| 摘 要： | 本文研究了20种元素在长江武汉段水体中的含量水平,分配特征及其影响因素,对底质粒经,物质组份,元素含量,水力条件,河床状况及悬浮物之间的相互关系作了较深入探讨,认为江段悬浮物及底质主要由上游水土流失形成,因而各元素量基本上是地球化学量。根据形态研究结果,提出了各元素潜在活性序列,指出如水体环境条件特别是 pH 变化可能严重影响水质状况。

| Abstract: | Content levels,distributed features and affecting factors of 20 elements
in the water body of Wuhan reach of Yangtze River have been investigated,and have
had a discussion on the interrelationship in relation to one another of the bed sedi-
ments grain size,the component of substance,elements content,hydraulic condition,bed
form and suspended load.It is concluded that each element content in the suspended
load and bed sediment almost equals to geochemistry content,because the suspended
load and bed sediment mainly comes form erosion loss,A potential active sequence of
elements has presumed according as the results on state of the elements studied,and
indicated that it may seriously affect water quality if the environmental conditions,
particularly pH,in water bodies is changed. |
