摘要:
通过对ZK2孔多环境代用指标的综合分析, 重建了4500年来鄱阳湖湖口地区古环境历史, 研究表明:4500aBP以来, 鄱阳湖湖口地区经历了多次冷暖、干湿交替, 沉积环境也经历了三角洲(3800aBP以前)→古赣江河流(3800-3400aBP)→三角洲(3400-3300aBP)、彭蠡泽开阔湖(3300-2300aBP)→鄱阳湖湖漫滩(2300aBP以来)的变化

Abstract:
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.
Key words:  Poyang Lake  environmental index  environmental evolution
