摘要
本文根据国内外对河口划分的定义和划分原则,探讨了将长江澄通河段划归长江河口段的依据,通过分析大量的实测资料后认为,长江澄通河段的河床边界塑造由风暴潮最高潮位控制,其主要水动力因素是潮流,并通过近期的河势分析说明了徐六泾节点控制作用有限,因此澄通河段的整治原则应与河口段相同,即控制和稳定有利河势,扩大泄洪能力,调整改善岸线利用条件,适度圈围滩涂,以满足长江三角洲地区经济社会发展对新的岸线资源和土地资源的迫切需求。
According to the definition and demarcation principle for the estuary,the gist of remaining the Chengtong Reach to the Changjing Estuary was discussed.By analyzing a great deal of measurement data and the river regime,this paper suggested that the figuration of the bed boundary of the Chengtong Reach is controlled by stream surge of the highest tide level,the primary hydrodynamic factor is the tidal current,and the effect of the Xulioujin node control is finite.So the regulation principle of the Chengtong Reach should be the same with the estuary.That is controlling and stabilizing favorableness river regime,enlarging flood carrying capacity,adjusting and improving the utilization conditions of bank line and moderation reclaim wetland,so as to satisfy the impendence requirement of socio-economical development in the Yangtze River Delta for the resources of new bank line and land.
