| 摘 要： | 采用重力活塞取样器在南四湖的独山湖和微山湖分别采取了两个湖底沉积剖面的样品。通过对湖底沉积物高分辨率的粒度、矿物、磁化率、有机碳、色素等环境指标和沉积年代学的综合研究 ,结合研究区的历史文献资料 ,探讨了南四湖形成近 2 5ka以来的水环境演变过程。研究表明 ,南四湖的形成和发展可分为 4个阶段 :初时 ,湖区为古泗水及其沿岸平原 ;西汉时期古泗水中下游段形成分散的湖沼地 ;唐—明代受黄河夺泗入淮和开挖京杭运河等人类活动的影响 ,湖沼扩张、合并 ;清同治 1 1年黄河大决于东明后 ,先后出现的南阳、昭阳、独山、微山四湖合并为统一的南四湖。 |

| Abstract: | In order to probe into the formation cause of the Nansihu Lake and its water Environmental changes,the authors made high resolution research of modern sedimentology on the environmental indexes of magnetic parameters,pigment content,organic matter content and chronology of sediment of Ds core in Dushan Lake and Ws core in Weishan Lake, which are all small lakes lie in Nansihu Lake. Historical documents are also analyzed to reach the conclusion. The authors define that the Nansihu Lake came into being about 2500 a.B.P. and the succession can be divided into four stages.In this evolution process,several scattered lakes merge into a large alke in the east of China. This process is distinctively affected by the overflow of the Yellow River, the extraction of the Grand Canal and other human activities. |
| Keywords: | Nansihu Lake Lake sediment study Evolution of water environment Migration and overflow of the Yellow River Excavation of the Grand Canal |
