| 摘 要： | 将河流平衡剖面看成是陆区基准面的观点已受到怀疑，有迹象表明地貌基准面有可能是陆区基准面。河相沉积记录不仅与基准面变化有关，也与源区和流域盆地的许多因素有关，而且河相地层对基准在的响应也比过去理解的复杂得多。上游区由不整合面办公室的河相层序一般难以与海相层序对比。已可相层序模式仍以基准面为支撑理论，层序界面常按财相向盆迁移、复合砂体、古流向偏转和无沉积非作用面等识别，内部仍为三分。目前对可相层序发育

| Abstract: | Regarding the river equilibrium profile as the inland base level is under suspicion.Evidences suggest that the inland base level is much likely to be the geomorphologic base level.Records in fluvial strata relate not only to the change of base level but also to numerous factors of source areas and drainage basins,and the fluvial stratigraphic response to the base level is much more complicated than that was understood ever before.The fluvial sequences bounded by upstream unconformities are generally difficult to correlate with marine sequences.In recent fluvial sequence models,which take the base level as the supporting theory,the boundaries of sequences are usually recognized from the facies drift towards basin,amalgamated sandy body,palaeocurrent deflection and non depositional surface,and the sequence is divided into three parts.The development of a fluvial sequence is explained in an advanced way,but the models are still restrained greatly by time and space studied in practical applications. |
