多孔介质渗透系数的空间尺度问题是一个与地下流体运动和溶质运移的数值模拟密切相关的应用性课题，广泛的应用需求和新的计算方法使其成为近年的热门课题之一。它涉及到相互联系的两个方面：①非均质介质场渗透系数空间尺度行为的分析与模拟；②将局部测量尺度下的试验参数转化为数值模拟网格尺度下的参数输入值的升尺度（ｕｐｓｃａｌｉｎｇ）方法和计算模型。首先介绍了该课题在概念上的拓展及其物理含义，进而以方法为主线，对这一领域具有代表性的研究成果进行了分类和评述，讨论了该课题的研究对地下水流和溶质运移的模拟分析乃至整个多孔介质流体运动研究的意义。
The problem of spatial scale of porous media permeability coefficient is an applied subject which is closely related to the numerical simulation of subsurface fluid movement and solute transport. Extensive application requirements and new calculation methods have made it one of the hot topics in recent years. It involves two aspects of interrelationship: ①the analysis and simulation of the spatial scale behavior of the field permeability coefficient in heterogeneous media; ②the test parameters under the local measurement scale are transformed into the scale-up of the input value of the parameter under the grid scale of numerical simulation Upscaling methods and computational models. First of all, it introduces the conceptual development and the physical meaning of this subject. Then, taking the method as the main line, the paper presents a classification and review of the representative research results in this field. The study on this topic discusses the influence of groundwater flow and solute transport The simulation analysis and even the whole porous media fluid movement significance.
