夏冬季城市公园微气候对人体热舒适度影响研究——以合肥市杏花公园为例

Study on the Effect of Microclimate in Urban Parks on Human Thermal Comfort in Summer and Winter—Take Hefei Xinghua Park as an Example

随着城市化进程的加剧,气候环境变化导致极端天气频发,高温天气和低温寒潮事件直接影响人体健康。通过微气候实地测量与问卷调查结合,研究城市公园夏冬2季对人体热舒适度影响。结果表明:(1)主观感受与人居环境气候舒适度评价指数之间有一定差异,游人心情、所处环境、运动状态等都影响人体热舒适度。(2)植物层次丰富的测点在夏冬2季可以有效地降温、增湿,植物在夏季调节微气候优势优于冬季,良好的绿色空间可以影响局地的微气候。(3)夏冬Pearson相关分析中,风速对人体舒适度的影响最大,并呈显著负相关。

Due to the worsening of climate and environmental changes during urbanization,the frequent occurrence of extreme weather events,and the direct impact of high temperature and cold wave on human health,a combination of microclimate field measurement and questionnaire surveys was used to study the thermal comfort of urban parks in summer and winter.The results showed that:(1)There was a notable difference between the subjective perception and the evaluation index of the climate comfort in human settlements.The mood of the tourists,their enjoyment of the environment,and their physical activity all affected the thermal comfort.(2)Measurement points with rich plant coverage were effective in cooling,regulating heat index,and increasing humidify in both summer and winter.Plants were more effective at regulating microclimate in summer than in winter,and well-maintained green space positively influenced the local microclimate.(3)In the Pearson correlation analysis of both summer and winter,wind speed had the greatest impact on human comfort,showing a significant negative correlation.
