Physical vulnerability assessment on storm surge disaster in China´s coastal areas from 1990 to 2009

Storm surge disaster is very serious in China´s coastal areas. Firstly, storm surge disaster vulnerability index (Storm Surge Vulnerability Index, SSVI) is built to assess the physical vulnerability of storm surge disasters of China´s coastal provinces by learning form the assessment method of Coastal Vulnerability Index (CVI). Then, the physical vulnerability of storm surge disasters is assessed using additive model and the level of SSVI is divided, according to the storm surge disaster loss data during 1990 to 2009 of eleven provinces in coastal region. The results show that there is a large inter-annual and phase variation of SSVI in eleven provinces of China´s coastal region, and generally the level of SSVI in southeastern provinces is greater than the northern.
