Abstract:

From the records of the tide-guage stations for the past 30 years,sea level rise along the coast of South China is estimated at a rate of 1-1.2mm/a.Sea level changes vary at different section of the coast due to the effects of neotectonic movement: the sea revel rise rate at the Zhujiang Delta reaches 1.9-2.6mm/a,that in eastern coast of Leizhou Peninsula and Hainan Island is 4 mm/a,that in the eastern coast of Guangdong is less than the mean rate (1-1.2 mm/a)or sea level subsides there,and that in distinct sections (for instance,the western coast of the Strait of Taiwan) is farcer and reaches 4 mm/a due to the effects of marine hydrological factors.
