摘要
Core MD06-3040 was taken from the inner-shelf mud area off the Zhe-Min coast of the East China Sea (27°43. 3663’N, 121°46. 8822’E, water depth 47 m , core length 19. 36 m ). Holocene paleoenvironmental changes since 10. 6 cal. kaBP have been discussed by applying the benthic foraminiferal assemblages and abundances of different ecological groups (infaunal, epifaunal, inner-shelf, middle-outer shelf, Globigerina bulloides, Globigerinoides ruber) as well as foraminiferal isotopic records. The results show paleoenvironmental changes with a rapid sea-level rise during the early Holocene from the inner inner-shelf (10. 6～9.9 cal. ka B.P.); outer inner-shelf (9.9～8.1 cal. ka B.P.) to the middle-shelf (7.7～7.2 cal. ka B.P.) with the highest sea-level.
