Abstract :
This study is about Environmental Risks Analysis of Helleh protected area of boushehrwith using AHP method. Helleh protected area with extension about 48940.82 hectares, is located at geographic coordinates of ً24، ´38، 50) ( till ( ً23،´ 56، 50)eastern longitude and ( ً24، ´03، 29) till ( ً50، ´16، 29)northern latitude. In this study at the first Delphi method was applied for hazard identification in area. Also according to the field studies, interview with natives and studying the database of helleh, the couple of risks were added to the factors that were identified with Delphi method. Finally 26 risks were identified in two groups that are including natural events and environmental risks. At the next stage, analytical hierarchy process was applied for analysis and priority of identified risks. In this study, the risks were assessed by using of three criteria like severity, probability and vulnerability. With building of raeesali delvari dam on top of the helleh protected area almost 232300 m3 from fresh water of helleh wetland was layed off and only the salinity water of DalakiRiver is streaming to the wetland. This can cause threaten the wetland, fauna and flora of wetland. So the Raeesali delvari dam with weight 0.116 is in preference 1. The rest of risks are in preference 2 till 26. Some ways that have suggested for control the risks are including laying off water pumping from the wetland and regarding to the hunting season, multiplicity and type of legal hunting.
