基于人体舒适度的北方公园绿地夏季小气候实测分析——以兰州市金城公园为例

Based on Human Comfort,the Summer Small Climate Measurement Analysis of Lanzhou City Park Green Space:Take Jincheng Park,for Example

以兰州市金城公园为研究对象,通过人体舒适度指数DI定量分析不同植物群落组成对小气候及其舒适度的影响。结果表明,人体舒适度指数DI能够准确反映兰州市人体舒适程度;公园内各植物群落对环境温度、相对湿度以及实时风速都有显著调节作用,空间内空气温度相较环境温度更为稳定,相对湿度较高;乔灌草、乔灌、灌草植物群落能有效调节环境小气候因子,乔草植物群落和裸露草地空间内气候因子调节不稳定,相较来说人体感受乔灌草植物群落、乔灌植物群落以及灌草植物群落空间环境较为舒适。

Taking Jincheng Park in Lanzhou City as the research object,the influence of different plant community composition on microclimate and its comfort level was quantitatively analyzed by human comfort index DI,and the results showed that the human comfort index DI can accurately reflect the human comfort level in Lanzhou.Each plant community in the park has a significant regulatory effect on the ambient temperature,relative humidity and real-time wind speed,and the air temperature in the space is more stable than the ambient temperature,and the relative humidity is higher;Qiao shrub,Qiao shrub and shrub plant communities can effectively regulate environmental microclimate factors,and the climate factors in the Qiao grass plant community and the bare grassland space are unstable,compared with the human body’s feeling of the Qiao shrub plant community,the Qiao shrub plant community and the shrub plant community space environment is more comfortable.
