According to the relationship between the linking of an interfluve of two Rivers and a network of stream system, this paper analyzes the significance of the canal crossing the watershed between the Qiantangjiang River of Zhejiang and the Xinjiang River of Jiangxi. Then, the physiographic conditions in the selected area are discussed as fallows.1. Topographically, according to the principle that the relief must be low and the selected line must be short, there are there lines to be selected in thewater-shed area between the Qiantangjiang River and the Xinjiang River i.e. the North Line, the Centre Line and the south Line, in which the canal of the North Line will be 45km long and 1025m high, the Centre Line 46km long and 96. 86 mhigh, and the South Line 35km long and 105.8m high.2. According to the engineering geological conditions it seems that the Centre Line is best , the North Line is second, and the South Line is bad3. As for the form of the canal, it should be taken as areservior shape of river channel.For its water sources, apart from using small reservoir built along the canal, it is necessary in addition to develop such as drainage area of the Ji-nshaxi and Shangshangang,or Jiangshangang, and to build or extend some keser-rvoirs, i.e. "Giy1" and " Jixi" , or "Baishuikeng" Reservoirs, and so on.Las, taccording to united scheme of the stair channel of the two rivers, three distinct schemes (including the linking-up opposite each other of both the beginning point and the end poin,tthe contour penetration, and many stairs of the Centre Line).are proposed.It is considered that in them the scheme of linking-up opposite each other of both the beginning point and the end point in the Centre Line is more reasonable through synthetic comparisoni, i.e. investment, moving hereafter, and engineering construction compavisons
