本文根据50—80年代复测的精密水准成果,分析了长江三角洲及其邻近地区的地壳垂直运动,并与沿海海面变化在同一均衡基准下进行比较。本区近代地壳垂直运动受区域构造控制,形变速率不高,变化平缓,区内海岸带以下降为主。

Based on the relevant data of releveling from 50's to 80's in the century, the crustal vertical movement in the Changjiang River Delta and its adescent area is analysed and compared with the sea level changes along the coast of this area with respect to the same isostatic datum.
