摘要: 通过对太平湖湖水和沉积物中12种微量元素进行系统研究,分析了湖水中元素的存在形态,不同水期、年份和沿湖流程的变化.揭示了沉积物中元素含量变化的影响因素,元素含量与矿物成分、汇水区岩性的关系以及元素间的相关关系.阐述了湖水与沉积物间元素的迁移转化,富集与分散的特征.

Abstract: The geochemical characteristics of trace elements in water environment in Taiping Lake are studied in a systematic way based on the field investigation and sampling, and the analysis and measurement in the laboratory. The content, form,distribution, varia-tion, effect factors and migration of 12 trace elements Cu,Pb,Zn,Cd,Co,Ni,As Hg,Cr, Mn,Fe and V in lake water and sediments are discussed in detail. The main research re-sults are shown as follows.1. The elements Pb,Zn,Cd,Co,Fe exist,in lake water, in the form of suspension, but Hg exists in the form of solution, the rest elements exist in the form of suspension and solution simultaneously in Taiping Lake water. The less the element contents,the more the precipitation and water quantity.2. The change range of element contents is not large in the lake sediments. There is a close correlation between sediment and rock strata of basin. The trace elenemts are en-riched in clay sediments. There is a close correlation among Fe, Mn,Co,V,Cr,Zn,Ni in sediments under the condition of a = 0.01. 3. There is a same distributive tendency of the trace elements in Taiping Lake water and sediments. Most of trace elements are enriched in the sediments. Trace element Pb is enriched in Taiping Lake water environment.
