Nature on our doorstep: How do residents perceive urban parks vs. biodiverse areas?

Landscape and Urban Planning, Journal Year: 2024, Volume and Issue: 247, P. 105059 - 105059

Published: March 23, 2024

The role of nature in enhancing urban well-being is well-established, but perceived naturalness may not always align with scientific definitions. Our study aimed to investigate whether areas selected for nature-related activities demonstrate increased biodiversity, offer diverse experiences, and integrate both social ecological perspectives. We bridge the gap between objective richness. Integrating environmental parameters, we considered indicators, such as presence rare species, subjective Extensive geotagged surveys among 401 working-age Warsaw residents, coupled field analyses, biodiversity data collected scale whole city, allowed juxtapose human perception tangible indicators. results revealed that only 14% locations identified by respondents natural were associated high biological diversity. In contrast, over 30% low diversity, lacking species. Factors like semi-natural vegetation types, distance from buildings, population density, water, noise, extreme temperatures found be significant. distinguished four types areas: close home, open grassland, naturalness, forested, reflecting different preferences alternative choices when high-quality are nearby. Most notably, parks emerged key contact, even though measures often low. This underscores need a comprehensive understanding how residents interact value spaces, bridging experiences richness within city's green areas. highlights complex interplay physical properties individual perceptions, aesthetics influencing these interactions. particular, concept emerges critical factor, contrasting objective, quantifiable necessitating nuanced approach planning public health contexts cater needs city dwellers.

Investigating the performance of SDGSAT-1/GIU and NPP/VIIRS nighttime light data in representing nighttime vitality and its relationship with the built environment: A comparative study in Shanghai, China

Ecological Indicators, Journal Year: 2024, Volume and Issue: 160, P. 111945 - 111945

Published: March 1, 2024

In recent years, a substantial body of research has demonstrated the close relationship between built environment and urban nighttime vitality. While scholars have established slightly varied evaluation systems for environment, most utilized open-source light (NTL) data (2012 ∼ ) from Visible Infrared Imaging Radiometer Suite (VIIRS) sensor on Suomi National Polar-orbiting Partnership (NPP) Satellite to characterize However, with release high spatial resolution NTL Glimmer Imager Urbanization (GIU) Sustainable Development Goals 1 (SDGSAT-1) by Chinese Academy Sciences (CAS), more options are now available indicating Yet, no studies so far measured representational capability this new data. study, we selected Shanghai, one urbanized cities in Asia, as our area. We both GIU VIIRS represent vitality collected multidimensional geospatial big indicators environment. Various regression models were employed explore differences explanatory power when using different To obtain reliable conclusions, also divided study area according functional zone categories conducted experiments overall scale (entire area) local (different zones). The results showed that had higher R2 values at scale(0.529 > 0.268) (0.704 0.641, 0.701 0.408, 0.537 0.512, 0.674 0.589), stronger Furthermore, found use revealed an amplification effect, where impact certain representative factors (such road density, building height, vegetation coverage) was magnified, demonstrating pronounced heterogeneity. Our investigated performance SDGSAT1/GIU representing shows its potential application Additionally, reveals across zones. All these will provide valuable references city managers aspiring enhance help them make rational planning plans.

The research on identification and spatial pattern of urban mixed land-use: A case study of Chengdu

Ecological Indicators, Journal Year: 2023, Volume and Issue: 154, P. 110891 - 110891

Published: Aug. 28, 2023

In the context of urban quality enhancement, resilience focus, and promotion human-centered urbanization, a well-structured mixed land-use layout plays pivotal role in intensifying conservation land use, enhancing use efficiency, improving residents' living environments. The existing research on measuring parcels is hampered by lack area category data for POI point data, some methods neglect variations function quantities. This paper establishes an optimal calculation model incorporating weighted optimization introduces concept gravity to supplement entropy method, computes distribution patterns. analyzes both spatial patterns areas potential laws governing combination internal functions. results demonstrate that mixed-use exhibit pattern resembling "1 + n" pole-axis structure "T-type" development trend. Regarding combination, are generally found include commercial transportation provides suggestions discussions optimizing land-use, offering reference current planning.

Evaluation of Thermal Comfort in Urban Commercial Space with Vision–Language-Model-Based Agent Model

Land, Journal Year: 2025, Volume and Issue: 14(4), P. 786 - 786

Published: April 6, 2025

Thermal comfort in urban commercial spaces significantly impacts both business performance and public well-being. Traditional evaluation methods relying on field surveys expert assessments are often time-consuming labor-intensive. This study proposes a novel vision–language model (VLM)-based agent system for thermal assessment spaces, simulating eight distinct heat-sensitive roles with varied demographic backgrounds through prompt engineering using ChatGPT-4o. Taking Harbin Central Street, China as case study, we first validated accuracy ASHRAE scale evaluations of 30% samples (167 images) by 50 experts, then conducted simulations followed spatial interpretability analyses. Key findings include (1) significant correlation between VLM (r = 0.815, p < 0.001), confirming method feasibility; (2) notable heterogeneity across agents, demonstrating the VLMs’ capacity to capture perceptual differences among social groups; (3) analysis revealing higher eastern regions compared western central areas despite inter-role variations, consistency agents; (4) shade vegetation being identified primary influencing factors that contribute agent’s decision making. research validates VLM-based agents’ effectiveness evaluation, showcasing their dual capability replicating traditional while capturing group differences. The proposed approach establishes paradigm efficient, comprehensive, multi-perspective environments.
