Abstract: Based on the analysis of potential hazard of cold(freezing)damage and prevention capability of cold(freezing)damage,according to yearly meteorological data and other socioeconomic data in papaya potential introduction area,an index system for the risk assessment on cold(freezing)damage of papaya introduced was  established Combined with the AHP and entropyweight coefficient method,the indicator weight was determined,and risk assessment model was constructed by using the multiindex comprehensive evaluation method.Then the comprehensive index was calculated and the division map was drawn for the risk analysis and division of cold(freezing)damage of papaya introduction.The results showed that the low risk regions were located in coastal areas with low elevation to the south of Jinjiang because of light disaster causing factors and low but could be great prompted prevention capacity.The medium risk regions were distributed in coastal areas with low elevation from Changle to Quanzhou,and most low elevation areas of Longhai,Changtai and Zhangzhou city,and part areas of Zhangpu,Yunxiao and Zhao′an.Other regions were located at high risk,the high latitude areas were even with higher risk Verified by historical examples,risk assessment results were more consistent with actual situation,therefore,research results have good application,can provide reference for papaya planting pattern and disaster prevention.
