因地球温室效应等原因，据估计下一世纪，全球海平面上升速率将加快3－6倍，海平面上升首先侵袭并淹没海岸带，在地壳沉降带和沿海低洼地区，海平面上升尤其是一个重大的环境问题。天文潮、风暴潮、河口水位都以当地海平面为基底，在其上传播导致多种灾害。它使风暴潮害加剧、 Due to the global warming effect and other factors, it is estimated that the global sea level rise rate will accelerate by 3-6 times in the next century. The sea level rise will first invade and inundate the coast. In the crustal subsidence zone and low-lying coastal areas, sea level rise is especially one Major environmental issues. Astronomical tides, storm surges and estuarine water levels are all based on the local sea level and propagate on them causing a variety of disasters. It aggravates the storm surge,
