Rapid urbanization, while transforming people's living environments, also brings a series of urban issues such as the heat island effect. The park is an effective means to alleviate effect in summer. How make better use cold formed by parks improve outdoor thermal environment important topic. This manuscript takes Xi'an research area, using remote sensing data source and combining field surveys, explore cooling characteristics built-up area. It demonstrated that, influencing factors islands are summarized: area perimeter park, water bodies, trees all positively correlated with surrounding building density plot ratio green space. A comprehensive scoring model for each factor established, principal component analysis method used determine weight indicator on design elements, among which space has greatest influence weight. demand Xi'an's analyzed, optimization strategies suggestions improving put forward from both inside outside park.

Outdoor Thermal Comfort Research and Its Implications for Landscape Architecture: A Systematic Review

Sustainability, Год журнала: 2025, Номер 17(5), С. 2330 - 2330

Опубликована: Март 6, 2025

Amid global warming and urbanization, outdoor thermal comfort has become a critical consideration in landscape architecture. This study integrates systematic review bibliometric analysis of 1417 empirical studies (1980–2024) sourced from Web Science, aiming to clarify the current state research, identify core themes, propose future directions. examines key evaluation models, influence spatial morphology, their practical applications using keyword co-occurrence, citation networks, thematic analyses. Findings show significant rise research over past decade, particularly tropical subtropical regions. Core themes include indices (PMV, PET, UTCI), microclimate regulation, important indicators (height-to-width ratio, sky view factor, greening). The field is increasingly shifting towards simulation tools (such as ENVI-met CFD) rather than traditional measurements, with artificial intelligence emerging tool for predictive regulatory purposes, though its application remains limited. However, much focuses on small-scale morphological optimization lacks framework representation. Future should prioritize developing comprehensive system adaptable diverse landscapes, investigating interplay between form comfort, advancing sustainable, low-carbon design strategies. insights this provide solid foundation improving guiding sustainable urban development through

• Urban tree canopy cover is a promising solution for mitigating heat island. Data-driven guidance on selection and planting locations still limited. Four research priorities are proposed, requiring collaborative effort. Cross-climate morphological physiological characteristics desired. Integration with atmospheric boundary layer models suggested.

Comprehensive analysis on the thermal comfort of various greening forms: a study in hot-humid areas

Environmental Research Communications, Год журнала: 2024, Номер 6(2), С. 025010 - 025010

Abstract The potential impact of greening on improving thermal environments is widely recognized. However, few studies have comprehensively evaluated the influence different forms greening, such as various tree crown widths, green facades, roofs, and their combinations, both outdoor indoor environments. In this study, we conducted an extensive investigation within a residential precinct at Guangzhou University by combining on-site measurements numerical simulations with ENVI-met model. Physiologically Equivalent Temperature (PET) Humidity Index (THI) were used to assess comfort. results indicated that planting trees had greater environment than facades effect increased width trees, maximum reduction 4.8 °C (0.2 °C) in PET (THI). Green can bring change up 101.9 W m −2 sensible heat flux, resulting 1.8 Ta (air temperature). Conversely, roofs composed grass exhibit minimal effects Finally, provide recommendations for construction renovation projects areas, focus hot-humid areas.
