摘要
岩溶动力系统，由于其水化学形成过程的三相不平衡控制，特别是气相ＣＯ２的积极参与和碳酸盐岩特殊的溶解／沉积机理，因而其水化学动态变化规律非常复杂。本文通过对日本Ａｋｉｙｏｓｈｉ－ｄａｉ高原和桂林岩溶试验场的分析，发现岩溶动力系统水化学动态变化规律主要受稀释效应。
The variation of hydrochemistry in karst dyamic system is very complicated due to triphase unequilibrium control of the system on the formation process of hydrochemistry, especially the active involvment of CO 2 gas and peculiar mechanisms of carbonate rock dissolution/precipitation. On the basis of the analysis of the cases on Japanese Akiyoshi dai plateau and the Guilin Karst Experimental Site, it was found that the variation of hydrochemistry in karst dynamic system is mainly controlled by dilution effect, hydrodynamic effect (or called diffusion boundary layer effect) and CO 2 effect.
