长江中下游地区地下水中Mn元素的背景特征及其形成

The Background Characteristics and Formation of Mn Element of Groundwater in the Area of the Middle and Lower Veaches of the Yangfze River

该文论述了长江中下游地区地下水锰元素的背景特征及其与地下水的含水介质成分、上覆岩土性质、氧化还原环境、地下水的迳流条件、地下水及土壤酸碱度的关系。研究结果表明,长江中下游地区地下水中Mn元素含量,在区域上分布特点为江汉平原东部区>长江三角洲南部区>鄱阳湖区。

Based on the study project of groundwater environment in the middle - lower reach area of yangtze River, to describe the background characteristics of Mr in groundwater, composition of the aguiferous media, properties of overlying rock and soil, OXidation and reduction environment, conditions of runoff in ground-waterand acid - alkaline numbers of ground water and soil. The result showed that the distribution of Mr element in groundwater showed as: east part of Jian - Han plain > South part of River Yangtze Delta > Lake Boyang.
