The results show that with the sea level rise, amphidromic point in this sea area tends to move to the southeast, and then coastal tidal ranges change present consequently different features ,that is,at the left side and bayhead coast near the amphidromic point they change evidently, and little at the right side and bayhead coast far away from amphidromic point.

将南黄海概化为一等深矩形海域，初步研究了在海平面上升3m 和 5m 条件下该海域旋转潮波系统的演化趋势，继而分析了沿岸潮差变化特征。初步分析研究表明：随着海平面上升，该海域 M2 分潮的无潮点有向东南方向偏移的趋势，受此影响，沿岸潮差呈现不同的变化特征，靠近无潮点的左侧及湾顶海岸变化明显，而远离无潮点的右侧及湾顶海岸则变化不大。
