摘要
针对水环境信息的多源、异构、分布式和时效性等特征,研究了基于Geoportal的流域水环境信息共享平台构建技术,同时结合当前水环境管理部门信息存储、管理、使用的现状和面向服务架构(SOA)的设计思想,构建分布式的信息共享平台,实现空间数据、属性数据以及多格式数据的有效集成共享,提供水环境信息的注册、发布、下载和实时收割等功能,并可为流域水环境风险评估与预警提供实时、准确、可靠的数据服务。
A set of techniques were studied for building a Basin Water Environmental Information Sharing Platform based on Geoportal against water environment information featured by muhisource, isomerism, distribution and timeliness. Meanwhile, considering the current situation of information storing, management and use by the water environmental departments, a case of distributed sharing platform was built with the deign idea of service-oriented architecture （SOA）. The platform could realize effective data integration of spatial data, attribute data and other formatted data, have the functions of registration, publishing, downloading and harvesting etc., of water environmental information, and provide a timely, accurate, credible data service for basin water environmental risk assessment and warning.
