| 摘 要： | 总结了珠江河口近30年来的变化过程,通过实测资料分析了河口岸线和河势变化特征,探讨了演变原因,认为近30年来,在上游来沙量逐渐减少的条件下,人为活动与径潮流是塑造珠江河口演变的主要动力,近岸浅滩的围垦,深水航道的疏浚,径潮流作用对拦门沙前缘及其主槽的淤积有控制作用,珠江河口已初步形成了岸线平顺,水沙输移顺畅,淤积幅度大幅减缓的态势,有利于维护伶仃洋、黄茅海滩槽基本稳定格局,这对保持河口的水沙平衡和可持续发展,具有良好效果。

| Abstract: | The evolution of the Pearl River Estuary in the past 30 years has been summarized in this paper.The measured data has been used to analyze the features of changes in the shoreline and the rivers and the causes have been discussed.In the past 30 years with the reduced sediment from upstream,the human activities and flows have been the two main driving forces in the changes in the Pearl River Estuary.The reclamation in the shoal close to the shorelines and the dredging in the deep water navigation channel and... |
