| 摘 要： | 以升金湖湖泊湿地为研究对象,对其典型剖面沉积物柱状样以5厘米级间距采样,在多元统计分析基础上,结合ICP数据对其进行高分辨率元素地球化学特征解析,以获取现代沉积记录及其与流域环境变化的关系。结果表明,主成分分析提取的第一主成分有较高的代表性;聚类分析将元素按造岩、迁移累积型、强烈迁移型元素归为三类;大多数金属元素之间存在着显著相关性。

| Abstract: | Columnar sedi ments from Shengjinhu Lake are established and sub-samples are taken at 5cm intervals.High resolution geochemistry records of environment are abstracted based on the ICP and magnetic susceptibility is analyzed to infer the relation of sediments and its drainage area.The results show that there are five climate phase and multivariate statistical analysis indicating significant correlation among most metallic elements. |
