Abstract: In this paper,the integrated analysis of multi-spectral,and multi-temporal remote sensing image data(TM,MSS,NOAA/AVHRR) and geoscience data(geomorphological, hydro-geological,lithofacies,archaeological) have been carried out to identify paleo-coastal lines since the Holocene Epoch in the eastern part of North-China plain. The emphasis of the study is placed on the utilization of Information reflecting spatial distribution of salt groundwater and changes of water chemical components,which are closely related to paleo sea transgression and are reflected by environmental factors such as water,heat,salt,soil and vegetations.Some image processing methods are used,so as to better reflect the combined landscape features of soil salinization-vegetation-landuse-geomorphy.Further,integrated processing for images concentrating thematic informations has effectively enhanced the differences of landscapes,for two sides of transgression boundary in the Holocene Epoch.Finally,supported by GIS,a variety of thematic maps are digitized.On the basis of spatial registration,an integrated dataset is generated and used for synthetical analysis for defining and verifying the paleo-coastal lines.

Key words: Holocene transgression, Remote sensing image processing, Extraction of thematic features
