【摘要】 文章采用不同舒适性指标探究植物景观对福州高架桥下空间微气候舒适度的影响,结果表明,代表舒适性指标的典型变量V1主要受S指标(综合舒适度指数)的影响;代表微气候因子的典型变量W1主要受空气温度、环境平均辐射温度、相对湿度的影响;太阳辐射强度、空气温度、环境平均辐射温度与舒适性指标呈正相关,相对湿度、风速与舒适性指标呈负相关;S指标是较好的舒适性指标;乔灌草是桥下空间最佳的植物景观类型,降温幅度在1℃～2℃。该结果可为福州市高架桥桥下植物景观空间的热舒适环境提供评判依据。更多还原

【Abstract】 Different comfort indices are used to explore the effect of plant landscape on the comfort degree of spatial microclimate under Fuzhou viaduct. The results show that the typical variable V1,which represents the comfort index, is mainly affected by S index(comprehensive comfort index), and the typical variable W1, which represents the microclimate factor, is mainly affected by air temperature, ambient average radiation temperature and relative humidity; the solar radiation density, air temperature and ambient average radiation temperature are positively correlated with the comfort index, while relative humidity and wind speed are negatively correlated with the comfort index; S is a good comfort index; arbor-shrub-grass is the best plant landscape under the viaduct, whose cooling range is between 1 and 2 ℃ compared with other types of plant landscape. The results can be used to evaluate the thermal comfort environment of the plant landscape space under the viaduct in Fuzhou.更多还原
