自来水管网属于城市基础设施,其管理是一项复杂而艰巨的工作,涉及面广、数据量大、图形信息与文字信息并存、设备附件增减更新快,人工管理工作难度大、效率低。为适应现代化城市的发展,城市基础设施应具有良好的预测性、完善的决策性和快速响应性,特别是在城市基础设施覆盖面越来越大、地下管网分布密度越来越高、城市用水日益紧张的情况下,更需要一个信息容量上包容能力大、输入存储信息简便、加工处理信息能力强、显示信息速度快、信息交换便利的管理工具对管网信息进行科学高效的管理和利用。
随着GIS系统在我国各领域逐步发展应用,其强大的图形和空间数据处理能力为我们开发自来水管网管理系统提供了思路。利用目前已有的管网GIS系统数据,并在建设和使用的过程中逐步完善是建立管网信息管理系统的首选途径。本文选用组件式GIS技术,。文章阐述了该系统的功能、总体结构及系统实现。

ABSTRACT
Water-work belong to city basic facilities,the management of which is one term intricacy and collar work, because of it’s touch on surface wide, data bulk large, graphical information and letter information consist, equipment appurtenance update swiftness,labor control acting hardness large, inefficiency up more or less. For conform to modern city's develop,city basic facilities respond possess favorable predictability, sophisticated decision gender and fast response gender,especially above city basic facilities covering surface increasingly large, underground work distribution density increasingly high, town water increasingly taut on occasions, still needs for one information capacity upper contain ability large, feed canned data handiness, working over information ability strong, lay velocity swiftness, message switching convenient management tool pair information proceed science high duty supervise and utilize bare in to.
As GIS system in our country wrought up application each region,thereof powerful figure and spatial data processing ability for us exploitation water-work supervisory system supply know clearly clue. It was erect work information management system's first choice avenue for that both utilize for the moment available work GIS system bine on the stocks suppose and utilized course suffer gradually soundness. ponent-oriented GIS technology, we have developed the water-work GIS used with ponent and Advanced Language . In this paper, the function, the ensemble structure and achieveme
