摘要
水环境背景值是水环境地球化学研究的重要内容。本文在研究乌江及赤水河两水系稀土元素水环境背景值的基础上,对两河流稀土元素的分布模式、区域分异规律等环境地球化学特征进行了讨论和总结。
The background value of water environment is the major subject of geochemical research of water environment. On the basis of the research on the background value of water environment of rare elements in drainage systems of Wujiang River and Chishui River, the environmental geochemical features, for example, the distributive model and different reginal regularity of rare earth elements, are discussed and concluded.
