According to targets and needs of Nansihu water eco-environment management, we took the advantages that WebGIS serves as an overall solution, combined characteristic of SuperMap IS. net WebGIS service platform and adopted the B/S three-tier distributed architecture to put forward the overall design idea, function structure and structure scheme of Nansihu water eco-environment assessment and management WebGIS, Subsequently, we used the C# programming language to carry out the concrete development job, and figured out a scheme to store and disseminate space data and attributes data. Ultimately, with the aid of SuperMap's large-scale spatial database engine SDX + , the system has realized a lot of functions such as spatial information search, hydrology and water quality information inquiry and statistics f water environment quality assessment, lake eutrophication assessment, embodying the visualization of systems analysis sufficiently. The system has been mainly studied and developed in the technology of lake eco-environment management, and also provided an intuitionistic, universal, convenient and reliable management tool for Nansihu water eco-environment management.%根据南四湖水生态环境管理的目标和需求,利用WebGIS作为系统整体解决方案的优势,结合SuperMapIS.net网络地理信息系统服务平台的特点,采用B/S 3层分布式体系结构,提出了南四湖水生态环境评价与管理信息系统的总体设计思路、功能结构和构建方案.在此基础上采用C#编程语言进行了开发,并采用SuperMap的大型空间数据库引擎SDX+,实现了空间信息查询、水文和水质信息查询与统计、水环境质量现状评价和湖泊富营养化评价等诸多功能,并充分体现系统分析的可视化特点.该系统的研究开发对湖泊水生态环境管理领域进行了尝试和探讨,并为南四湖水生态环境管理提供直观、通用、快捷、可靠的管理工具.
