福建马坑矿区地下水化学成分的变化特征研究

On the Behaviors of the Groundwater Chemistry Component in the Makeng Minefield of Fujian Province

地下水在含水层中运移,不断与其含水介质发生水岩作用,溶解介质中化学元素。在地下水运移过程中,地下水的化学成分与含量不断发生变化。影响矿区地下水化学成分的主要因素有含水层的岩石组合、矿物的溶解度、地下水的径流特点、混合作用及人为作用等。

The migration of the underground water in the water-bearing layers originates the water-rock interaction with the water-bearing media of the underground water and results in the dissolution of the chemical elements from the water-bearing medium. The chemical composition and the contents of underground water have a continuous variation during the movement of the underground water. The principal factors, which have an influence on the groundwater chemistry ingredient, are the rock association and the mineral solubility in the water bearing layers, the runoff flow of the groundwater, the mixing action and artificial influences.
