【摘要】 本文全面论述了灌区对于我国国民经济及农业可持续发展的重要意义以及加强灌区地下水动态管理在我国灌区发展中的重要作用，并深入分析了灌区地下水动态信息管理的国内外研究现状，在此基础上确定了符合灌区地下水动态实际管理工作的系统研究内容，制定了灌区地下水动态信息管理系统的系统结构和功能，按照信息系统理论和软件工程方法，综合采用先进的计算机技术、数据库管理技术，研制出灌区地下水动态信息管理系统（GDIMS），实现了用计算机管理灌区地下水动态资料，大大地提高了灌区地下水动态信息管理的现代化水平。灌区地下水动态信息管理系统由灌区概况、资料录入、信息查询、图形绘制、报表输出、动态预测、系统维护、帮助、退出九个功能模块组成，采用面向对象的程序设计语言— VISUAL FOXPRO 6.0开发研制。系统的主控功能模块采用下拉式菜单来实现，利用多级菜单进行各层次的控制调用。整个系统的响应速度快，操作简便实用，用户界面友好、数据处理功能齐全，具有较强的实用性、先进性和可移植性。灌区地下水动态信息管理系统建立了灌区地下水动态资料的信息库，提供了多种信息查询方式和全面的数据管理功能，并对地下水动态进行了预测，为灌区水资源管理部门提供辅助决策的必要信息。本系统的开发和研制，不仅为灌区水资源评价和利用、规划等工作奠定了良好的数据基础，而且也为实现灌区地下水动态信息管理的计算机化、规范化、网络化和实现灌区信息资源的共享奠定了基础，对推动灌区的发展，进而推动整个国民经济的发展有着重要的作用。更多还原

【Abstract】 Based on the discussion about the signification of irrigation districts for national economic and sustainable development of agriculture, as well as the important role of enhancing the management of the ground-water dynamic information in irrigation districts and the thorough analyses of domestic and foreign research status quo of the groundwater dynamic information management in irrigation districts, the paper ascertains the research subject of the groundwater dynamic information management system (GDIMS) according the matter of the fact in irrigation districts and frames the structure and function of GDIMS, then develops GDIMS adopting synthetically advanced computer technique, database management technique, in terms of the information system theoretic and software engineering technique. GDIMS achieves the management of groundwater dynamic information in irrigation districts with computers and enhances the modernization level of the groundwater dynamic information in irrigation districts.GDIMS composes nine function modules: general situation of irrigation districts, data recording, information query, graph drawing, report output, forecast, help, exit. It is developed by oriented object programming language — VISUAL FOXPRO 6.0. The main function module of GDIMS actualized by dropped menu and transfer administrative levels through multilevel menu. The system which has rapid response, simple manipulation, friendly user interface, all-sided data disposal function is preferablely practical, advanced and transplantable.GDIMS establishes the information database of the groundwater dynamic data in irrigation districts, as well as provides information retrieve modes and general data management function. On the other hand, it forecasts the groundwater level so as to provide essential assistant decision-making information for the water resources management departments. GDIMS establishes the well data bases not only for water resources estimate, utilizing, lay out in irrigation districts but also for actualizing the automatization, standardization, network of the groundwater dynamic information management in irrigation districts, thus it has important role for the development of the irrigation districts and the increasing of national economy.更多还原
