Abstract

Abstract

Through densified surface sampling of foraminifer a and accurate elevation measurement along three transectlines in open-coast tidal sal-tmarsh of Jianchuan,particular sal-tmarsh foraminifera assemblages were found. The sal-tmarsh foraminifera assemblages are distributed in well-defined vertical zonations with respect to elevation and closely parallel marsh floral zonations.At the top of the vertical zonation all foraminifera disappear abruptly which are accurately located at the highest high water datum.This distribution pattern can be used to relocate the former sea levels accurately(to an accur acy of within ±5 cm).A modern regional criterion of foraminifera for relocating the former sea levels in high resolution in our country is provided,and deficiencies of studying the vertical zonation only in sheltered coast sal-tmarsh abroad are filled up.
