摘要
屋顶绿化是改善生态环境、建设低碳城市的重要举措,屋顶绿化植物材料的选择是关系到生态效果好坏的关键因素之一。分别从耐旱性、耐阴性和耐寒性对佛甲草(Sedum lineare)、垂盆草(Sedum sar-mentosum)、景天三七(Sedum aizoon)和白景天(Sedum album)4种景天属植物展开了适应性研究。结果发现,耐旱性强弱顺序为佛甲草>景天三七>垂盆草>白景天;耐阴性强弱顺序为垂盆草>景天三七>白景天>佛甲草;耐寒性强弱顺序为白景天>佛甲草>垂盆草>景天三七;综合4种景天属植物的适应性研究,结果表明供试品种均能适应当地气候,可以作为武汉地区屋顶绿化植物材料。
Roof greening was an important measure in improving ecological environment and in the low carbon city construction.Choosing appropriate roof greening plant materials was one of the key factors which affected the ecological quality.The adaptability of four Sedum cultivars（Sedum lineare,Sedum sarmentosum,Sedum aizoon and Sedum album） was studied from the shadow resistance,drought resistance and cold tolerance.The drought resistance order was as follows： Sedum lineare Sedum aizoon〉 Sedum sarmentosum 〉Sedum album.The shade resistance order was as follows： 〉Sedum sarmentosum 〉Sedum aizoon Sedum album Sedum lineare.The cold resistance order was： 〉Sedum album 〉Sedum lineare Sedum sarmentosum Sedum aizoon.In general,Four Sedum cultivars could adapt to local climate,and could be used for roof greening.
