基于MO的饮用水源保护区划信息系统的设计与初步实现

摘要

目的 为了有效利用水资源信息,实现饮用水源保护区的合理开发、有效保护和科学管理.方法 在对饮用水水源保护区管理工作进行需求分析后,应用组件式地理信息系统(GIS)技术,数据库技术,在Visual Basic平台下,结合专业数学应用模型来建立系统.结果 建立了饮用水水源地信息数据库,并使用MapObject(MO)控件设计并初步开发了饮用水源保护区划分信息系统.结论 系统不仅拥有标准的地理信息操作功能,能很好地进行数据存储、管理和查询,方便地进行数据统计分析,快捷地制作各种专题地图,而且还能对水源地进行划分指导,为饮用水源保护区的管理提供支持.%In order to make use of water resources information effectively,the paper realizes the source water protection areas reasonable development, valid protection and science management. After analysis the need of managing source water protection areas, under the terrace of Visual Basic, we use COMGIS and the database technique combining professional mathematics application model to build up the system. We build up source water database and design and realize the source water protection areas information system by using MO. The system not only can carry on the saving management of data nicely, carry on the data covariance analysis expediently,manufacture various special subject map fast,but also can carry on delineating sources water protection system.
