摘要
在研究相对海面变化时,常常用实测潮位记录来分析相对海面的变化速率。淤泥质海岸的验潮站多设在入海河流的闸下。由于拦门沙发育等因素的影响,闸下测到的潮位不能准确反映低潮时的潮位变化,因此常常采用平均高潮位记录来分析相对海面的变化。本文通过对平均高潮位、平均潮位和平均海平面之间关系的统计分析,得出平均高潮位与平均潮位以及平均海平面变化速率之间的关系。并对江苏沿海6个验潮站33a的潮位记录进行分析,得出江苏沿海此期间的相对海面变化速率为0.29～1.00cm/a。
Tidal gauge records are always used to study the relative sea-level change. For the muddy coast, however, the tidal gauges are usually set on the river mouths and the low tide records are always affected by the sandbars along tidal creeks connected with the river. The low tide records cannot show the actual tidal level of low tide. So, the mean high water levels that are not seriously affected by the sand bars are always used to replace the mean water level to study the regional relative sea-level change. Relationship between mean high tide level and mean tide level, mean tide level and mean sea surface level was studied in the article. And analysis of tidal records from 6 tidal gauge stations from 1968—2000 was made to analyse the relative sea-level change in the recent decades along Jiangsu coast.
