摘　　要：对裂隙介质中溶质运移的基本规律和数学模型进行了初步探讨:①等效连续介质模型将裂隙中溶质浓度等效平均到整个裂隙介质;②离散裂隙网络模型建立裂隙个体中水流、溶质运移方程,组合求解;③双重连续介质模型对裂隙和基质分别建立水流、溶质运移数学模型求解;④离散裂隙网络-连续介质耦合模型综合了等效连续介质模型和离散裂隙网络模型的优点;⑤随机模型采用随机理论方法;⑥黑箱模型通过研究溶质运移过程的综合效应预测或反求输出或输入信息。通过对目前各种数学模型的分析和比较,为求解具体问题、选取合理的数学模型提供了参考依据。Various mathematical models and essential rules of solute transport in fractured rock system are discussed.. ①the equivalent continuum model,which equivalently distributes the concentration to the whole fractured rock system;②the discrete fracture network model founded by combining the equations of flow and solute transport in every single fractured masses; ③the dual-porosity model, which establishes respective solute transport models in fractured masses and rock masses④the continuum- discrete coupled model synthesizing the merits of equivalent continuum and discrete fracture network; ⑤adopted stochastic theory,which is suitable to the fact, but is still in the stage of theory;⑥the black box model which forecasts and draws the input or output information, by researching the synthetical effect in the progress of solute transport. Through analyzing and comparing the present mathematical models, it provides reference foundation for selecting rational mathematical models to solve concrete problems.
