摘　　要：以类似响应比的生物富集系数作为效应值,利用整合分析,综合定量分析15科45种湿地植物对铬(Cr)、镉(Cd)和铅(Pb)的富集能力。结果显示:总体上,人工湿地植物以禾本科和香蒲科植物为主,且对重金属的富集能力顺序为Cd>Pb>Cr;植物不同器官对各重金属的富集能力存在差异,对Cr的富集能力表现为根>叶>茎,对Cd的富集能力表现为根>茎>叶,对Pb的富集能力表现为叶>茎>根;植物在不同类型人工湿地中富集能力也不相同。In this study, the bioaccumulation coefficients were used as the effect values, and the bioaccumulation abilities of 45 wetland plants in 15 families to chromium(Cr), cadmium(Cd) and lead(Pb) were analyzed. The results showed that, on the whole, the bioaccumulation ability of wetland plants to heavy metals followed the order of Cd>Pb>Cr. Gramineae and Typhaceae plants were widely used in constructed wetlands. The bioaccumulation abilities of different organs of plants to the same heavy metals were different, which were manifested as Cr: root>leaf>stem, Cd: root>stem>leaf, Pb: leaf>stem>root. The accumulation ability of plants in different types of constructed wetlands was also different.
