SEDIMENTARY CHARACTERISTICS OF GY07-02 COLUMN AND ENVIRONMENTAL CHANGES OF GAOYOU LAKE
-
摘要: 通过对苏北高邮湖GY07-02柱状样沉积物的含水率、粒度、有机碳、碳酸盐含量等环境替代指标的分析,结合14C年代测定,初步揭示了该地区近1 100年来湖泊沉积特征及环境演化历史,大致可以分为3个阶段:920-980AD,为沼泽沉积环境;980-1240AD,湖泊开始扩张,水位上升;1240AD至今,黄河物质通量显著增加。进一步说明湖泊的演变不仅与黄河南泛夺淮有关,也与人类活动如人口迁移、湖泊周围建闸、围湖造地、富营养化程度加剧等关系密切。Abstract: The work is based on a continuous column GY07-02 taken from the Gaoyou Lake in North Jiangsu Province. Detailed evidence of particle size, water content, organic carbon content and total carbonate content is collected, combining with 14C dating and calibration. The history of environment variations of the Gaoyou Lake since 1100a is reconstructed. During 920-980AD, the study area was a marsh;During 980-1240AD, the lake area was expanded with water level rising;and since 1240AD, the Huanghe River shifted to the south and the Yellow sea invaded the area through the Huanghe River estuary that resulted in the increase in sediments. The changes in lake environment were not only related to the natural environment changes, but also human activities, such as the shifting of Huanghe (Yellow) River channel, construction of dams around the lake, land reclamation and water eutrophication.
