【摘要】 消除交点和半交点周期性变化的影响，自２０世纪７０年代以年来中国黄海沿岸的潮差随年份显著增大，高潮位随之明显地上升，低潮位也呈明显的下降趋势。 属于大陆边缘海域的中国黄海，海平面上升影响的显著性，通过驻波作用明显地表现出来。全球海平面上升引起的陆架浅水区域海底和侧向摩擦作用改变和减小，从而导致入射波、反射波和折射波的传播发生变化，该变化造成潮汐驻波位置（潮无潮点）的移动，由此造成潮差显著变化，涨、落潮时出现提前或滞后的变化。 本文通过对中国黄海近岸长期验潮站年平均潮差、年平均高潮位、年平均低潮位、年平均海平面和主要半日潮潮汐调和常数的分析，得出全球海平面上升已引起中国黄海近岸的潮差明显增大和高潮位显著上升的结论。３０年来，黄海近海的潮差增速７．１ｍｍ／ａ，年平均高潮位升速６．６ｍｍ／ａ，海平面年上升速率为２．１ｍｍ／ａ．海平面上升和浅海潮汐驻波变化在很大程度上加重了中国黄海沿岸的海洋灾害。一些沿海岸段的侵蚀和盐渍加重也是潮差增大和海平面上升共同影响的结果。 为了提高天文潮推算的精度，必须采用最接近推算年份的调和常数进行潮汐推算。更多还原

【Abstract】 The tidal range and the amplitude of main semi-diurnal tide along the western coast of the Yellow Sea have become larger for 30 years, and the high waters have become higher and the low Waters have become lower as well. The effect of mean sea level rise is shown by the standing tide wave in the shallow Water areas of the continental shelf. Mean sea level rise can cause the lateral friction to change remarkably, so that tidal ranges being in endless varieties can be regarded as results of the standing wave produced by the interaction among the advancing wave, reflected wave and refracted wave in the shallow water areas. The fact that the high or low tide hour occurs ahead of or behind the scheduled time also proves the migration of semi-diurnal tidal amphidrome. Mean sea level rise can cause the tidal range to increase probably at a rate of 2 to 3 times that of the global mean sea level rise(10-20mm/a) in the western Yellow Sea. We have to face the fact that the enlarging tidal range and mean sea level rise will cause the Storm surge to become severe and some coasts to become eroded and saline. In order to improve the tide prediction, it is necessary to use new tide constants obtained from the nearest tide data.更多还原
