Abstract:

Based on the data of natural disasters of Shaanxi Province from 2009 to 2015, this paper analyzed the spatial and temporal characteristics of natural disasters in this area and evaluated their vulnerability with the combination of mathematical statistical analysis. The results show that the affected population and the affected area of crops are the direct manifestation of the vulnerability of natural disasters. The direct economic loss caused by disasters is the indirect manifestation of the vulnerability of natural disasters. The vulnerability of natural disasters in Shaanxi Province has obvious spatial and temporal distribution differences. The areas with high vulnerability to natural disasters are mainly distributed in the eastern region, while Xi'an and Tongchuan city in the midland are low vulnerability areas. The research provides the decisionmaking basis for the department of disaster prevention and prediction.

Key words: natural disaster, Shaanxi Province, vulnerability research
