As cities expand rapidly, the combined effects of urbanization, global warming, and intensification Urban Heat Island (UHI) phenomenon have become more challenging for urban environments. In response, Green Infrastructure (UGI) has gained attention as a practical effective tool mitigating UHI improving climate change. Among various UGIs, parks been subject numerous studies due to their proven ability reduce air surface temperatures, improve local microclimates, enhance overall livability. This systematic review synthesizes existing body research identify key factors that influence cooling performance parks. A total 131 peer-reviewed between 2014 2024 were analyzed, focusing on both design-related site-related play pivotal roles in park’s effectiveness. Design-related include park size, shape, vegetation density composition, presence water bodies, impervious surfaces while encompass background conditions, proximity natural configuration surrounding The findings reveal tree coverage, bodies are most influential enhancing performance. For factors, wind speed direction emerged critical components maximizing benefits. Research also showed can affect by influencing airflow patterns shading. Understanding these dynamics is crucial worldwide they strive design address specific environmental climatic challenges. this offer guidance landscape architects planners, enabling them deliver enhanced benefits, especially when face rising temperatures an increasing number heatwaves.

The three-dimensional morphological analysis of urban buildings constitutes a pivotal component planning and sustainable development. Nevertheless, the majority current research is two-dimensional in nature, which constrains comprehensive understanding spatial–temporal evolution. existing body studies frequently fails to consider temporal dimension architectural change lacks detailed examination micro areas such as communities streets. In order accurately identify patterns evolution morphology, this study focuses on Yau Tsim Mong District Hong Kong, utilizing data. By innovatively integrating factors, constructing weight matrix, applying Moran’s I, conducts an in-depth quantitative Coverage, Staggeredness, Duty Cycle at community scale, neighborhood scale. From 2014 2023, global I key morphology indicators has exhibited marked increase, underscoring close interrelationship significant optimization between overall findings illustrate that architecture undergoing process agglomeration high homogeneity, with strategic shifts emphasizing efficient spatial utilization refined design. scale particular importance, its independent complete structure effectively captures local dynamics, revealing high-value low-value dispersion characteristics. This suggests are being constructed more compact manner level, reflects precision efficiency rationality planning. These provide valuable references for development governance cities. They enhance capabilities promote strategies, ensuring steady progress path efficiency, harmony, sustainability.

Understanding and recognizing urban morphology evolution is a crucial issue in planning, with extensive research dedicated to detecting the extent of expansion. However, as development patterns shift from incremental expansion stock optimization, related studies on meso- microscale face limitations such insufficient spatiotemporal data granularity, poor generalizability, inability extract internal patterns. This study employs deep learning meso-/microscopic form indicators develop generic framework for extracting describing meso-/microscale morphology. The includes three steps: constructing specific datasets, semantic segmentation form, mapping using Tile-based Urban Change (TUC) classification system. We applied this conduct combined quantitative qualitative analysis Binhai New Area 2009 2022, detailed visualizations at each time point. identified that different locations area exhibited seven distinct patterns: edge areal expansion, preservation developmental potential, industrial land pattern, rapid comprehensive demolition construction linear mixed evolution, stable evolution. results indicate phase, high-density areas exhibit multidimensional characteristics by region, period, function. Our work demonstrates potential grid providing scalable, cost-effective, quantitative, portable approach historical understanding.

Urban blue-green space cooling island effect (BGCI) is effective in improving the thermal comfort of residents. However, there little knowledge regarding diurnal variation BGCIs and influencing factors. Therefore, we selected Beijing as study area used ECOSTRESS LST data inflection–maximum perspective method to explore BGCIs. Additionally, investigated variations relative influence characteristics itself, well surrounding 2D 3D landscape metrics using boosted regression tree model. The results indicated that displayed distinct patterns. progressively increased from sunrise midday, decreased thereafter sunset, reached its peak around diminished a relatively low level constant intensity at night. water bodies exhibited significantly higher compared vegetation during day, particularly with difference mean (CI) 1.06 °C distance (CD) 63.27 m, while differences were minimal night CI 0.02 CD 9.64 m. features had more significant impact on midday (CI: 32.30% 13.86% night), influenced 26.40% 35.81% night). greater (52.87% 10.46% playing important role (15.56% 38.28% height, shape index vegetation, building coverage ratio opposite trends Optimizing spaces cost-effective than themselves for nighttime comfort, especially urban landscapes. These findings emphasize imperative essentiality exploring BGCIs, providing valuable information mitigating UHI effects.
