摘　　要：文章以南京滨江公园为例,研究了5种不同结构植物群落的温湿度调节效应,并初步分析了绿量与降温增湿强度之间的关系。结果表明:植物群落的降温增湿效应具有季节性差异,春季和秋季乔灌草结构的植物群落降温增湿效益最为显著,而夏季乔草结构的群落降温效益最明显,乔木群落的增湿效益最好;绿量与降温增湿强度均为正相关关系,春季和夏季绿量与降温强度具有显著或极显著差异;绿量主要影响降温强度,对增湿强度的影响较小。Taking Nanjing Riverside Park as the object,the paper studied the temperature and humidity regulation capacity of 5 plant communities with different structures and analyzed the relationship between green quantity and the intensity of cooling and humidification efficiency. The results showed that the cooling and humidification efficiency of plant communities had obvious seasonal variation. The arbor-shrub-herb multilayer community had the highest cooling and humidification efficiency in spring and autumn,while in summer,the arbor-herb community had the highest cooling efficiency and arbor community had the highest humidification efficiency. Green quantity was positively correlated to the cooling and humidification efficiency in all 3 seasons,while it showed the significant or extremely significant variation in its correlation to cooling intensity only in spring and summer. Green quantity mainly affected cooling efficiency and had little impact on humidification efficiency.
