除长江干流外,江汉平原自古存在众多的支流及湖泊,它们的演变对干流的影响很大。本文立足于方志资料,以江陵县为例对宋元明清时期荆北平原的水系变迁进行探讨。宋元明清时期,荆北平原各县的江、河、湖三者的关系变化纷繁,这种演变既受到自然因素如来水、来沙、河道摆动等变化的影响,也受到人类活动的影响,与荆南平原不同的是,荆北平原的水系演变还直接受到了汉水分流的影响。荆北平原的水系尤以明清以来的变化为著,而且该变化影响至今。 Except for the main stream of the Yangtze River, there are numerous tributaries and lakes in the Jianghan Plain since ancient times, and their evolution has a great influence on the mainstream. Based on the local records, taking Jiangling County as an example, this article discusses the changes of water systems in the Jingbei Plain during the Song, Yuan, Ming and Qing Dynasties. During the Song, Yuan, Ming and Qing Dynasties, the relations among rivers, rivers and lakes in counties in the Jingbei Plain varied greatly. The evolution was affected not only by the changes of natural factors such as incoming water, sand, and river channels, but also by human activities. The difference of Jingnan Plain is that the evolution of the water system in the Jingbei Plains is also directly affected by the Hanjiang River diversion. The water system in the Jingbei Plain is especially the change since Ming and Qing Dynasties, and the change has affected so far.
