Abstract：Paleo-geomorphology is one of key controls on paleo-drainage and depositional systemson.In order to better understand the paleo-drainage system and Source-to-Sink system to provide scientific evidences for predictions of provenance system,deposition system and sand stone distribution,the paleo-geomorphology of the Guantao Formation in East Liaodong area,East Bozhong depression of Bohai bay basin are reconstructed using two methods in this paper.Comparison of paleo-morphological reconstruction and paleo-drainage interpretation with different methods shows that paleo-morphology restoration of deposition area using residual thickness may be used in understanding of paleo-drainage outlines for deposition area only.However,paleogeomorphology restoration for depositional area and erosional areas provides a comprehensive paleo-drainage interpretation for depositional and erosional areas taken as a whole.The integrated paleo-morphology restoration can facilitate the prediction of paleo-drainage distribution in source area of "Source-to-Sink system",and establishment of relationship of paleo-drainage systems from source area to sink area.
