摘要:
公路沿线由于汽车尾气和扬尘导致重金属污染严重,道路绿化应兼顾植被对重金属污染物的净化作用。选择公路两侧4种树种为研究对象,即海滨木槿(Hibiscus hamabo)、金边胡秃子(Elaeagnus pungens)、山核桃(Carya cathayensis)和中山杉(Taxodium ‘Zhongshansha ’)118,测定其叶际微生物群落结构组成和叶际重金属、根际土壤重金属含量。结果显示,不同植物叶际微生物群落结构和物种组成显著不同;中山杉和海滨木槿具有更高的叶际微生物多样性(PD_whole_tree、Shannon、Simpson),而中山杉叶际微生物的丰富度(OTUs、Chao1)最高;中山杉和金边胡秃子叶片Cr(铬)、Cu(铜)、Zn(锌)、Cd(镉)和Pb(铅)含量较低,而对于植被林下土壤重金属含量,海滨木槿较低,中山杉显著高于其余树种;叶片Cr、Cu、Zn以及重金属总量对叶际微生物群落结构具有显著性影响(P<0.05)。综合以上结果,不同植物对不同重金属元素的净化能力不同,其中中山杉总体上对公路交通扬尘阻隔和净化效果更好。
