摘要

Urban areas are increasingly vulnerable to heat waves and the urban heat island (UHI) effect, exacerbated by rapid land use changes and diminishing green cover. Enhancing urban resilience to climate change requires effective nature-based solutions, particularly the strategic integration of peri-urban green spaces. This study investigates the role of peri-urban green spaces (PUGS) in mitigating local land surface temperature (LST) in the English Bazar Urban Agglomeration (EBUA), Eastern India. The objective is to assess the spatial cooling potential of green edges and their contribution to thermal comfort and climate resilience. Field-based temperature observations were carried out along a designated transect across the PUGS during peak summer under clear sky conditions. Spatial analysis of temperature patterns revealed a significant cooling effect within green areas, with a maximum temperature difference of 6.89 °C at 16:00, emphasizing the role of vegetation in diurnal heat moderation. Central green sites consistently recorded the lowest temperatures, while outer, impervious zones exhibited higher heat intensities. Vegetation cover showed a strong negative correlation with temperature at 12:00 (R2 = 0.486), while outside impervious surfaces showed a positive correlation at 14:00 (R2 = 0.393). Public perception further validated these findings, with 73% of respondents acknowledging the cooling benefits of green spaces. The study advocates for “greening the edges” as a viable planning strategy to lower urban temperatures and enhance thermal comfort. Integrating peri-urban green spaces into city planning can support climate-resilient development and sustainable urban environmental management.
