摘要：为了解城市户外绿地夏季微气候对热舒适度的影响,以湛江市某花园为例,通过测定温度(Ta)、湿度(RH)、风速(Va)、太阳辐射(SR)等微气候参数的变化,量化分析不同景观空间微气候与热舒适度的相关性。结果表明,7个观测点的温度与WBGT呈线性正相关,温度越高WBGT越大,热舒适度越差;湿度过高或过低均会影响空间热舒适。所有测点的风速与WBGT相关性不显著,太阳辐射照度与开敞型空间WBGT高度相关,温度、湿度、太阳辐射之间均存在显著或极显著相关,风速对温度的影响效应呈负相关,对湿度呈正相关。温度对热舒适度的直接作用最大,湿度对热舒适度的直接作用次之,会通过太阳辐射因子或温度的间接作用共同影响热舒适度。此结果揭示了微气候因子及相互作用对城市户外空间夏季热舒适的影响,为促进生态城市建设提供了参考。
In order to know the impact of summer microclimate on thermal comfort of urban outdoor green spaces,the correlation between microclimate and thermal comfort in different landscape spaces is analyzed by measuring the changes of microclimate parameters,such as temperature(Ta),humidity(RH),wind speed(Va)and solar radiation(SR),through taking a garden in Zhanjiang City as an example.The results show that the temperature and WBGT are linearly and positively correlated in the seven observation points.The higher the temperature is,the larger the WBGT and the worse the thermal comfort is.Humidity levels that are either too high or too low affect the thermal comfort of the space.There is no significant correlation between wind speed and WBGT;solar radiation illumination is deeply correlated with WBGT of open space.There are significant or extremely significant correlations among temperature,humidity and solar radiation.The effect of wind speed on temperature is negatively correlated,and the effect on humidity is positively correlated.The direct effect of temperature on thermal comfort is the largest,the direct effect of humidity on thermal comfort is the second largest,and it also affects thermal comfort jointly through the indirect effect of the solar radiation factor or temperature.The research results reveal the impact of microclimate factors and their interactions on the summer thermal comfort of urban outdoor spaces,which can provide reference for promoting the construction of ecological cities.
