摘　　要：采用当前方法设计的统计系统对不同区域的洪水灾害特征进行统计时,所用的时间较长,得到的统计结果误差大,存在统计效率低和统计精准度低的问题。该文提出基于降水大数据的不同区域洪水灾害特征统计系统设计方法,在相关性原则和独立性原则的基础上,构建包括基础功能模块、数据处理模块、信息提取模块和样本管理模块的不同区域洪水灾害特征统计系统框架,利用经验公式法计算洪峰流量的设计净雨历时、降雨历时,设计净雨深和流域平均降雨量,以及洪峰流量,构建SCS产流模型、汇流模型、基流模型、河道演进计算模型,利用上述模型对不同区域洪水灾害的特征进行统计,实现不同区域洪水灾害特征统计系统的设计。When using the statistical system designed by the current method to make statistics on the characteristics of flood disasters in different regions, it takes a long time to get the statistical results with large errors, and there are problems of low statistical efficiency and low statistical accuracy. Based on the principle of correlation and independence, a statistical system framework of flood disaster characteristics in different regions is constructed, which includes basic function module, data processing module, information extraction module and sample management module. The design net rainfall duration of flood peak flow is calculated by empirical formula method Rainfall duration, designed net rainfall depth and average rainfall of the basin, as well as flood peak flow, constructed SCS runoff generation model, confluence model, base flow model and channel evolution calculation model, used the above models to make statistics on the characteristics of flood disasters in different regions, and realized the design of statistical system of flood disaster characteristics in different regions.
