摘　　要：为了解垂直绿化植物叶片对重金属的富集能力,在南京市不同地点及不同月份测定了野外盆栽的爬山虎、多花蔷薇、云南黄馨叶片中Zn、Cu、Pb的含量。结果表明:3种植物叶片对Zn、Cu、Pb均具有一定的富集能力,并依地点和采样时间的不同而差异明显。此外,3种植物叶片对Zn元素富集量的月变化基本一致,即从4月到6月减少,6月到8月增加,8月后开始减少;对Cu元素富集量的月变化总体上看均呈减少趋势。通过综合比较得出,爬山虎叶片对Zn、Cu、Pb具有较强的富集能力。In order to explore the accumulation ability of leaves of three vertical plants to Zn,Cu,Pb,the metal＇s contents in leaves of the three plants（Parthenocissus tricuspidata,Rosa multiflora,Jasminum mesnyi） were determined at different sites and in different months in this paper.The results showed that the three plants could accumulate Zn,Cu,Pb to different extent depending on sites and time.Besides,the dynamics of accumulation quantity of the three vertical plants＇ leaves to Zn were basically consistent,that was the content of Zn decreased from April to June,then went back in the early June,and came down from August;the content of Cu in three species＇ leaves decreased with the passage of time.Finally,through comprehensive analysis it was concluded that Parthenocissus tricuspidata＇s leaves had high accumulation ability to Zn,Cu,Pb.
