摘　　要：文章回顾了有关单个粗糙裂隙中水流和溶质运移的理论、实验研究和数值模拟的成果,重点评述了对裂隙结构面粗糙度的分形特征、粗糙裂隙中描述水流的模型和溶质运移的弥散系数和穿透曲线,并对反映单个粗糙裂隙中水流特征的“局部立方定理“适用条件和溶质运移所呈现的“非费克”运移机理作了初步分析,在此基础上探讨了今后的研究趋势。The theories about the roughness, flow and solute transport in a single rough fracture as well as the achievements in laboratory study and numerical simulation are review, ed. Emphasis is put on the fractal dimension of fracture surfaces, flow models, the dispersion coefficient and the breakthrough curve of solute transport. The conditions for application of the ＂local cubic law＂ in flow study and the ＂non-Fickian＂ behavior in solute transport are analyzed. Future research tendencies are discussed.
