The cooling effect of urban parks (PCE) is widely recognized as an effective way to improve the thermal environment. While influence various background meteorological factors (BMFs) on PCE has been increasingly documented, further understanding these impacts, particularly across different types parks, remains insufficient. Here, we selected two typical fifteen with green space (PG) and blue-green (PB&G) in Shanghai, China for comparative studies. impact BMFs threshold value efficiency (TVoE) sampled under six dates were quantified through descriptive statistics correlation analysis. results showed that: (1) Compared PG, PB&G had a stronger effect, stable conditions (BMCs). (2) enable significant PCE, both PG better higher air temperature (Ta). (3) blue ratio (RBS) presented than (RGS) BMCs, especially BMCs lower relative humidity (Rh); thus, regulation RBS should be firstly considered PCE. (4) TVoE fitting was also less affected by area 0.93 ha encouraged optimal from cost-benefit perspective study area. These findings are essential decision-makers can provide actionable knowledge climate adaptation planning.

Climate changes have led to increasing global energy consumption, detrimental the sustainable development of society. Urban blue-green infrastructure (UBGI) can improve urban microclimate. However, influence intensity UBGI on microclimate has not been quantified deeply use efficiency water and greenery resources. To solve research deficiencies, this study numerically simulated for 44 scenarios with different resource configurations (various body areas coverages) in summer. Based simulations, developed novel mathematical models thermo-environment (BGTE) quantify UBGI. The results indicated that daytime synergies first increased then decreased time. significance time (t), area (Sw), tree coverage rate (TCR), shrub (SCR), grassland (GLCR) synergy was by artificial neural network: t (39.4%), Sw (22.6%), TCR (22.0%), SCR (13.2%), GLCR (2.8%). make overall effect relatively efficient, should be less than 10000 m2, greater 65%, close 15%. This provides practical ideas efficient

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.
