海口湾东部浅滩的发育演变及其机制分析

ANALYSES ON EVOLUTION OF SHOAL IN EAST PARTOF HAIKOU BAY AND ITS MECHANISM

介绍了海口湾东部浅滩的动力特征与发育历史，重点研究了其近年来的演变状况及机制。计算的波浪作用下浅滩的侵蚀与实际地形变化相关不好，表明泥沙来源减少、沉积物的压实作用与浅滩上的人为活动是造成浅滩高程下降的主要因素。

The paper gives an introduction about the hydrodynamic features and the evo-lutionary history of the shoal in the east part of the Haikou Bay, and put the emphasison studing its evolutionary situation and mechanism in recent years. The correlation be-tween the calculated erosion under wave action and the actual topography variation is notgood, showing that the main factors for the fall of the shoal elevation are the decrease ofsand input, sediments self-compaction and human activities.
