椒江演变与整治浅析

Understanding Channel Regulation of the Jiaojiang River

本文对椒江平面形态和局部地貌的变化进行了分析,根据椒江本身的河床演变规律,结合1933年的河床形态进行了河势规划;椒江中段的葮芷心滩变化异常,从六十年代以来越来越小并向上游萎缩,由此造成了港区水深不足的严重后果,因此,本文对它进行了分析,并就恢复葮芷心滩的可能性进行了论述,同时提出了一些对椒江整治的看法。

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.
