摘　　要：对阿克苏市5个不同功能区5种常见园林树种叶片的重金属(Pb、Cd、Cu和Zn)含量进行测定分析并探讨其分布特征。结果表明,在所调查的5种园林树种中,法国梧桐叶片的Zn和Pb含量最高,而新疆杨叶片的Cd和Cu含量最高;不同功能区的重金属含量有差异,即工业区树木叶片的Cu和Cd含量最高,交通枢纽带叶片的Zn含量最高,而居民生活区叶片的Pb含量最高;对同一棵树而言,树高2m处的叶片重金属含量大于树高3m和4m处的叶片,其含量随着高度的增加而减少。The contents of several heavy metals（Pb,Cd,Cu and Zn）in the leaves of 5tree species in 5areas with different functions in Aksu were measured.The distribution characters were investigated.The results showed that among the tree species investigated,the leaves of Platanusorientalisexhibited the highest contents of Zn and Pb,and Populus bolleana was found the highest levels of Cd and Cu.Among the areas with different functions,the highest contents of Cu and Cd were found in industrial area,highest amount of Zn was in traffic area,and the highest Pb content in residential area.In an individual,the leaves at 2m height showed higher amount of heavy metal contents than those at 3mand 4m,indicating that the contents of heavy metals decreased with the tree height.
