GEOCHEMICAL RECORDS OF ENVIRONMENTAL CHANGES IN THE GAOYOU LAKE AND THEIR RESPONSE TO HUMAN ACTIVITIES
-
摘要: 通过对高邮湖钻孔沉积物粒度、沉积速率和地球化学元素等指标的分析,结合高邮湖地区的历史文献记录,探讨了高邮湖近现代时期环境变迁及其对区域重大事件和人类活动的响应。研究结果表明:高邮湖沉积物重金属元素近300年来呈现随深度减小逐渐富集的趋势,区域大事件如黄河改道等是导致元素含量变化的主要原因。而影响元素含量异常波动的人为因素包括为保运河修建高家堰大堤以及清朝修改赋役制度导致人口增长等。近百年来高邮湖沉积物中重金属元素含量的变化主要与人口数量、人类活动方式及强度的改变相关。Abstract: Based on the parameters of the core sediments taken from the Gaoyou Lake, such as grain-size, sedimention rate and contents of geochemical elements, environmental changes during the modern period and their response to human activities and regional events were studied with reference to historical records. It is concluded that the contents of heavy metals increased with the decrease in water depth of the lake in the recent 300 years. The great regional events, such as the northward shift of the Yellow River contributed greatly to the changes in the contents of heavy metal elements. The human factors, which lead to the abnormal fluctuation of the contents of heavy metal elements, include the construction of Gaojia Levee along the Grand Canal for the purpose of shipping, and the significant increase in population owing to the changes of the tax system in the Qin Dynasty. However, the increase in the heavy metals in the recent century is mainly due to the increase in population and the intensification of human activities.
