Abstract: Coastal area is not only an important center of population, economic and social development of a country but also where natural disaster happens frequently. Based on the typhoon-induced storm surge data from 1989 to 2008, the SRTM3 DEM data, the county district data of 2009, 100 meter grid land-use data of 2005, square kilometer population and GDP data of 2003 of China’s coastal areas, the authors analyze the vulnerability of typhoon-induced storm surge to China’s coastal areas on rising sea level background. The authors use linear regression method to predict sea level rise, use regression method to predict the recurrence period of storm surge and the heights of climax tides, use altitude-area method to mark the area of inundated land, and use Geo-statistics method to show area, population and GDP of each vulnerable district. The results indicate that the Zhujiang River Delta, the Changjiang Delta, alluvial plain north of the Changjiang River in Jiangsu province, Laizhou Bay, Huanghe Delda, Bohai Bay and Liaodong Bay would be seriously influenced by the storm surges. So, much more attention should be paid to these areas in the near further. Agriculture land, water, and construction land are the most likely influenced land use by storm surges.

Key words: sea level rise, China coastal area, typhoon storm surge, vulnerability
