| Abstract: | Based on regression method,annual sea-level changes at 25 tide stations have been analyzed and calculated. The results show that China coastal sea level goes up in the same way as the global sea level,although the ranges are different in different coast areas. Vertical deformation of modern crust and surface subsidence can greatly influence relative sea-level changes in a certain area and they can control tendency and amplitude of relative sea-level changes within a certain extent. "Greenhouse effect "that has made the world warmer is the main factor to cause the fast rising of relative sea level along China coast. In recent year s,over-extraction of groundwater has made surface subside, which gives a hand to sea-level rise. The fast rising of relative sea level will make the coast's natural environments very complicated. The disasters such as storm surge,coast erosion and sea water intrusion will do great harm to coastal economic development. Therefore,it is very necessary to adopt effective measures to reduce the disasters. |
