recruited from a prospective cohort of community-dwelling older people in Hong Kong, who were followed for two years to monitor the occurrence of ARI. Using GPS watches, we tracked participants’ movements for seven consecutive days to gather data on their daily paths. The time-weighted spatial averaging method (TWAM) was used to calculate daily exposure to green space, incorporating metrics such as the presence or absence of total green space and its subtypes, the normalized difference vegetation index (NDVI), canopy cover, and plant area index (PAI). Generalized linear mixed-effects models analyzed the association between these exposures and ARI incidence across warm and cool seasons, with restricted cubic spline models examining dose–response relationships.

Results

Among the 134 participants (average age 76.2 years, 82.8 % female), after adjusting confounders, significant protective effects against ARI were observed with increased exposure to canopy cover (odds ratio 0.36, 95 % confidence interval 0.14, 0.88) and PAI (odds ratio 0.38, 95 % confidence interval 0.17, 0.84) outside the home. In warm or cool seasons, total green space and its subcategories also had an inverse relationship with ARI, except for grassland. No significant relationships were observed with NDVI. The protective relationship between green space exposure and ARI incidence demonstrated a dose–response pattern, more pronounced in active mode. No residential green space exposures were significantly associated with ARI risk.

Conclusions

Increased green space exposure outside the home is associated with a reduced risk of ARI among older adults living in urban areas. These findings highlight the potential health benefits of engaging in outdoor activities within green environments for respiratory health.

很少有研究调查了个人日常活动中接触绿地对呼吸系统健康的影响。本研究旨在评估老年人在住宅附近和户外活动期间接触绿色空间如何影响急性呼吸道疾病（ARI）的发病率。方法从香港社区老年人前瞻性队列中招募参与者，随访两年以监测ARI的发生情况。使用GPS手表，我们连续七天跟踪参与者的活动，收集他们每天的路径数据。采用时间加权空间平均法（TWAM），结合总绿地及其亚型的有无、归一化植被指数（NDVI）、冠层覆盖度和植物面积指数（PAI）等指标，计算日均绿地暴露量。广义线性混合效应模型分析了这些暴露与温暖季节和寒冷季节ARI发病率之间的关系，限制三次样条模型研究了剂量-反应关系。结果在134名参与者（平均年龄76.2岁，82.8%为女性）中，调整混杂因素后，观察到在室外暴露于树冠覆盖物（优势比0.36,95%置信区间0.14,0.88）和PAI（优势比0.38,95%置信区间0.17,0.84）对ARI有显著的保护作用。在暖、冷季节，除草地外，总绿地面积及其亚类与ARI均呈负相关。未观察到与NDVI有显著关系。绿地暴露与急性呼吸道感染发病率之间的保护关系表现出剂量-反应模式，在活动模式下更为明显。没有住宅绿地暴露与急性呼吸道感染风险显著相关。结论：在城市地区的老年人中，增加户外绿地暴露与降低ARI风险有关。这些发现强调了在绿色环境中进行户外活动对呼吸系统健康的潜在益处。

Habitat fragmentation in agricultural landscapes threatens biodiversity. Enhancing landscape connectivity across cultivated areas requires a thorough understanding of farmers’ spatial considerations and their willingness to create semi-natural habitats. We therefore conducted a spatial choice experiment with farmers from ten European countries to assess their preferences for placing linear wildlife habitats (hedgerows and wildflower strips) at the field scale under different scenarios, as well as the role of farm and personal factors. A total of 471 responses were analysed using multinomial logistic regression and generalised linear mixed models. The results indicate that landscape conditions, including field shape, slope, soil quality, and pre-existing landscape features, exert a significant influence on farmers’ decisions, as do the size of machinery, cultural regions, attitudes towards biodiversity, and type of intervention. On the other hand, no statistical significance was found for other variables. In general, farmers’ choices were driven by a desire to minimise disturbance to field work, optimise productivity, increase biodiversity, and address specific environmental challenges. The insights into farmers’ decision-making from this study can inform ecological network planning to reduce transaction costs by pre-selecting likely adopters, and to mitigate resistance and lower financial compensation by identifying best-fit options aligned with farmers’ practices. Integrating these findings into geospatial models could improve predictions of the impact of spatially targeted biodiversity conservation strategies on landscape composition and future biodiversity trends in agricultural areas.

农业景观中栖息地的破碎化威胁着生物多样性。要加强耕地之间的景观连通性，就必须全面了解农民的空间考虑因素及其创建半自然栖息地的意愿。因此，我们对来自十个欧洲国家的农民进行了一次空间选择实验，以评估他们在不同情况下对在田地范围内设置线性野生动物栖息地（树篱和野花带）的偏好，以及农场和个人因素的作用。采用多项式逻辑回归和广义线性混合模型对 471 份回复进行了分析。结果表明，地形条件（包括田地形状、坡度、土壤质量和原有地貌特征）对农民的决策有重大影响，机械规模、文化区域、对生物多样性的态度和干预类型也有重大影响。另一方面，其他变量没有统计学意义。总体而言，农民的选择是出于尽量减少对田间工作的干扰、优化生产率、增加生物多样性以及应对特定环境挑战的愿望。本研究对农民决策的深入了解可为生态网络规划提供信息，通过预选可能的采用者来降低交易成本，并通过确定与农民实践相一致的最合适方案来减少阻力和降低经济补偿。将这些研究结果整合到地理空间模型中，可以改善空间目标生物多样性保护战略对农业地区景观构成和未来生物多样性趋势影响的预测。

Road verges have considerable potential to benefit wildlife, but in highly urbanised areas management often limits their value for biodiversity. Evaluating how the management of road verges affects wildlife, both directly and indirectly, provides opportunities to integrate biodiversity into urban planning, design, and management. We studied butterfly pollinators next to main roads across Singapore, a highly urbanised tropical city-state that envisions itself as ‘A City in Nature’. Using structural equation models we quantified how road verge habitat quality (nectar-floral diversity, structural complexity, size, and plant richness) and surrounding landscapes (traffic density and greenness as a ratio of green to concreted areas) directly and indirectly affected butterflies. We found direct positive effects of nectar-floral diversity and structural complexity within road verges on butterfly diversity (abundance and richness). While road verge size and plant richness had no direct effects on butterfly diversity, both had indirect positive effects by increasing nectar-floral diversity and structural complexity. Greenness at a landscape (≥ 500 m radius) rather than local (≤ 250 m radius) scale positively affected butterfly diversity. Traffic density had a direct negative effect on butterfly diversity likely though increased mortality due to collisions. Our findings offer valuable insights for city planners and policymakers, and suggest that simple management decisions, such as improving resource quality within verges, can have positive benefits for biodiversity in highly urbanised areas. As cities around the world develop policy mechanisms to create greener environments, our results highlight opportunities to improve road verges to benefit butterflies, a commonly used flagship taxon for biodiversity.

道路边缘对野生动物有很大的好处，但在高度城市化的地区，管理往往限制了它们对生物多样性的价值。评估道路边缘管理如何直接或间接地影响野生动物，为将生物多样性整合到城市规划、设计和管理中提供了机会。我们研究了新加坡主要道路旁的蝴蝶传粉者，新加坡是一个高度城市化的热带城市国家，它把自己想象成“自然之城”。利用结构方程模型，我们量化了道路边缘栖息地质量（花蜜-花卉多样性、结构复杂性、大小和植物丰富度）和周围景观（交通密度和绿色与混凝土区域的比例）如何直接和间接影响蝴蝶。研究发现，道路边缘花蜜多样性和结构复杂性对蝴蝶多样性（丰度和丰富度）有直接的正向影响。道路边缘大小和植物丰富度对蝴蝶多样性没有直接影响，但通过增加花蜜多样性和结构复杂性对蝴蝶多样性有间接的积极影响。景观（≥500 m半径）绿化对蝴蝶多样性的影响大于局部（≤250 m半径）绿化。交通密度对蝴蝶多样性有直接的负面影响，但可能会增加由于碰撞造成的死亡率。我们的研究结果为城市规划者和决策者提供了有价值的见解，并表明简单的管理决策，如提高边缘资源质量，可以对高度城市化地区的生物多样性产生积极的影响。随着世界各地的城市制定政策机制来创造更绿色的环境，我们的研究结果强调了改善道路边缘以造福蝴蝶的机会，蝴蝶是生物多样性的常用旗舰分类群。
