摘要
受超强厄尔尼诺事件影响,2016年长江流域入汛早,暴雨频发,多条河流发生超警戒水位以上洪水,部分支流发生超保证乃至超历史洪水,受灾严重。通过分析洪涝灾情数据,发现此次洪涝灾害特点是灾情总体较重、区域差异较大、山洪灾害严重和城市内涝严重,认为城镇化进程与防洪排涝矛盾突出、中小河流防洪能力偏低、蓄滞洪区安全建设严重滞后、山洪灾害防治工作仍需加强、防洪非工程措施仍不完善等因素是造成此次严重洪涝灾害的主要原因,据此提出相应的对策建议,为今后的防汛减灾工作提供技术支撑。
Affected by the strong El Nino events, Yangtze-River Basin occurred heavy rainstorms frequently and experienced exceed history record flood in 2016. In this papert after analyzing the data of the flood disasters, the characteristics of disasters are summarized which are： the losses caused by the disaster are serious, disaster situation various among regions, flash flood and urban waterlogging in serious conditions. The main causes of severe flood disaster are the rapid urbanization and outdated urban drainage facilities, flood control capacities are lacking in medium and small rivers, vulnerable flash flood prevention, and deficient non-engineering measures. Furthermore, the suggestions are proposed to provide technical support to flood management.
