在详细研究东太湖Ｅ２孔全新世沉积基础上，总结和归纳了水下河道的沉积特征和相组合规律。识别出高湖面型和低湖面型两种沉积层序。划分了东太湖晚更新世末以来环境演变阶段：１）１５８８５—６５７５ａＢ．Ｐ．冲积黄土基础上发育而成的古河道；２）６５７５—５８００ａＢ．Ｐ．高湖面时期水下河道沉积环境；３）５８００ａＢ．Ｐ．后，演化为低湖面型水下河道，并逐渐淤积形成开敞湖缘环境。结合西太湖Ｗ１孔沉积特征和层位对比分析，进而讨论了环境演变的阶段性与中国东部全新世海面升降变化的关系。
Based on the detailed study of the Holocene sediment deposition in E2 of the East Taihu Lake, the sedimentary characteristics and the law of phase combination of underwater channels are summarized and summarized. Identify two types of sedimentary sequences of high lake and low lake. The stage of environmental evolution of East Taihu Lake since the end of Late Pleistocene is divided into 1) 15885-6575aB. P. Alluvial loess developed on the basis of the ancient river; 2) 6575-5800aB. P. Sedimentary environment of underwater channel during high lake; 3) 5800aB. P. After that, it evolved into a low lake-type underwater channel and gradually silted to form an open lagoon environment. Based on the sedimentary characteristics and horizon comparison of the W1 pore in the West Taihu Lake, the relationship between the stage of environmental evolution and the sea level rise and fall of the Holocene in eastern China is also discussed.
