摘　　要： 本文通过对净化塘系统和对照点的水、土和宽叶香蒲组织的分析结果指出:宽叶香蒲具有较强的忍耐、吸收和积累Pb、Zn等重金属的能力。Pb、Zn等重金属在宽叶香蒲体内的积累数量与分布规律是根>地下茎>叶;老地下茎>嫩地下茎;Pb在叶的分布是老叶>成熟叶>嫩叶。在净化塘系统内,各种重金属在宽叶香蒲根部积累比例最大的是Pb,其次是Zn、Cu、Cd、Ni、Mn。 With the analysis of the water, the soil and Typha latifolia′s tissue in the purification pond system and. in the control, this paper indicated that Typha latifolia has an excellent ability in tolerance, absorption and assimilating Pb and Zn. The accumulation and distribution are as follows: The order of heavy metals concentration such as Pb and Zn in different parts of T. latifolia from high to low is (1) root, rhizoma, leaf; (2) elder rhizoma, younger one.Similarly the order of Pb amount in the leaf from high to low is elder, mature, tender, At the purification pond system, the highest accumulation in T.latifolia root is Pb, with Zn, Cu, Cd, Ni and Mn in the decending order.
