【Abstract】 Based on the comprehensive environmental data of Xiamen Harbour and Jiulong River Estuary, this paper briefly describes the formation and evolution of the Jiulong Rlver estuarine shoal, especially those of the estuarine shoal in the channel to the Haichang port of Xiamen. The result shows that the estuarine shoal was formed by the comprehensive effects of such factors as the river runoff, tidal waves, and the convergence of saline and fresh water etc. And the progress of its alluviation and evolution relates directly to the continuous silting up and expansion of the estuarlne sand bar at the Jiyu Islet.更多还原
