摘要
根据收集到的 2 5个验潮站资料 ,表明近几十年来华南沿海海平面大约平均以1 4 5mm/a的速率上升 ,与全球海平面升高速率 1 5mm/a接近。由各验潮站海平面的升降速率与全球海平面平均升高速率比较 ,得到验潮站所在海岸地壳升降速率在 4 4～- 4 1mm/a之间。其运动方向与由滨海相样品反映的晚更新世及全新世以来的海岸升降趋势大体相同 ,即现今海岸主要为中、晚全新世以来的继承性运动。
Based on the analysis of the information of 25 tide-gauge stations collected in South China coastal area,it is shown that the average rate of sea level rising is around 1 45 mm/a from 1953 to 1992 in this area,which is close to the average rate(1 5 mm/a)of global sea level rising.The crust movement rate range of coast that distributed tide-gauge stations is 4 4～4 1 mm/a by comparing the sea level change rate of each tide gauge station with the average rising rate of global sea level.It is reflected that the present crust movement of coast in this area continued since middle and late Holocene epoch.
