摘　　要：全球气候变化和城市化进程的持续推进,加剧了极端天气事件频发,采取“基于自然的解决方案”(NbS)缓解高温热浪对城市居民的健康风险具有重要意义。以福州的3种榕属树种——细叶榕(Ficus microcarpa)、高山榕(F.altissima)、雅榕(F.concinna)和2种常见优势树种杧果(Mangifera indica)和香樟(Cinnamomum camphora)作为研究对象,通过现场实验和生理指标测度等方法,探讨不同树种遮阳环境下的人体生理健康指标变化,以及不同树种遮阳环境对生理指标的影响程度。结果表明:1)相比其他树种遮阳环境,细叶榕遮阳环境下受试者表现为显著低体温和低脉搏的生理特征;2)进入细叶榕遮阳环境后,受试者的体温降低幅度显著大于香樟的遮阳环境,受试者的舒张压降低幅度显著大于杧果的遮阳环境;3)榕属树种遮阳环境下受试者体温降低的概率是香樟遮阳环境下的4.17倍,其中,细叶榕遮阳环境对受试者体温降低的影响显著大于其他树种的遮阳环境。研究结果有助于热带和亚热带城市的园林树种选择和优化,也为城市居民健康出行提供有效避暑建议。旨在揭示微观尺度上绿色空间提供的人类福祉,探讨城市优势树种如何发挥其独特的生态功能。The continuous process of urbanization results in frequent extreme weather events.With the rapid growth of population in global urbanization,more and more people are living in highly artificial urban landscapes.Urban ecosystems play a vital role in providing human benefits to maintain the stable development of urban systems and enhance their adaptability to climate change.Nature-based solutions(NbS)may be effective and sustainable urban planning methods that can have a positive impact on human health.In addition,NbS is essential to mitigate human health risks caused by heat waves and relieve the damage of extreme environmental events.From the perspective of ecosystem services of tree species,this study took three types of Ficus tree species,Ficus microcarpa,F.altissima,F.concinna,Mangifera indica and Cinnamomum camphora in the high-temperature city of Fuzhou as the research object.Through the use of multidisciplinary and integrated research tools such as geography,ecology,botany and medicine,we employed a field experiment using SPSS statistical software,Origin,with the experimental design of short-term exposure to nature and standard access to tree species in high-temperature.Further,we discussed the changes in physiological parameters under the canopy of different tree species,exploring the response characteristics of physiological health indicators to different tree species'canopy shades.This paper aims to reveal the human well-being provided by green space at the micro scale,and to explore how the dominant tree species make unique ecological differences in high-temperature city.The results showed that:1)The subjects showed the characteristics of lower body temperature and pulse rate under the shade of Ficus microcarpa.The body temperature under the canopy shades of Ficus microcarpa tree was significantly lower than that under the canopy shades of Ficus altissima tree by 0.10℃ and 0.24℃ lower than that under the canopy shades of Ficus concinna tree.The pulse rate under the canopy shades of Ficus microcarpa
