对当前全球性海面上升对长江口的影响问题作了定量的探讨，并通过计算长时间序列的验潮资料，得出长江口平均海面的变化大约具有２年的短周期，１０年，１９年的长周期。近７０年来长江口海面的上升速率为０．１８±０．０６ｃｍ／ａ．近４０年海面上升速率为０．２６±０．０７ｃｍ／ａ．
The current global sea rise on the Yangtze Estuary quantitatively discussed the issue, and by calculating the long time series of tide data, the average sea level changes of the Yangtze Estuary about 2 years of short cycle, 10 years and 19 years Long cycle. The rising rate of the sea surface in the Yangtze Estuary in the past 70 years was 0.18 ± 0.06 cm / a. The rate of sea surface rise in the past 40 years was 0.26 ± 0.07 cm / a.
