Abstract: The changes of the plane pattern and the part landform are discussed in this paper. On the basis of the law of the Jiaojiang River's fluvial process, this paper puts up a new pattern for the Jiaojiang River, which fits in with that in 1933. The Jiaozhi Sands in the middle of the Jiaojiang River is unsteady. Since 1960, it has got smaller and smaller. The depth of the harbour is decreased with the Jiazhi Sands shrinking. Now the harbour isn't working well. In this paper, we discuss the possibility of bringing back the Jiazhi Sands, and give some opinions on the channel regulation of the Jiaojiang River.
