马驮沙与东兴成陆初考

Prilimilary Research on Formation of Matuosha and Dongxing

从赤乌碑的记载内容和长江中下游江心洲的成形规律入手,探讨马驮沙的成陆过程;根据靖江区域六次大的涨沙历程,探究靖江老岸、沙上、孤北洼地的成陆过程,指出横港并非完全的老岸与沙上的分界线,且横港开挖年代待考;进一步研究东兴地区成陆的相关史料,探讨东兴区域的成陆时间,发现东兴镇的部分区域历史上就在马驮西沙西南地区,东兴的部分区域在明朝已成陆。

Beginning with the records on the Chiwu tablet and the rule of island formation in the the middle and lower reaches of the Yangtze River,this paper probes into the process of the formation of Matuosha.Based on the six expansions of the islands in Jingjiang area,the formation process of the three main areas like Lao’an,Shashang and Gubei is discussed.Then it points out that Henggang is not the entire separatrix between Lao’an and Shashang,and the excavation time of Henggang remains to be confirmed.In addition to this,by examining the research data of land formation time of Dongxing,the location of the area of Dongxing in history is explored.The research shows that some parts of the present Dongxing area was the southwest of Matuo-xisha in history,and part of Dongxing became the land in the Ming Dynasty.
