摘要
1998年开始,黄河水利委员会(以下简称黄委)信息中心先后开发了基于GIS的山东防汛指挥系统、河南黄河工情险情会商系统和黄河下游工情险情会商系统。系统采用Sybase数据库,运行方式为客户机/服务器(C/S)方式。随着黄委“数字黄河”工程建设的开展以及计算机广域网络的扩大、开发技术运行方式的变化和用户的迅速增长,原有系统已不能满足实际需求。2002年开始,黄委基于WebGIS(MapXtreme)和地图服务中间件搭建了黄委地图服务平台。在此平台上,开发完成了Internet/Intranet版本的“黄河下游工情险情会商系统”。此系统可以在不同比例尺电子地图上实现无缝自动漫游(1∶1000000→1∶250000→1∶50000→1∶10000),实现了水文信息查询,防洪工程基础信息查询,防汛部署基本信息查询,实时工情、险情信息上报、查询统计,实时险情信息报警、处理、滚动显示,险情批复以及系统管理维护等功能。平台是按“数字黄河”三层架构搭建的,在平台的基础上对黄河下游工情、险情会商系统进行整合,以满足更广泛的需求。
Since 1998, the Information Center of YRCC has developed several GIS-based software systems, including ＇Shandong Yellow River Flood Control Software System＇, ＇Henan Yellow River Advising System of Engineering-Concerned ＇Information＇, ＇The Lower Yellow River Advising System of Engineering-Concerned Information＇. The systems run on the Client/Sever （C/S） framework and with the Sybase database system. As the implementation of the ＇Digital Yellow River＇ project, along with the expansion of the networks （YRCC WAN）, the increasing of users and the changes of development techniques, the original systems can no longer meet the everincreasing requirement. From 2002, based on WebGIS （MapXtreme） and map mid-ware, the YRCC map service platform was established. On this platform, the ＇The Lower Yellow River Advising System of Engineering- Concerned Information＇ was developed in the Internet/Intranet networks environment. This system can be used with free navigation among the 1：1 000 000, 1：250 000 and 1：50 000 maps without any switch gaps. The users can easily retrieve the hydrologic information, the basic flood control engineering information and flood control deployment information of different resources. The real-time engineering information and flow/flood-concerned information can also be expediently retrieved and be reported to the upper level users. Statistic can be made with the system. The system has the functions of warning, processing and updating displaying of flow/flood-concerned information. The information can be on-line treated and delivered to the relevant departments. And, the system is equipped with running management and maintenance functions. The platform is established with the 3-tier framework. Based on the platform, ＇The Lower Yellow River Advising System of Engineering-Concerned Information＇ was consolidated to meet the increasing demand of users.
