福建省九龙江、漳江口红树林湿地是我国两处重要的红树林自然保护区。近年来随着地区经济的快速发展，排入海湾河口的重金属污染物迅速增多，大量的污染物汇集于河口海湾区，使得红树林湿地面临着越来越严重的重金属污染物的冲击。本研究以这两处红树林湿地为典型地区，选择七种主要的重金属元素（Fe、Mn、Zn、Pb、Cu、Ni、Cd）为研究对象，采用连续提取法(SEPs:Sequentialextractionprocedures),分析几种重金属元素在红树林湿地沉积物中含量、赋存形态的空间分布规律，及其与沉积物理化性状的关系，探讨重金属污染物在红树林湿地累积、迁移的规律；结合根际模拟试验，探寻红树植物根系行为对...Jiulongjiang estuary mangrove wetland and Zhangjiang estuary mangrove wetland of Fujian province are two of important natural reserves of mangrove in China. In recent years, rapid economic growth and development in the region has led to excessiverelease of heavy metal pollutants into the wetland. The accumulation of contaminants in wetland sediments is likely to pose serious environmental problem...学位：理学博士院系专业：生命科学学院生物学系_生态学学号：B20022601
