摘要:
选择青岛市4条主干道和青岛农业大学校园路段作为具有不同交通流量的采样地区，以草地早熟禾为试材，研究了草地早熟禾的叶片、根和相应的叶面尘、土壤的Pb、Zn、Cu、Cd重金属含量的关系。结果表明：随着距道路边缘水平距离的增加，叶面尘Pb、Zn、Cd含量呈减少趋势，其中Pb含量在0.5 m和10.5 m处差异显著(P<0.05)，Zn、Cd含量在0.5 m处显著高于5.5 m和10.5 m处(P<0.05)；Cu含量随距离的增加无明显变化规律；随水平距离的增加草地早熟禾叶片的Pb、Zn、Cu、Cd含量均呈减少趋势，其中Pb、Zn、Cu含量在0.5 m处与10.5 m处差异显著(P<0.05)；叶面尘Pb、Zn、Cd含量与滞尘量极显著或显著相关；叶片Pb、Zn、Cu含量与滞尘量呈极显著或显著相关关系，Cd含量与滞尘量相关性不明显；不同道路叶面尘Pb、Zn、Cd含量与叶片Pb、Zn、Cd含量极显著或显著相关，叶面尘Pb、Zn、Cu、Cd含量与根重金属含量无显著相关关系；不同道路土壤Pb含量与根Pb含量极显著相关，土壤Cd含量与根Cd含量呈负极显著相关关系；土壤Pb、Zn、Cu、Cd含量与叶片重金属含量无显著相关关系。
Abstract:
Choosing the mainroads of Qingdao and Qingdao Agricultural University campus roads as different region of the different traffic sample,used Poa pretensis as test material,the contents of Pb,Zn,Cu,Cd heavy metals relationship between Poa pretensis leaves,roots and the corresponding of foliar dust and soil were researched.The results showed with the increasing of the horizontal distance from the road edge,the contents of Pb,Zn,Cd heavy metals in foliar dust tended to decrease,there were significant differences between the contents of Pb in 0.5 m and 10.5 m (P<0.05),the contents of Zn,Cd in 0.5 m were significantly higher than 5.5 m and 10.5 m (P<0.05)；the contents of Cu was no significant variation with the increasing of the horizontal distance from the road edge.With the increasing of the horizontal distance from the road edge,the contents of Pb,Zn,Cu,Cd heavy metals in leaves tended to decrease,there were significant differences between the contents of Pb、Zn、Cu in 0.5 m and 10.5 m (P<0.05).The contents of Pb,Zn,Cd between in foliar dust and absorbing dust positively and significantly related,the contents of Pb,Zn,Cu between in leaves and absorbing dust positively and significantly related,while the contents of Cd was no obvious correlation between in leaves and absorbing dust.The contents of Pb,Zn,Cd between in foliar dust and in leaves of different roads positively and significantly related,while there were no obvious correlations of heavy metals between in foliar dust and roots.The contents of Pb between in soil and roots in different roads was positively related,while the contents of Cd between in soil and roots was negatively related；while there were no obvious correlations of heavy metals between in soil and leaves.
