This paper studied the geochemical characteristics of sediments since the last deglaciation from the East China Sea (ECS), aiming to reveal records of paleoenvironment and paleoclimate. Based upon analysis of lithology, grain-size, geochemical and mineral compositions, and AMS ¹⁴C dating for Core EC2005,  located in the depocenter of Zhejiang-Fujian mud wedge on the inner shelf of the ECS, some principal results and conclusions are summarized as follows: 1) TiO₂-normalized values of different major elements of the ECS inner shelf sediment have different environmental and climatic significances; 2) the paleoenvironment dramatically changed within the study area since 17.3 ka B.P.; and 3) from the beginning to the end of the last deglaciation, the overall climate changed towards warm and wet.
