摘　　要：导出了能反映含水层中水—岩间阳离子交换作用的溶质运移方程,并提出了一个新的海水入侵数学模型。模型以交换阳离子Na^+和Ca^(2+)作为模拟因子,考虑了海水入侵过程中水—岩间的Na^+—Ca^(2+)交换,模型用于模拟山东省龙口市黄河营地区的海水入侵,取得了令人满意的结果,从而证明导出的溶质运移方程是正确的,建立的模型是可靠的。A solute transport equation is presented, in which the reaction of ion exchange between water and rock is considered. A new mathematical model of seawater intrusion is also presented. In this model, the exchange cation Na^+ and Ca^(2+) are used as simulated factor and the cation exchange of Na^+- Ca^(2+) between water and rock in aquifer during sea water intrusion is considered. This model is applied to simulate sea water intrusion in Huangheying areas, Longkou City, Shandong Province, the simulated result agree well with the observed data. This demostrate that the presented solute equation is correct and the presented model is reliable.
