城市绿地空间3种配置模式降温增湿效应比较

摘要

Magnolia grandiflora-Buxus sinica - Ophiopogon japonicas land （arbor-shrub-herbs）, Buxus sinica-mixed grass- land（shrub-herbs） and grassland were chose to analyze the effects of cooling and humidification. The results showed the effects of cooling and humidification in the arbor-shrub-grass were the best, the second was the shrub-herb type. The grass- land could regulate soil and air temperature and humidity, but its influence was slight. There were also signifant differences among the three plant disposition types, the order of synthetical ecological effects, from the best to worst, was arbor-shrub- grass type, shrub-herb type, and grass type.%选择广玉兰-瓜子黄杨-细叶麦冬植物群落（乔灌草）、瓜子黄杨-混合草坪植物群落（灌草）、草坪3种配置类型，对城市休闲区不同绿化类型的降温增湿效应进行了分析。结果表明，乔灌草绿地降温效应最佳，增湿效应最明显，其次是灌草绿地，草坪地虽具有一定的降温增湿效应，但是效果较差。不同配置类型的生态效应存在差异，其综合效应是乔灌草群落〉灌草群落〉草坪群落。
