摘要
在回顾20世纪水文科学发展历程和分析当前面临的挑战和机遇的基础上,提出在数字化的信息时代,必须充分利用数字技术对传统水文进行全面改革,建设数字水文系统,将站点观测的水文数据与数字地球中的有关数据,经过同化整合,产生数字化的、覆盖整个空间(流域或区域)的、多重尺度(时间和空间)的、多种要素的水文数据产品,为经济建设各有关部门和地球科学各有关领域服务。
Based on a review of the development of hydrologic science during the 20^(th) century and the challenge and opportunities in hydrology, a suggestion is made that in the digital information era the traditional hydrology must be reformed by making full use of the digital information techniques. The new hydrologic information system should be a digitized one with both data observed in situs and remote sensing, covering the whole space (watershed or region), crossing a range of scales (temporal and spatial), including various kinds of hydrologic data products,and serving the entire society and relative scientific researches.
