英文摘要 | 红树林是位于热带、亚热带潮间带的高生产力生态系统,是陆源重金属污染物入海的缓冲带。红树林增加了水体溶解性有机物(Dissolvedorganicmatters,DOM)和沉积物有机质的含量,对红树林湿地重金属源-汇效应产生深刻的影响。解析重金属在红树林湿地中迁移转化途径、关键限制性因子,以及红树植物对重金属的抗性,对于阐明重金属区域迁移和毒性有着重要的生态学意义。本研究针对红树林广泛分布的重金属污染物Cu和Cd,选择常见的红树植物秋茄(Kandeliaobovata)为研究对象,以重金属迁移的关键区域——根际区域为切入点,以施加Cu(0、30、60mg.kg-1)和Cd(0、0.5、1.0、2...; Mangrove forests are well known highly productive ecosystem in coastline and support numerous ecosystem services including dissolved organic matters supplying and heavy metal buffering. Under standing the fate of heavy metals transportation and their key limited factors in mangrove wetland is critical for pollution assessment and ecosystem management.
