长江中下游地区地下水中Zn元素的背景特征及其形成

Background Feature and Formation of Zn Element in the Groundwater in the Lower Middle ReachesArea of the Yangtae River

根据国家科技攻关研究的结果，论证了长江中下游地区地下水中Ｚｎ元素的背景特征的形成及其分布规律与地下水的含水介质成分、有机质含量、氧化还原环境、地下水迳流条件和地下水酸碱度之间的关系。

It was demonstrated in the essay that the forming of the background feature and distribution law ef Zn element in groundwater in the lower middle reaches area of the Yangtze River.The relation between the composition of aqueous medium,organic matter.content,environment of the oxidation and reduction,conditions of the runoff in groundwater and acidity and alkalinity in groundwater was also discussed.
