摘　　要：为了解释室内与野外实验中弥散参数依赖于规模的现象,本文分析了垂向非均质含水层中污染质的运移,介绍了宏观弥散及其参数的概念,以实例说明宏观弥散度的物理意义和组成。这些研究将有助于正确恰当地应用水动力弥散方程解决野外问题。In order to explain the phenomenon that dispersion parameters rely on the scales, for experiments both in laboratory and in field, the motion of contaminant in vertical non-homogeneous aquifer is analyzed, the concepts of macrodispersion and its parameters are introduced in this article. The physical meaning and components of macro-dispersivity are expounded with examples. Those researches will be helpful to use equation of hydrodynamic dispersion properly and accurately in solving the field problems.
