海平面的变化不仅能引起气候和海况的变化,而且还能因海表负载改变而引起地极的移动。因此,人们试图通过对海平面变化的研究,弄清影响海平面变化的各种因子,逐步掌握其变化规律。这对开发滨海滩涂和提高非周期水位预报精度,甚至获取精确的陆标高程,监测地壳升降,提供地震前兆信息等,都有相当重要的作用。 Changes in sea level can not only cause changes in climate and sea conditions, but also cause the movement of the poles due to changes in the load of the sea surface. Therefore, people try to find out the various factors that affect the sea level change through the study of the sea level change, and gradually grasp the changing rules. This plays an important role in the development of coastal beach cover and in improving the forecast accuracy of aperiodic water level, even obtaining precise elevation of landmarks, monitoring the movements of the earth’s crust, and providing earthquake precursor information.
