基于CUAHSI-HIS的黑河流域水文数据共享发布平台设计与实现

Design and Implementation of Hydrologic Data Sharing for the Heihe River Basin based on the CUAHSI-HIS

水文观测数据是进行流域水文科学及相关科学研究的基础。在回顾国内外水文信息系统及水文数据共享现状的基础上,通过系统收集和整理黑河流域水文观测数据,利用协同促进水文科学发展大学联盟水文信息系统(Consortium of Universities for the Advancement of Hydrologic Sci-ence,Inc.-Hydrologic Information System,CUAHSI-HIS)提供的水文服务器(HydroServer)组件进行了黑河流域水文数据共享发布平台的设计与实现。系统主要采用了观测数据库模型、Web-GIS地图缓存技术和Web Service技术,建立了一个具有水文观测数据检索与浏览、在线服务与分析功能的水文信息共享发布系统。

The hydrologic information is the foundation of the hydrologic researches.At first,this paper reviewed current hydrologic information systems and hydrologic data sharing systems all over the world.Based on the spatial and observation data collected in the Heihe River Basin,a typical inland river basin in the northwest of China,hydrologic data sharing and on-line services were implemented with the help of open source HIS（Hydrologic Information System）from CUAHSI（Consortium of Universities for the Advancement of Hydrologic Science,Inc.）.The specialized HIS for the Heihe River Basin adopted the ODM（Observation Database Model）,WebGIS and Web service and integrated watershed science data from the Heihe River Basin.This established hydrologic information sharing system functions with hydrologic observed data retrieval and browsing,as well as on-line data service and analysis demonstrated by an application case in the Heihe River Basin.
