长江中下游地区地下水中Ni元素的背景特征及其形成

The Background Feature and Formation of Ni Element in Groundwater at the Middle and Lower Reaches of the Yangtze 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Ｎｉ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、迳流条件以及地下水酸碱度的关系。

According to the studying results of national tasking key problems of science and technology,the relation between the forming of the background feature and distribution law of Ni element in groundwater at the middle lower reaches of Yangtze River and the composition of the aquiferous medium in groundwater and condition of runoff,acidity-alkalinity in groundwater is demonstrated in this paper.
