摘要
为了研究湖北省大风灾害的特点及风险度，在湖北省1965-2005年的大风灾害调查基础上，分析各地风灾发生频率及造成的人员、财产损失等特征，对各地大风灾害进行影响评估，用受灾人口、成灾面积等指标给出了风灾级别，配合风灾频率确定了风灾影响度，同时根据湖北风灾致灾因子的特点以及对承灾体易损度的分析，利用风灾危险性评价模型给出风灾风险度分析图。结果表明，三峡河谷、江汉平原东部是大风灾害最大风险区所在。
Based on the survey on wind disasters in Hubei Province from 1965 to 2005, through analyzmg some indexes, such as the frequency of wind disaster in each area and the loss of people and property, impact assessments on wind disaster for various areas are made. By means of the indexes as damage-suffering population and disaster-affected area, the grades of wind disaster are given, and in combination with the wind disaster frequency, the influence degrees of wind disasters are determined. According to the characteristics of disaster-inducing factors and the analysis of vulnerability of hazard-bearing bodies, using the hazard assessment model, an analytical chart of wind-disaster risk degree is presented. It is shown that the Three Gorges valley and the eastern Jianghan Plain are the highest-risk areas of wind disaster.
