摘要
It is important to understand the degree of vulnerability for sustainable development and disaster prevention in coastal areas.Based on index system including six factors and take the storm surge disaster as an example,this paper examines and evaluates the vulnerability degree of the Caofeidian coastal area.Two kinds of determination weight methods are used to compare the reliability of the vulnerability degree.The results show that the vulnerability of the coastal area is gradually reduced from near-shore to inland;serious vulnerable district and relative vulnerable district mainly occur in the nearshore area,from the Jianhe estuary to the Luannan third saltern and from the Gaoshangpu saltern to the Daqinghe saltern.Storm surge disaster risk and land subsidence rate are the two most important indicators among the index system which may affect the vulnerability of the Caofeidian coastal area.
