摘要
对桐乡市主要乔木树种按主要干线通道、干线河道、片林(苗圃和桑园)不同功能区、不同器官(根、皮、干、枝和叶)吸收重金属的能力进行了检测。结果表明:树种的不同部位累积重金属的能力,在通道枝、叶>根>皮、干,在河道根>枝、叶>皮、干;从吸收重金属的效益看,通道绿化应选择枝叶比较茂盛的树种,河道绿化应选择根系发达的树种。
Determinations were conducted on heavy metals in different organs of the arbor species in different functional areas of Tongxiang city,Zhejiang province. The results showed that metal accumulation ability of different parts of road trees was ordered by branch and leaf 〉 root 〉 barkand trunk, that of trees along river was： root 〉 leaf and branch 〉 bark and stem. The result indicated that tree species with more branch and leaf shouldselected for afforestation of highway, and that with better root system for river banks.
