Based on the charateristics of environmental index in respect of granularity, magnetic susceptibility, TOC, δ¹³C and pollen of sediment from ZK2 profile which located in Meijiazhou (116°12'50"E, 29°44'30"N) in Hukou area, Poyang Lake, the paleoenvironmental evolution sequence of Hukou area for over 4500 years has been rebuilt.As a result, the sequence of the paleoenvironmental evolution in Hukou area includes four stages as: (1)4500-3800aBP, it belonged to the stage of hot and wet, inlake delta;(2)3800-3400aBP, cool and dry, river;(3) 3400-2300aBP, climate fluctuated, inlake delta to lake;(4) 2300aBP onwards, cool, floodland.
