摘  要：
利用潍坊市1971-2000年9个气象站逐月冰雹及其灾情信息,根据层次分析、加权综合评价、极差标准归一化等方法,建立影响潍坊市冰雹灾害的主要评估模型,即致灾因子危险性、承灾体易损性和防灾减灾能力,综合各项指标通过ArcGIS9.3平台得到潍坊市冰雹灾害风险区划图。结果表明:潍坊市年均降雹日数随地形高程增加呈增加趋势,冰雹灾害发生的高风险区在该市西部地区,其发生冰雹灾害次数多、抗灾能力弱是该区发生雹害概率高的主要原因,较高风险以上的地区占全市一半以上区域,而低风险区则是位于该市中部偏南地区,这与历史冰雹灾情基本吻合。对潍坊市历史冰雹灾害进行风险评估,旨在为该市防灾减灾提供科学依据。

摘  要：
According to previous studies,among all possible measures to avoid and alleviate natural disaster,it is the simplest and most effective method to improve the natural disaster management level to the risk management level through risk zonation on the basis of the scientific research.The spatial information technology was used for risk assessment on historical hail disaster of Weifang in the study,in order to provide scientific basis on disaster prevention and reduction.Based on the AHP,weighted summation evaluation and range standard normalization methods,the paper built the assessment model of hail disaster in Weifang using the nine weather stations data of month-by-month hail hazard from 1971 to 2000.By indexes integration of the dangers of hazard factors,the vulnerability of hazard-affected body and disaster prevention and mitigation capacity using ArcGIS9.3,hail disaster risk zonation of Weifang was obtained.The results showed that,annual average number of hail days increase with the elevation increases.The highest risk regions mainly distribute in the northwest part of city,attributed to its high incidence and weak capacity for disaster reduction.More than half of the city has a higher risk level and the lowest risk regions are located in the centre,which are basically tallies with the history experimental data of hail disaster.
