摘要
本文研究发现,近43年来秦皇岛沿岸相对海平面变化呈总体下降趋势,其变化速率为-2.1--2.4mm/a,经地壳升降观测资料修正后,确定海平面变化速率为-1.3--1.6mm/a,并分岸段讨论了相对侮平面变化的年速率。由此证明,秦皇岛沿海海岸侵蚀并非由海平面变化引起。预计未来10余年内,海平面变化将不会对海岸带经济发展构成威胁。
It is sthown that the general trend of sea level change has been subsided in recent 43 a in Qin- huangdao , its rate of change is - 2. 1~- - 2. 4mm/a. After correcting the sea level change rate caused by the earth crust rise , subsidence rate is - 1. 3 ~ - 1 . 6mm/a , and based on coast sectioning relative annual change rate is known.
