Abstract: The mud area on the inner shelf of the East China Sea is one of the depocenters since the high sea-level of the Holocene. Sedimentary records since the post-glacial saved in this area provide excellent materials for studying paleoceanographic and paleoenvironmental changes during the Holocene. The Core of MZ02 was recovered from the middle of the mud area(121.89°E,28.17°N,water depth 32 m,core length 35.3 m), and radiocarbon dating, grain-size and foraminiferal analyses were performed for paleoceanographic and paleoenvironmental reconstruction. Results show that the environmental evolution in the Holocene can be divided into 4 stages:the stage I was the coastal inner shelf during 10.8~10.5 cal. kaBP; the stage Ⅱ was the period of the rapid sea-level rise from coastal shelf to the middle shelf during 10.5~8.3 cal. kaBP; the stage Ⅲ was the inner-middle shelf with the Taiwan Warm Current close to the studied area during 8.3~5.2 cal. kaBP; and the stage IV was the inner shelf under the action of the enhanced coastal current. The abundance of warm-water species increased markedly at 8.4 cal. kaBP, suggesting the invasion of the Taiwan Warm Current since then. The lower δ¹⁸O in benthic foraminifera and higher abundance of epifaunal species are thought to be closely related to the enhancement of the coastal current since~4.0 cal. kaBP.
