- Abstract:

Based on the theory of fuzzy mathematics, this article did a research on the vulnerability of hazard-affected bodies of sandstorm disaster in semi-arid grassland area (Xilin Gol League), by means of constructing the evaluation model of vulnerability of sandstorm disaster, and classing the evaluation results. The results showed that the vulnerability of hazard-affected bodies showed gradually reduced tendency during three periods (1981—1990, 1991—2000, 2001—2010) in Xilin Gol League area region. Strong wind days reduce and vegetation coverage increases, the rate of population increase slowed down, and the total number of livestock and overloading rate obtained a certain control, which reduced the bearing pressure disaster to the environment, and enhanced the ability of people and livestock to resist the disaster at the same time. The ability of resisting the disaster and recovery of hazard-affected body were enhanced by the increase of net income of herdsmen, the improvement of medical and health conditions and the increase of traffic facilities. Industrial structure dominated by husbandry has transformed into rational and multivariant one, which is beneficial to economic stability, and enhances the ability of resisting the disaster, and plays a positive role in reducing the vulnerability of hazard-affected bodies. Evaluation results show that the fuzzy mathematics method on steppe sandstorm vulnerability assessment is feasible, but, as a follow-up evaluation results can provide the basis for disaster prevention and mitigation.
