本文运用化学热力学与水文地质系统耦合理论，将太原东山水文地质系统划分成矿物溶解、沉淀各异的区带；通过各区带内的化学—数学与相关分析法的耦合模型，计算出各区带碳酸、硫酸盐岩的综合溶蚀模量；再将综合溶蚀模量和用化学动力学理论确定地下水实际速度的解析解公式与有限单元法耦合，计算确定出各节点的溶蚀速度。从而不仅有效地评价了水文地质系统内的溶蚀特点，还可反映区内地质构造和水文地质条件，以及含水层在倾向方向随埋深增大呈幂函数变化的规律；进而可确定出区内供水、矿井防治水的最佳勘探地段。这些不仅具有一定理论意义，也具有一定的社会和经济效益
In this paper, the coupling theory of chemical thermodynamics and hydrogeology system is used to divide the Taiyuan Dongshan hydrogeological system into zones of different dissolution and sedimentation. Through the coupling model of chemical-mathematics and correlation analysis in each zone, , And the comprehensive dissolution modulus of sulphate rocks. Then, the analytical solution of the integrated dissolution modulus and the actual velocity of groundwater determined by the theory of chemical kinetics is coupled with the finite element method to calculate the dissolution rate of each node. Therefore, not only the characteristics of erosion in the hydrogeological system can be evaluated effectively, but also the geological structure and hydrogeological conditions in the area and the regularity that the aquifer varies in power function in the direction of orientation with increasing depth can be determined. Water, mine prevention and control of water the best exploration area. These not only have certain theoretical significance, but also have certain social and economic benefits
