Urban blue-green spaces refer to the spatial system composed of various open spaces such as water bodies, wetlands, and green spaces within the territorial space. They play a crucial role in mitigating the urban heat island effect, reducing urban temperatures, and enhancing urban ecological resilience. However, current research lacks a systematic review regarding the selection of blue-green space objects, scale ranges, research methods, and influencing factors. Therefore, this paper analyzes the current research status, keyword hotspots, and research collaborations in the cooling effects of blue-green spaces. It also systematically summarizes the research scales, cooling research methods, and influencing factors of blue-green spaces, discusses the processes of their cooling effects, and reflects on current research limitations while looking forward to future directions.

摘要

Urban blue-green spaces refer to the spatial system composed of various open spaces such as water bodies, wetlands, and green spaces within the territorial space. They play a crucial role in mitigating the urban heat island effect, reducing urban temperatures, and enhancing urban ecological resilience. However, current research lacks a systematic review regarding the selection of blue-green space objects, scale ranges, research methods, and influencing factors. Therefore, this paper analyzes the current research status, keyword hotspots, and research collaborations in the cooling effects of blue-green spaces. It also systematically summarizes the research scales, cooling research methods, and influencing factors of blue-green spaces, discusses the processes of their cooling effects, and reflects on current research limitations while looking forward to future directions.
