长江新济洲河段的演变及整治设想

Evolution of the Xinjizhou Reach of the Yangtze River and Consideration for Its Regulation

长江新济洲河段为典型的顺直分汊型河段，自上而下依次为新生洲、新济洲、子母洲和潜洲，至今基本上处于自然演变状态．本河段的演变受上游马鞍山河段的影响，同时又影响到南京河段的变化．通过对其历史演变及近期演变进行分析，提出了新济州河势控制初步规划的整治原则及具体河势控制方法，有对大黄洲下段岸线进行平顺抛石护岸和在新生洲洲头实行裹护工程等．

Xinjizhou Reach of the Yangtze River is a typical straight branched reach. Fromupstream to downstream Xinshengzhou Island, Xinjizhou Island, Zimuzhou Island and Qianzhou Is-land are distributed successlvely. Up to now they are basically in the state of natural development.The development of the reach is lnfluenced by Maanshan Reach on upstream, meanwhile it also influ-ences the changes of Nanjing Reach. The regulation principle and specific method of the river be-haviour controlling for Xinjizhou reach at the elementary planning stage are proposed in this paper.
