人类活动对射阳湖的影响

摘要:
本文通过对众多历史文献和地方志资料的分析来研究人类活动对射阳湖演变的影响.结果表明,秦汉至南宋时期,范公堤、运河对射阳湖由古湖向淡水湖的演变影响很大,其中以范公堤尤甚.由于运河决堤次数少,河流堆积于湖区的泥沙量有限,对射阳湖的淤积作用不大;围湖造田对射阳湖的影响也不大,因此古射阳湖的面积还很大.黄河大规模夺淮的700多年间,尤其是明嘉隆以后射阳湖接受了大量黄河所携泥沙的沉积,不断缩小.运堤与湖堤的修建,使射阳湖洪患不绝,填淤加速.开挖河道宣泄内水,以及围湖造田等也使射阳湖日益萎缩,走向分化、解体,至清末射阳湖已成了一个长条状的河道型湖泊,大部分地区已被淤为荡滩沼泽或者被开垦为农田.

Abstract:
In this paper, many historical documents and local chronicles were analyzed to investigate the effects of human activities on evolut ions of Sheyang Lake, the results show ed that during the period from the Qin-Han Dy nasty to South Song Dynasty, the Fan'gong dike and the canals heavily affected the evolution of Shey ang Lake from lagoon to freshw ater lake, especially the Fan' gong dike.However, there were a few times of the canal dike bursting, resulting some silt brought by the river in the lake region that it did not heavily af fect the Sheyang Lake.Similarly, Reclaimation from lakes was minor, therefore the area of Sheyang Lake remained unchanged. In the past 700 years or so, the Huang he River Rad had captured Huaihe River for many times, especially after Jia-Long of the Ming Dynasty, the Sheyang Lake reduced extensively because it received a great quantity of silt which was brought in by Huang he River.As a result of the dike-const ruction of the canal and lakes, Sheyang Lake had frequent flood disasters which resulted in the acceleration of siltation.Channel dredging and reclamation around the lake made Sheyang Lake shrunk, disintegrated, and turned into a long strip one, most of which became marsh or farmland by the end of the Qing Dynasty.
Key words:  Sheyang Lake  Fan'gong dike  reclamation
