3 500 km shallow seismic profiles are acquired from the nearshore area off the North Fujian for study of the spatial distribution pattern,such as width and depth variations,and vertical reflection characteristics,such as interface reflection and internal boundaries,of the fluvial system prevailed in the Last Glacial Maximum.Based upon the data,we made a systematic investigation of the paleo-river system.Results show that:(1)A paleo-river system occurred in the study area.The distribution of the rivers roughly follows the current submarine topography.One of the paleo-river courses roughly in east-west direction might be from the Minjiang River,another one,which is in north-south direction,might be derived from one of the tributaries of the Yangtze River.(2)The area which is exposed to air in Last Glacial Maximum was flooded by the transgression later on.
