摘　　要： 随着我国灾害科学研究的不断深入及经济建设的日益发展 ,从风险角度分析灾害已成为灾害分析的一种新视角 ,它有助于决策者进行灾害管理和制定减灾策略时有针对性地选择最优技术政策 ,防患于未然。雨涝灾害是湖北省最严重的气候灾害之一 ,据统计 ,湖北省平均每年受雨涝危害的农田面积为 80 .6 2万hm2 ,成灾面积为 47.0 7万hm2 ,特别是 80年代以来湖北省工农业生产重地江汉平原和鄂东雨涝事件明显增多 ,严重威胁和制约着我省国民经济持续稳定发展。依据自然灾害风险分析原理 ,在分析湖北省雨涝灾害孕灾环境、致灾因子、承灾体密度和经济发展水平及承灾体的抗灾能力的基础上 ,综合评价了湖北省雨涝灾害风险程度的地域差异 ,以能综合体现风险程度的风险指数作为指标 ,将湖北省雨涝灾害分为极重度、重度、中度和轻度四个风险区 ,并提出了相应的对策措施 。 With the development of disaster research and economy, disaster analyses from a point of risk view have become a new research area, which will help decision makers to choose optimal technical polices to manage disaster and to set up disaster-reduced tactics. Waterlogging is one of the most severe disaster in Hubei province. According to the statistics,the annual average flooded area and of flood-damaged area are 0.806 2 and 0.470 7 miltion hm\+2, respectively. The obvious increase of waterlogging in Jianghan plain and east of Hubei from 1980 to 1999, had badly threatened and restricted sustainable economy develpement in the province.In terms of natural disaster risk analysis rules, the regional difference of waterlogging risk degree is assessed synthetically, based on the analysis of disaster hazard, vulnerability and anti-disaster ability. The risk regionalization of waterlogging in Hubei province is made by using of a categorical index for representing risk degree, including terribly heavy,heavy,middle and light, the four risk regionalization. Some suggestions and measures were proposed,for references of disaster management and disater-alleviated tactics.
