在全国75卷册的水文资料中,河南省占据14卷册,并负责5卷1册的刊印。目前全省已积累了1919年以来200多兆的水文数据。随着水文资料系列的增加,水文资料在国民经济发展建设的作用越来越重要,使用水文资料的单位也越来越多,水文资料的统计、整理、计算、分析的工作量也越来越大。人工检索耗费了大量的人力财力。随着水文信息化的到来,水文资料的存储介质也发生了根本变化。90年代初全省已全部实现了计算机整编,利用全国水文测站编码和数据库等技术,已将80%以上水文年鉴资料录
Among the 75 volumes of hydrological data in the whole country, Henan occupies 14 volumes and is responsible for the printing of 5 volumes and 1 volume. At present, the province has accumulated more than 200 trillion hydrological data since 1919. With the increase of hydrological data series, the hydrological data plays an increasingly important role in the national economic development and construction. There are also more and more units that use hydrological data. The workload of statistics, sorting, calculation and analysis of hydrological data is also increasing Big. Artificial retrieval consumes a lot of human and financial resources. With the advent of hydrological information, fundamental changes have taken place in the storage media of hydrological data. At the beginning of 1990s, the province has fully realized the computer reorganization. Utilizing the technologies of national hydrological station coding and database, more than 80% of the annual data of hydrological yearbooks
