摘　　要：以碳酸盐岩中方解石、白云石和石膏的溶解和沉淀化学反应为基础，阐述了反应模型和水流模型，建立了化学动力学方程－水流方程的关系，并且采用解析法－数值法混合解法求解济南岩溶区的反应－迁移模型。The reaction transportation model is established on basis of dissolution and precipitation reactions of calcite,dolomite and gypsum,the model consists of the reaction model which reveals the reaction processes of compositions as the time goes,the flow model which reveals the flow processes of water in the aquifer and the relation equation of chemical dynamic equation flow equation.The reaction transportation model is verified by the example in Jinan karst area.The reaction model is resolved with analysis method.The transportation model is resolved by the finite element method.The reaction rate constant and the hydraulics paramate are determined
