| 摘要: |
| 射阳湖是苏北历史上著名的大湖。早全新世因受海侵影响,本区是里下河浅水海湾的一部分;中全新世时,由于西冈等岸外砂堤的形成,本区成为古泻湖,后因海岸东迁,淡水冲灌,古泻湖逐渐演变为淡水湖。1128年黄河夺淮后,大量泥沙进入湖区,湖区淤积迅速,成为沼泽型湖泊,加之人类活动因素的显著影响,射阳湖逐渐演变为里下河平原的一部分。 |

| Abstract: |
| Sheyang Lake was a famous large lake in North Jiangsu in historical period. During the early Holocene, it was transgressed and reduced into a part of Lixahe bay. During the middle Holocene, an old lagoon was formed as the result of the formation of offshores. Later,due to eastward movement of the coastline and flushing action of freshwater, the old lagoon turned into a freshwater lake gradually. As the Yellow River captured the Huaihe River in 1128, a great quantity of sand was carried into the lake and piled up there swiftly. A lot of marshlands were formed in the lake. In addition to man's remarkable influence, it became a part of the Lixiahe Plain. |
