| 摘 要： | 研究了南京近郊针、阔叶树种杉木(Cunninghamia lanceolata)、麻栎(Quercus acutissima)对重金属元素铬、铜、镍、铅、锌的吸收和累积规律.研究结果表明,5种重金属元素在2种林分的枯落物层含量均高于灌草层和乔木层各部位,但由于乔木层生物量较大,重金属元索在2种森林生态系统中主要储存在乔...

| Abstract: | The research was carried out in the outskirts of Nanjing city.The aim was to understand the absorption and accumulation of heavy metals(Cr,Cu,Ni,Pb,Zn) by Quercus acutissima and Cunninghamia lanceolata.The results showed that,the content of the 5 heavy metals in forest litter was higher than tree,shrub and grass.Because of the bigger biomass,most of the heavy metals were stored in the tree layer of forest ecosystem,and the storage of heavy metals in Quercus acutissima was more than Cunninghamia lanceolata.T... |
