摘　　要：水文特征值统计工作是水文年鉴编制工作的重要组成部分,如何高效地统计水文特征值是工作中的难点。针对此问题,笔者提出一种水文特征值统计查询系统。该系统摒弃了传统的人工统计方式,设计了特征值自动统计查询方式,预设好数据源和必要参数之后,便可以选择需要计算的水文要素自动开始计算,无需人工二次调整数据,消除了因人工处理数据所带来的计算误差,提高了水文特征值统计工作的效率。同时,该系统采用标准数据格式,能够直接与南方片数据库及其他水文整编系统进行数据同步,无需将数据再导入其他系统中,为后续开展水文年鉴编制工作提供了便利。The statistical work of hydrological characteristic values is an important part of the compilation of hydrological Yearbook.How to count hydrological characteristic values efficiently is a difficulty in the work.To solve this problem,the author proposes a hydrological eigenvalue statistical query system.The system abandons the traditional manual statistical method and designs the automatic statistical query method of characteristic value.After the data source and necessary parameters are preset,the hydrological elements to be calculated can be selected to start the calculation automatically without manual secondary adjustment of data,which eliminates the calculation error caused by manual data processing and improves the efficiency of hydrological characteristic value statistics.At the same time,the system adopts standard data format,and can synchronize data directly with nanfangpian system and other hydrologic reorganization systems,without having to export the data into files and import it into other systems,it provides convenience for the preparation of follow-up hydrological almanac.
