【摘要】 研制开发灌区管理信息系统，实现灌区管理工作的微机化，是推动我国灌区管理工作现代化和规范化的重要措施。随着信息技术的迅速发展，信息处理方式正逐步由手工转向计算机，灌区管理工作对信息传输速度和可靠性也提出了更高的要求，建设高效、可靠的以计算机为支持的灌区信息系统已成为发展的必要需求。 本文结合江苏省洪金灌区的实际，利用GIS的空间信息管理和分析的功能，将已成熟的图形技术与数据库技术揉合在一起，建立了具有可视化的灌区管理信息系统。 灌区管理信息系统包括灌区信息管理子系统、灌区地理信息子系统和用水管理决策子系统三部分，其中前两部分内容为本文研究内容。 整个系统采用windows操作系统，以关系型数据库软件Visual FoxPro7.0作为系统开发平台，开发出数据维护、查询、数据分析统计、打印报表、系统维护和系统帮助六大功能模块；系统利用地理信息系统(GIS)工具软件MapInfo公司提供的MapX控件，将GIS功能模块嵌入面向对象的开发工具VFP7.0开发系统中，实现了地理信息系统的查询功能。 灌区管理信息系统的空间数据和属性数据采用了分开管理的方式，空间数据用文件系统管理，属性数据采用关系数据库管理。通过建立唯一的ID号进行数据联接，将图形与数据库进行关联，实现属性到图形或图形到属性的双向查询。更多还原

【Abstract】 Development of MIS for irrigation district and realizing the computerization of the irrigation district management are important measures of making the management of our country’s irrigation district more modernized and standardized.With the rapid development of the information technology, the way of processing information is being turned to the computer by hand progressively. The irrigation district management has put forward higher request to the transmission speed and dependability of the information. Establishing the high-efficient and reliable MIS for irrigation district depending on the computer has become the essential demand of social development.According to the reality of Hongjin Irrigation District of Jiangsu Province, the ripe figure technology and the database technology are mixed to be the visual MIS for irrigation district by GIS function of managing and analysing the space information in this text.The MIS for irrigation district includes the information management subsystem, geographical information subsystem and subsystem of administrative decision of water. The first two parts are the study content in this text.The whole system adopts Windows operating system with Visual FoxPro7.0 as systematic developing platforms.It includes data maintenance, data searching ,data statistical analysis, report printing,the maintenance and help file of application system.The VFP 7.0 developing system which is a object-oriented database language is embeded by GIS’s function with MapX control of the MapInfo company. So the system have realized the inquiry function of GIS. The spatial-data and attribute-data of the MIS for irrigation district have adopted the way of separating management. The spatial-data is used as the system management of the file . The attribute-data exists in relational database. The figure and database are related through the only ED number to realize two-way inquiry.更多还原
