Analysis of Coastal Environment Vulnerability Determination Methods

This research wants to reflect the results and methods of pervious researches in natural places and coastal areas and tries to find best method for decision making in coastal areas of Iran. This research has been done by investigating 49 researches about vulnerability which 70% of them were about vulnerability evaluation in coastal areas and 69 researches was about the stresses and 10 researches was about sensitive areas. Among various methods the most useful method is CVI. In this method both variables and stresses are used. This survey also showed that sees level rise is the most used stress and Irregular and scarce rainfall and construction of dams is tow stresses that used only in one research. So stresses that used more than the others are more important. The survey also showed that among sensitivity resources، ecological criteria and economical criteria have the highest frequency. So for calculating sensitivity each sensitivity resources that used more than the others are more important.
