The medium-term and the long-term cycles of datum plane are made of symmetry structures by the two hal-f cycles of rising and falling, and the shor-t term cycle of datum plane are divided into two basic types of symmetry and non-symmetry. The characteristics of sediment dynamics and the continued sediment time are discussed through analysis of various cycles of datum plane. By detail study, it is considered that the Muling Formation had undergone three larg-e scale sedimentations f
