| 摘 要： | 射阳湖古时曾是苏北平原上最大的湖泊,湖深且阔,“承受扬州、兴化、高邮、宝应、泰州、盐城诸州邑水,东流入海.”自春秋至北宋,一直是江淮间南北运输通道.1128年黄河夺淮河故道入海后,黄河泛滥,决溢频仍,泥沙大量南下堆积在里下河地区.射阳湖于明崇祯、清乾隆年间被淤积几成平陆,现仅存湖身残迹马家荡和入海河流射阳河.据地学者们从微地貌、钻孔资料、岩性岩相、孢粉、海相生物和微体古生物化石等资料的综合分析,确认射阳湖由全新世高海面时苏北平原上的泻湖演化而成淡水湖泊.

| Abstract: | Sheyang Lake was once in ancientry the largest lake in the north Jiangsu Plain. It was deep and vast, and swarllowed the water drainaging from Yongzou, Xinghua, Gaoyou, Baoying, Taizou, Yaogchen regions and flowed eastward to the Yellow sea. From the Spring and Autumn period to the North Song Dynasty, it was the transport way between the Changjiang River and the Hucihe River. After 1128 A.D.(the Huanghe River flooded southward and deprived the lower Harihc River), the Huanghe River overflowed and bursted frequently, and carried enomous silt and sand southward and deposited in the Lixiahe area with the deposits accummalating, Sheyang Lake almostly changed into a plain during the period from the end of Ming Dynasty to the middle of Qing Dynasty. By now, the remains of Sheyong Lake are only Majadong pool and the sheyongRiver which flows into the Yellow Sea. According to the synthetic analysis based on the micro-landform, drill data.lithological character and lithofacies, sporc-pollen, the fossil of marine organisms and micro-paleorganisms by physiographers, it is affirmed that Sheyong Lake was a fresh water lake developed from a lagoon during Holocene higher sea level period in North Jiangsu plain. |
