By analyzing and summarizing the recent 10-years' research harvests of sea level change in the east inshore area of China.It was found:(1) in the Chinese sea area,sea level change space-time-diversity was much in evidence.The highest value appeared in August and September,the lowest appeared in February and March.Season difference arrived at 20.75cm.In the Yellow Sea and East Sea,the southeast area was high and the northwest was low.In the South China Sea,sea level of the western area was high and the eastern was low in summer,on the contrary in winter.From Liaoning to Guangxi,the sea level rise velocity was difference,the variety ranged-2.1~10 mm/a.Relative sea level rise rate changed rapidly in some delta area,such as the Changjiang River delta,the Yellow River and the Zhujiang River delta.Into the 2050,in these delta areas sea level may rise separately 980 mm,720 mm and 520 mm.(2) Ground subsidence has been one of important influencing ingredient to relative sea level rising rapidly in the coastal region of China,especially,in some deltas where density of population is great.At the same time,east wind may be boost up the sea level rise velocity in the coastal region of China.(3) It is in August and September that sea level reached the highest value in the coastal region of China and at one time the region was attacked by typhoon.At the function of the typhoon and high sea level together,southeast coastal cities security will be threatened.
