基于GIS的饮用水源环境信息系统开发研究

Research on environmental information system of drinking water sources based on GIS

利用组件式GIS建立饮用水源环境信息系统,对水源地的各项指标及相关信息进行监测和预警,对污染源进行分析,能够为灾区水源地的保护和管理提供重要的信息支持,为管理者提供决策依据。以VS.NET为可视化的开发平台,结合MapObjects控件开发饮用水源环境信息系统,着重研究了系统总体结构和系统的功能。饮用水源环境信息系统的建立,实现了水源地的图层管理、数据库操作、可视化评价、统计分析和空间分析等,有利于管理者为保护饮用水源作出决策。

The monitoring and pre-warning on the indexes and related information,and the analysis on pollution sources by information system of drinking water sources based on component-type GIS will provide an important information support for the protection and management of water sources in disaster area and a basis for decision-making.Taking VS.net as visualized development platform and in the combination of MapObjects,we developed the water environmental information system of drinking water.We mainly introduce the general structure and functions of the system.The system has realized image-layer management,data base operation,visualized evaluation,statistics analysis and spatial analysis,which is beneficial to decision-making for drinking water protection.
