唐宋时期太湖南岸平原区农田水利格局的形成

The Process of the Irrigation Framework Shaping Up in the Southern Part of Taihu Lake in Tang Song Dynasty

唐宋时期在太湖湖流的作用下,太湖南岸形成一条地势较高的滨湖沉积带,吴越时在太湖湖滨开挖溇港,创建湖堤。入宋以后,在太湖南部碟型洼地的平原地形中,产生了横塘纵溇的水利结构?崽劣胱轀鞠嗯浜现饕?是为成功地向太湖排出平原洪涝水,两宋时对横塘纵溇结构的完善主要体现为溇港的设闸与横塘的加筑扑问逼诘?水利建设奠定了后期太湖南岸地区农田水利开发的基本格局。

A sedimentary band was shaping up in the southern part of Taihu Lake by the lake current in Tang-Song dynasty. Hereafter Lou-gangs were ripped up in the lake shore in Wuyue period, at the same time the lake embankment was built up. In Song dynasty an irrigation framework so-called ＂Hengtang-Zonglou was forming in the southern part of Taihu Lake, where the plain topography is the saucer shape. This irrigation framework has the function of easily draining of the stagnant water to Taihu lake. Then by setting up Lock gates in the lougangs and building up more Tangs the irrigation framework was increasingly developmented. The basic pattern of water conservancy facilities that was formed in Tang-Song dynasty established a succeeding irrigation structure in the southern part of Taihu Lake.
