流域水文信息系统研究与实践综述

流域水文信息系统是地理信息系统、互联网和数据库等技术与水文学研究的结合,集成观测和环境信息的水文信息系统已经成为“数字地球”技术在流域科学方面的重要应用。研究回顾了流域科学的研究方法、发展现状和技术背景,提出当前流域科学研究迫切需要建立水文信息系统,而水文信息系统的重点任务是流域数据建模与数据共享服务。针对目前Arc Hydro水文地理数据模型和开源“协同促进水文科学发展大学联盟”--水文信息系统(CUAHSI\|HIS)的研究进展,提出了一个适合于黑河流域的在线流域水文信息系统设计即“数字黑河”在线门户,集成流域地理数据、观测数据和数据共享服务于一体的流域水文信息系统将有效推动流域科学各方面的研究。

A Review on Research and Practice for Hydrological Information System

This paper reviews the methods,state of the art and technical background of watershed science research and puts forward the current watershed research urgently needs watershed hydrology information system,and the hydrological information system focused on watershed data modeling and data sharing services.Hydrological information system is a combination of technologies geographic information systems,internet,database and hydrology research.Watershed information infrastructure for integrated observation and environmental information has become the important applications of “Digital Earth” in watershed science.Based on the latest progress of Arc Hydro geographic data model and open source hydrological information system have developed by Consortium of Universities for the Advancement of Hydrologic Science,Inc.(CUAHSI-HIS),this study proposes a function design for hydrology information systems as online portal of digital Heihe,which is suitable for typical inland river basin-the Heihe River Basin in Norwhwest China.Integrated watershed geographic data,observational data and data sharing services in a hydrological information system will be effective in promoting all aspects of watershed science research.
