摘要
The authors have made a further investigation on the tidal-zone paleoforest remains found in the Shenhu bay, Fujian Province. By surveying (scale of 1︰500) andnumbering of the remains, 65 tree trunks were found. They are relatively concentrated in three different regions fromsouth to north. Their growing ages ranged from 45 a to 100 a. 22 ancient trunks?sections with low degree of carbonizationshow that the paleoforest was composed of Keteleeria Carr., Morus L. and Gleditsia L. 14C dating shows that thepaleoforest was living in 9 420—6760 aBP. Later it stoppeddeveloping and was buried by the alluvial aggradation caused by the sea level rise.
