Research On Hunan Major Natural Disaster Prevention Capability Evaluation And Prevention System Building

With the increase of major natural and man-made disasters and the aggravating of loss, the natural disaster risk management has become a pressing issue worldwide. As Hunan province is located in the middle of China and the main grain-produce zone, it is a great significance of establishing and improving the prevention system of natural disasters to promote economic developing as well as ensure grain security.This paper based on seriously disaster cases occurred worldwide. Firstly, the basic information regarding foreign natural disaster prevention system is summarized from three aspects of natural disaster legal and regulation system, natural disaster management agencies and natural disaster management mode. Secondly, main disasters and their distribution characteristic including the drought, floods, freezing cold disaster, frozen hail damage, agriculture & forestry biological disaster and geological disaster is analyzed. A prediction about the drought disaster and flood disaster in Hunan province is made. Then, the basic framework of Hunan's natural disaster prevention capability evaluation index building is proposed. The evaluation index system and its weight are set based on AHP method. An evaluation regarding prevention capability of Hunan major disaster is made. At last ,builds major natural disasters prevention systems in Hunan: improves the legal and regulation system of major natural disasters in Hunan, improves management agencies setting of major natural disaster in Hunan, innovates management mode of major natural disasters in Hunan, optimize the prevention mechanism of major natural disaster, optimize the early warning mechanism of major natural disasters in Hunan, optimize emergency rescue mechanism of major natural disaster in Hunan, innovates risk diversification mechanism of major natural disasters in Hunan.
