摘要 [目的]了解佛甲草墙面绿化的降温增湿效应。[方法]利用新型墙面绿化装置栽植佛甲草进行墙面绿化,于7:00~19:00测定佛甲草表面、背面的温湿度和环境温湿度,研究光照度和环境温湿度对佛甲草墙面绿化降温效应的影响。[结果]在测定时间段内,佛甲草背面温度低于环境温度,平均低1.4℃;佛甲草绿化墙面的湿度高于环境湿度,平均高4.6%。佛甲草墙面绿化的降温效应与光照度和环境温度呈正相关,与环境湿度呈负相关,各因素对佛甲草墙面绿化降温效应影响的顺序依次为:光照度〉环境温度〉环境湿度。[结论]佛甲草进行墙面绿化可以有效降低墙体和空气温度,增加空气湿度,是适合墙面绿化的优良植物。 [Objective] The aim was to understand the effect of decreasing temperature and increasing humidity of the metope greening by Sedum lineare. [ Method] S. lineare was planted for metope greening by the new type metope greening equipment, the temperature and humidity of S. lineare surface and back and that of the environment were detected at 7:00 - 19:00, and the influences of illumination and enviroumental temperature and humidity on the decreasing temperature effect of the metope greening by S. lineare were studied. [ Result ] The temperature of S. lineare back was 1.4 ℃ lower averagely than environmental temperature and the humidity of the metope greening by S. lineare was 4.6% higher averagely than environmental humidity in the detecting time segments. The decreasing temperature effect of the metope greening by S. linear had a positive correlation with the illumination and environmental temperature and a negative correlation with enviroumental humidity. The order of the influences of each factor on the decreasing temperature effect of the metope greening by S. lineare was illumination 〉 environmental temperature 〉 environmental humidity. [ Conclusion] Using S. lineare for metope greening could decrease the temperature of metope and air effectively, increase the air humidity, and it was the good plant suitable for metope greening.
