| 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.

| Abstract: | It is shown that the general trend of sea level change has been subsided in recent 43 a in Qinhuangdao,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. |

| Keywords: | Sea level annual change rate earh crust |
