从河床特性与演变角度评长江口白茆沙浅水航道的整治

白茆沙航道位于长江口南支的进口，是目前长江下游与三角洲诸海港的通海航道。７０年代以来，白茆沙航道发生严重的淤积，严重影响海运。根据地理调查，１１０年历史航道图的比较，以及航道水深的测量，着重研究了白茆沙浅滩与航道的河床演变以及航道淤积的原因，这些研究结果可供白茆沙浅滩与航道整治以及长江下游与三角洲海港建设的参考。

A Review on the Realignment of the Baimaosha Shoal Channel at the Changjiang Estuary from Channel Characteristics and Fluvial Processes

Since Baimaosha navigable channel at the Changjiang Estuary. In 70' serious deposition has happened, which effects severely the ocean shipping in the Lower and Delta Reaches of the Changjiang River. This paper gives some comments on regulation of Baimaosha shoal and its navigable Channel and construction of ports in the Lower and Delta Reaches of the Changjiang River according to the geographic investigation,comparison of thehistorical charts of the last 110 years and measurment of the depth of navigable channel,where sires in laid on the fluvial process of Baimaosha shoal and navigable channel and the reason of deposition. The result of the study provides a reference for the regulation of Baimaosha shoal and its navigation Channel and construction of harbour in the Lower and Delta Reaches of the Changjiang River.
