Coastal storm surge is the most serious disaster and the assessment of regional storm surges economic losses is of great significance for the regional industry economic layout, regional storm surge disaster reduction and prevention. In this paper, Jiangsu coastal zone of the storm surge bearing the loss rate was studied, and with other regions of the comparative analysis. In the study clearly put forward a storm surge of regional ecological environment assessment of the concept of economic losses, using composite index combined with the perception of Coastal storm surge and storm surges economic assessment of the disaster was discussed. The Coastal Zone as an example of Yancheng in Jiangsu a case study is achieved better results. Study found that CIISSEL can be used to better reflect the value of storm surges of regional economic loss situation, the size of D can be the level of refinement of the disaster. It is difficult to determine rates of economic losses of storm surges in the current, but it can be done through test the way to resolve this issue.
