Abstract
Urban park is a component of urban green infrastructures, essential in urban ecosystems because it delivers various benefits to urban dwellers, from tangible to intangible values. Urban park is widely accepted as a friendly adaptive solution in the context of warmer cities worldwide due to climate change and urbanization impacts. This research quantified the cooling effect of small and medium-sized parks in Bangkok Metropolis and identified primary controlling factors. An integrated approach was adopted to achieve the overarching objectives, including image interpretation from various data sources and Trends-Breakpoints Detection Analysis (TBDA). The research findings revealed that summer’s most active cooling distance is around 100–200 meters. When the weather is cooler in winter, the cooling distance expands outward to + 400 and + 1,000 meters depending on park structures and neighboring backgrounds. A park in a region with denser vegetation should have a more moderate cooling effect. Increases in tree areas inside a park and their shape complexity can stimulate the cooling effect, especially in the cooler season. In contrast, the park’s water surface only contributes to the cooling effect during the hotter period. The research outcomes are helpful for urban planners in heat mitigation strategies using urban green infrastructures. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.
