摘　　要：近３０年验潮资料的年变速率的估算结果表明，华南沿海平均以１～１．２ｍｍ／ａ速率抬升．新构造运动使各个不同岸段相对的海平面变动有如下差异：珠江三角洲和雷琼地区东海岸的海平面抬升速率明显超过１ｍｍ／ａ，闽东、粤东沿海则小于１ｍｍ／ａ，甚至呈下降趋势．局部岸段（如台湾海峡西岸）因海洋水文影响其上升速率也较大．rom the records of the tide-guage stations for the past 30 years, sea level rise along the coast of South China is estimated at a rate of 1- 1. 2mm/a. Sea level changes vary at different section of the coast due to the effects of neotectonic movement: the sea revel rise rate at the Zhujiang Delta reaches 1. 9-2. 6mm/a, that in eastern coast of Leizhou Peninsula and Hainan Island is 4 mm/a, that in the eastern coast of Guangdong is less than the mean rate (1 - 1. 2 mm / a )or sea level subsides there, and that in distinct sections (for instance, the western coast of the Strait of Taiwan) is farcer and reaches 4 mm/a due to the effects of marine hydrological factors.
