Abstract: The quantitative dynamic stratigraphy (QDS) is a new synthetical subject which studies the geologic dynamics, stratigraphy, sedimentology and hydrodynamics of a sedimentary basin by using quantitative mathematical methods, and finally obtains the distribution model of sedimentary facies and strata of the basin. This paper briefly introduces the advancing, theoretical basis and the research methods of the quantitative dynamic stratigraphy, and clarifies its main applications through some practical examples.
