近20年来,现代信息技术在水文学中的应用有了长足的发展,特别是近几年来,3S技术及ANN技术与水文模型的整合研究从技术上变得切实可行,从而为水文学的研究开创了新的研究领域。本文主要从RS、GIS、GPS及ANN技术四个方面论述了现代信息技术在水文领域包括防汛抗旱、水环境生态保护、水土保持及水文预报等方面的研究及应用现状。
In the recent 20 years, the application of modern information technology in hydrology has made considerable progress. Especially in recent years, the integration of 3S technology with ANN technology and hydrological model has become technically feasible, Create a new research area. This paper mainly discusses the current status of research and application of modern information technology in the field of hydrology, including flood control and drought relief, environmental protection of water environment, soil and water conservation and hydrological forecast from four aspects of RS, GIS, GPS and ANN.
